Yes, cast iron can definitely be powder coated, but this requires extremely meticulous surface preparation. Because cast iron is highly susceptible to “exhaust” phenomena ——i.e., the escape of trapped air, grease, and moisture from the metal’s microscopic pores during high-temperature curing, proper pretreatment of the cast iron substrate before coating is crucial. This step-by-step preparation typically involves removing heavy rust, old paint, and casting sand through a thorough sandblasting process, followed by pre-baking the bare metal to release any trapped gases. Porous surfaces can be effectively sealed by applying a high-quality zinc-rich primer or epoxy primer before the final powder coating is applied. This ensures maximum adhesion, prevents blistering, and creates an extremely durable, rust-resistant finish that will protect it from harsh environments for years to come.   Why Cast Iron Needs an Extremely Detailed Finish To understand how to successfully powder coat cast iron, it is first necessary to understand the unique physical structure of this metal. Unlike smooth extruded metals, cast iron is naturally porous. These microscopic pores act like tiny sponges that absorb various pollutants over time. the biggest challenge when powder coating cast iron is a phenomenon known as exhaust. The powder coating needs to be cured at high temperatures in an oven. When untreated cast iron is exposed to these extremely high curing temperatures, the air trapped within the pores, deep residual grease, and tiny amounts of moisture quickly expand and convert into gas. Without extremely careful preparation of the surface, these escaping gases can force through the curing powder, causing blemishes and bubbles in the coating. Properly addressing exhaust issues through careful preparation is the only way to ensure a smooth and flawless coating. Step-by-step preparation process for cast iron powder coating Because of the high risk of venting, you can’t simply spray powder on cast iron and bake it. Handling cast iron substrates requires a rigorous, step-by-step preparation process. Thorough sandblasting The crucial first step is a strong mechanical cleaning. Cast iron items are often covered with thick layers of rust, peeling old paint, and even casting sand from the original manufacturing process. A thorough sandblasting effectively strips away all of these impurities, leaving the item exposed as bare metal. More importantly, sandblasting opens the metal’s microscopic pores and creates a textured surface profile. This slight roughness provides the powder coating with the necessary attachment base to allow it to grip tightly, thus laying the foundation for maximum adhesion. Pre-baking of bare metal Once the cast iron has been sandblasted and stripped to its bare metal state, it must be pre-baked. This step is specifically designed to combat the phenomenon of exhaust. The uncoated bare iron is placed in a curing oven at a temperature slightly above the final powder curing temperature to artificially trigger the venting process. The extremely high heat burns off any remaining grease, evaporates hidden moisture, and forces trapped air to escape from the microscopic pores before applying any powder. Once the metal cools, these pores become clean and free of volatile contaminants. Apply zinc-rich primer or epoxy primer Even after sandblasting and pre-baking, cast iron remains highly porous. To bridge the gap between the porous substrate and the final topcoat, applying a high-quality primer is essential. Zinc-rich or epoxy primers can provide a strong seal. During the curing of the primer, it flows into the remaining microscopic pores, effectively sealing the surface and locking in any remaining gas. This sealing barrier completely eliminates the risk of blistering during the final curing stage. Surface-treated cast iron can be safely sprayed When the risk of venting is eliminated through sandblasting, pre-baking, and a high-quality primer treatment, the final powder coat can be done with confidence. Because the porous surface has been properly sealed and prepared, the final powder coating is able to achieve maximum adhesion to the cast iron substrate. No escaping trapped air, grease, and moisture means the final finish will be incredibly smooth, completely free of the pinholes and blistering issues that plague improperly treated cast iron. The result is an extremely durable, rust-resistant finish. The tightly bonded powder coating acts like an indestructible shield, ensuring your cast iron items are easily protected from harsh environmental factors and effectively protected from corrosion for years to come. People also ask about powder coatting 1. How to use powder coating machine?Connect to an air compressor, attach the grounding wire to your clean metal part, load the powder hopper, set the voltage, and spray evenly. Finally, bake the part in a curing oven. 2. Can you powder coat fiberglass?Generally, no. Fiberglass doesn’t conduct the electricity needed to attract the powder, and it cannot withstand the high oven temperatures required for curing without warping. 3. Can powder coat be painted over?Yes. Clean the surface, lightly scuff it with fine sandpaper for adhesion, wipe with a degreaser, apply a suitable primer, and then apply your liquid paint. 4. How long does powder coat last on rims?Powder coated rims typically last 15 to 20 years. However, this lifespan depends heavily on driving conditions, regular maintenance, and exposure to harsh road salts. 5. Can you paint over powder coated metal?Yes, you can paint over powder-coated metal. You must first sand the smooth surface to create a “tooth” for adhesion, clean it thoroughly, and use an etching primer before painting.

This depends on the specific coating chemistry formulation applied to your substrate. Standard powder coatings (such as polyester, polyurethane, or epoxy mixtures) can safely withstand continuous operating temperatures of 200 °F to 250 °F(93°C to 121°C) without degradation. However, for demanding industrial and automotive modification applications, high-temperature powder coatings ——coatings formulated with silicone resins and ceramic additives—— can withstand extreme high temperatures ranging from 600°F to 1,200°F+(315°C to 650°C+. It is also crucial to distinguish between the working limits of the coating and the curing temperature; while standard powders must be baked in an oven at 350 °F to 400° F (175° C to 204° C) to chemically crosslink and harden, they absolutely cannot withstand the same high temperatures in everyday use. A clear understanding of these precise thermal thresholds is crucial to prevent your coating from melting, discoloring, or flaking at high temperatures.   Standard powder coating vs. High temperature powder coating In order to choose the right surface treatment for your metalworking project, you need to understand the thermal limits of different powders in the metal surface treatment industry. Standard powder coating (up to 250°F) Standard thermosetting powders are the industry standard for everyday metal products. They are extremely resistant to UV rays, chemicals, and physical shock, but their organic polymers (such as epoxy and TGIC polyester) are not designed for extreme heat. Temperature limit: Can withstand environments up to 250 °F (121°C) continuous. It may be possible to withstand short temperature peaks of up to 300 °F (149° C), but this is not recommended. Common Applications: Aluminum alloy wheels, suspension parts, interior cabinets, patio furniture and bicycle frames. Heat resistant coating in the middle section (up to 600 °F Manufacturers use specialized silicon-modified powders when the application scenario exceeds 250°F but does not face direct combustion or open flames. Temperature limit: Continuously subjected to temperatures between 300°F and 600°F(149°C and 315°C). Common Applications: Brake calipers, engine valve compartment covers, engine blocks, and commercial lighting fixtures. Extreme High Temperature Powder Coating (Up to 1,200 °F+ This type of powder is designed for the harshest environments and is highly dependent on inorganic silicone resins and ceramic microparticles. Because they contain no organic compounds that can be burned, they offer unparalleled thermal stability. Temperature limit: Can withstand extreme heat from 600°F to 1,200°F and even higher (315°C to 650°C+). Common Applications: Exhaust manifolds, exhaust head sections, silencers, grills, wood-burning stoves, and industrial furnaces. Powder Coating Types and Maximum Temperature Limits Difference between curing temperature and working temperature In the powder coating world, one of the most common questions customers have is: “If my powder coating is baked in a 400°F oven, why can’t it withstand 400°F in real life?” The answer lies in the chemistry of the curing process. When the raw powder is coated on a bare metal substrate, it must be placed in a curing oven (usually baked at 400°F for 15-20 minutes). This high temperature melts, levels and chemically cross-links the powder to form a strong and durable protective shell. However, once this chemical reaction is complete, the structure of the coating is permanently fixed. If you reheat that standard part that has already been painted to 400°F in practice, the cross-links inside it will break, causing the coating to fail directly. In short, the curing temperature is a one-time baking condition and is by no means an indicator of the long-term heat resistance of the coating. How hot to cure powder coat So, just how high does it take to perfectly cure a powder coat? For the vast majority of standard powder coatings, the ideal cure temperature is typically between 350 °F and 400° F (175° C and 204° C) and requires constant constant temperature for 10 to 20 minutes. It is worth noting that the temperature here refers to the part metal temperature, that is, the metal substrate itself must reach this heat, not just the air temperature inside the oven. If the substrate is very heavy, it will take longer to fully warm up. In addition, certain specially formulated low temperature cured powders can complete crosslinking at around 250°F, while some extreme ceramic high temperature powders may require higher initial baking heat. Strict adherence to the curing heat recommended by the manufacturer is an absolute prerequisite for ensuring that the coating is thoroughly cross-linked and reaches its maximum heat resistance limit. What happens when powder coating overheats? Incorrect application of standard powder coatings to high-temperature components such as exhaust pipes or grill smokers can lead to rapid and noticeable coating failure. Here are the chain reactions that occur when you break your thermal limit: Tarnish and discoloration: The first signs of thermal damage are visual. A high-gloss surface can quickly become dull and dull. Light colors (especially white and bright yellow) can be scorched by the heat, permanently turning an unsightly yellow or brown. Softening and foaming: Standard polyester and epoxy powders soften when temperatures climb above 300 °F(149°C). If the temperature continues to rise to 500 °F(260°C), the coating will even simply remelt and flow. Cracking, peeling and rusting: Extreme high temperatures can completely destroy the adhesion of the coating to the metal substrate. The coating becomes brittle, cracks and peels off in flakes, leaving the underlying steel or aluminum completely exposed to air and moisture, leading to irreversible rapid oxidation and rusting. How to touch up powder coated metal Whether it’s cracking and peeling of the coating due to exceeding the thermal limit, or physical scratches from daily assembly and use, you need to master the appropriate local repair techniques. Because re-powdered painting requires the use of an electrostatic spray gun and a high-temperature oven again, which is extremely unrealistic with parts already installed, spot repairs often rely on color-matched, specialized liquid repair paints. Steps to Repair Damaged Powder Coated Metal: Air Dry and Cure: Follow the refinish instructions exactly and allow it to air dry completely naturally. For some high temperature refinish paints, thermal curing may also be required by the heat generated by running the engine. Clean the surface thoroughly: Wipe the damaged area with a mild degreaser or isopropyl alcohol. It is essential to ensure that the peeling area is free of any oil, dust or exposed rust, otherwise the new paint will not adhere. Lightly Sand Edges: Use fine sandpaper (such as around 400 grit) to lightly sand the edges of the damaged area. This step removes loose residual coating and smoothes the transition between the old coating and the bare metal, increasing the mechanical adhesion of the refinish paint. Apply touch-up paint: Apply a matching liquid touch-up paint evenly using a fine-bristled brush or spray, depending on the size of the scratch or shed area. A very critical point is: If your metal parts are working at high temperatures (such as engine parts or exhaust pipes), be sure to repair them with a special high-temperature resistant automotive paint or ceramic paint; if you use regular repair paint, it will quickly blister and burn out again at high temperatures. Choosing the right powder for different temperature applications It can be seen that the standard powder coating is exceptionally durable, but can only withstand operating temperatures of up to 250 °F (121°C). If your project involves an engine, exhaust system or heating appliances, you must decisively upgrade to use high-temperature powder coating, which can safely protect your metal parts in harsh environments up to 1,200 °F+ (650 °C+). By matching the right chemical formula to the heat exposure environment your part is expected to experience, you’re guaranteed to get a flawless, corrosion-resistant, and time-tested coating. Frequently Asked Questions About Powder Coating 1. can powder coating withstand heatYes. Standard powder coat safely handles up to 250°F (121°C). For extreme parts like exhausts, specialized high-temp powders are used, which can withstand heat up to 1,200°F+ (650°C+). 2. does powder coated steel get hot in the sunYes. Powder-coated steel absorbs heat in direct sunlight, especially dark colors. However, this solar heat is far below its 250°F limit and will absolutely not melt or damage the finish. 3. how hot to cure powder coatMost standard powder coats cure at 350°F to 400°F (175°C to 204°C) for 10-20 minutes. Note that this target temperature must be reached by the metal substrate itself, not just the oven air. 4. how to clean powder coated metalClean the surface using warm water, mild dish soap, and a soft microfiber cloth. Avoid harsh chemicals, acetone, or abrasive scrubbers, which can permanently scratch or dull the finish.   What Temperature Can Powder Coat Withstand-Plus Powder Form  

To build a powder coating booth in a factory, we first need to build a stable support body and a suspended conveying network, and then accurately connect it to the large cyclone recovery tower to achieve excellent gas-solid separation. The entire system must rely on precision air ducts that conform to fluid dynamics design for series connection, and pulse back-blow filter element dust collectors must be deployed at the final exhaust end to truly achieve green and standard-compliant environmentally friendly emissions. A qualified powder booth contains an extractor fan accurately calculated for optimal cross-section wind speeds (typically 100-120 ft/min), grounding equipment, and an efficient recovery unit. It will control overspray, protect operators and recover unattached powder. Note, install the explosion-proof fan, and when your spray booth is integrated with the dedicated compressed air cold dryer, electrostatic spray gun and curing furnace, remember to ground the entire structure. what is a powder coating system​? The powder coating system is an integrated mechanical and electrostatic circulation loop designed to apply dry powder to a grounded substrate and efficiently recover any wasted material. It goes far beyond simple airbrushes and exhaust fans. Industrial-grade equipment utilizes automated assembly lines, precisely positioned reciprocating machines, and multi-stage air filtration to maintain continuous production cycles.     what equipment is needed for powder coating? You need specific industrial hardware to build a viable production line. Reliance on improvised pieces of parts leads to unsafe levels of flammable dust concentration and ruins the coating surface quality. Spray booth housing: Polypropylene or anti-static stainless steel panel to prevent powder from adhering to the wall. Suspended conveying system: Grounded track that transports workpieces through the spraying area at a controlled speed. Electrostatic spray gun and reciprocating machine: A robotic arm that automatically sprays powder with consistent coating thickness. Extraction and filtration unit: Precisely sized exhaust fan that extracts air evenly across all openings in the spray booth. Powder recovery system: Cyclone separator with rear filter element for capturing and reusing sprayed powder. Step 1: Build a closed and controlled spray booth structure       The geometry of the spray chamber directly determines the surface coating quality. A poorly shaped enclosure creates turbulence in the airflow. Specific construction and grounding steps of the closed control link The spray booth housing is assembled to create an electrostatic isolation zone that is free of dead spots and fully grounded. 1.1 Building the external load-bearing frame and inner wall panels Never expose the structural skeleton inside the spray booth, as this will create a powder accumulation platform that is extremely difficult to clean. A strong external load-bearing frame must first be welded using carbon steel square tubing (recommended gauge is four by four inches).After the skeleton is completed, a polypropylene panel or an anti-static stainless steel plate is fixed to the inner side of the skeleton. The panel-to-panel seams must be secured with flat-head countersunk screws and sealed with anti-static silicone, ensuring the entire spray booth interior is mirror-flat without any protruding flanges or bolt heads. 1.2 Precisely cut openings and control electrostatic spacing Cut a through slot in the top of the spray house, depending on your hanging conveyor track. Calculating the distance from the spray gun to the nearest spray chamber wall, a radius clearance of at least thirty-six inches (about one meter) must be strictly maintained. If the gap is too small, the high-voltage static electricity from the spray gun will occur “Faraday cage effect”, adsorbing the powder directly onto the wall instead of the workpiece you are spraying. 1.3 Build an independent grounding network Never use conventional grounding wires from factory buildings. A special pure copper ground rod at least eight feet deep must be driven into the concrete floor next to the spray house. This ground bar is hard-wired with bare copper braided wire to the steel track of the suspended conveyor, the workpiece hangers, and the metal parts of the spray booth (if stainless steel walls are used). After construction is completed, the resistance value between the workpiece and the ground wire must be less than one megohm using a megohmeter test. Step 2: Fluid Mechanics Configuration of Airflow Management Don’t just buy an exhaust fan and install it. You have to design the static pressure box and the exhaust duct according to fluid mechanics standards. 2.1 Calculate the absolute exhaust volume and select the fan Measure all the opening areas of the spray booth that are connected to the outside world. Suppose you have two doors for the operator to spray (three by seven feet each), plus the conveyor opening at the top, for a total open area of fifty square feet. To achieve the industry standard of one hundred and twenty feet per minute of cross-sectional wind speed, the formula is: fifty times one hundred and twenty, which equals six thousand cubic feet per minute.When purchasing a fan, you must choose a backward-tilting centrifugal fan and absolutely do not use an axial flow fan. Because the powder filtration system will produce extremely high static pressure resistance, only the centrifugal fan can maintain a stable air extraction volume even when the filter element is gradually blocked. 2.2 Post-assembly static pressure box and slotted deflector A static pressure extraction box of equal height and width to the spray booth is constructed directly behind the spray booth. The key operation is at the junction of the spray booth and the static pressure box: do not leave a huge hole for the exhaust. You have to install a row of slotted deflectors with vertical slits. The narrow top slit and wide bottom slit force the powerful air flow to sweep evenly from top to bottom across the entire work area, completely eliminating the dead-angle powder gathering problem in the four corners of the spray booth. Step 3: Automatically switch the pipeline connection and integration of the powder recovery system This step is at the heart of achieving a rapid fifteen-minute color change. You need to seamlessly connect the spray booth vents on the front end to the dual-stage recovery equipment on the back end. 3.1 Use a round tube to connect the cyclone separator Exhaust duct leads from the top of the static pressure box of the spray booth, connecting it directly to the side air inlet of the large cyclone separator. This connecting pipe must use a round pipe with an extremely smooth interior. Square pipes are strictly prohibited. The ninety-degree inner angle of square pipes will quickly accumulate powder, which can easily fall off during color change and cause serious cross-contamination. The elbows of all pipes must be smooth transition elbows of large radius. 3.2 Establishment of a physical circuit for powder reflux at the bottom At the bottom discharge port of the cyclone separator, a rotary discharge valve is connected through a flange. The valve allows the system to remain airtight while allowing the falling usable powder to be discharged evenly. A circular ultrasonic vibrating screen is installed directly below the discharge valve to filter out impurities or lumps that may be mixed into the powder. Finally, the sieved pure powder is pumped directly back to the main powder supply barrel through the antistatic powder tube through a venturi powder pump or peristaltic pump to form a closed loop. 3.3 Connecting the secondary filter cartridge to the configuration pulse backblow The exhaust port at the top of the cyclone separator discharges a high-speed air flow containing extremely fine waste dust. This exhaust port is piped into the secondary filter cartridge collection box. Install the laminated filter elements side by side in this collection box. At this stage, a gas tank and a pulse backblow solenoid valve must be installed directly above each filter element. Set the solenoid valve to spray high-pressure air into the inside of the filter element every thirty seconds to shock the waste dust attached to the outside of the filter element into the garbage drawer at the bottom. This guarantees that your main exhaust fan will never lose suction due to a clogged filter. How do you measure powder coating shop efficiency? Successful spray booth construction relies on the CFR efficiency pyramid: containment control, airflow management, and powder recovery. You have to master each layer in turn. Failure of the bottom layer containment control is bound to lead to failure of the top layer powder recovery. Efficiency is not measured by how many workpieces leave the oven each day, but by powder utilization and reduced downtime. Track your system’s transmission efficiency. To calculate this metric, record the exact weight of powder ejected from the lance and compare it to the weight of permanently cured powder on the workpiece. Optimized spray booths equipped with high-end cyclone recovery systems should maintain 95% or higher system transmission efficiency. FAQ About Powder Coating Spray Booth Q: What is a powder coating system?A: An integrated industrial assembly line that uses static electricity to evenly apply dry powder to grounded workpieces, cures at high temperatures to form a durable coating, and relies on an automatic recovery unit to collect overspray powder for recycling. Q: What equipment is needed for powder coating?A: Core equipment includes: surface pre-treatment cleaning line, anti-static powder booth shell, electrostatic spray gun and automatic reciprocating machine, powder curing oven, and powder recovery system including cyclone separator and secondary filter element. Q: How much does a powder coating system cost?A: Costs vary by size. Entry-level commercial manual systems typically cost between $10,000 and $50,000, while industrial-grade production lines equipped with automatic switching recovery systems, reciprocating machines, and fully automated conveyor lines typically cost more than $100,000 to $500,000. Q: How do you measure powder coating shop efficiency?A: Mainly through two indicators: one is the system transmission efficiency (the weight ratio of the powder actually solidified on the workpiece to the total ejected powder should reach more than 95%); the other is the color change downtime (an excellent cyclone system can compress it to within 15 minutes). Q: Does the powder booth need fresh air?A: Need. If you’re venting 5,000 cubic feet per minute of air from the shop outward, you’ll have to introduce an equal amount of fresh, temperature-controlled make-up air. Negative pressure in the workshop can cause dust contamination and trigger air flow disturbances in the spray booth Q: How often should the filter element in the powder coating booth be replaced?A: In systems without cyclones, the primary filter element needs to be replaced every 6 to 12 months, depending on how often it is used. In cyclone systems, the final rear filter cartridges last 2 to 3 years because they only need to handle very small amounts of fine dust.

Every March, we celebrate a special holiday—International Women's Day. This day is not merely about flowers and praise; it carries the weight of a century-long struggle for equality, dignity, and rights. The origins of Women's Day trace back to the labor movement of the early 20th century. On March 8, 1857, female garment and textile workers in New York City took to the streets to protest inhumane working conditions, 12-hour workdays, and low wages. On March 8, 1908, 15,000 women marched through Manhattan, chanting the powerful slogan: “Bread and Roses.” Bread symbolized economic security, while roses represented a better life. In 1910, Clara Zetkin, a leader of the international socialist women's movement, proposed establishing an International Women's Day at a conference in Copenhagen, gaining unanimous support. In 1917, the heroic struggle of Russian female workers during the February Revolution ultimately cemented March 8th as this glorious holiday. Looking back at history is to better move forward into the future. From fighting for suffrage to pursuing workplace equality, from opposing discrimination to safeguarding legitimate rights and interests, generation after generation of women have carved indelible marks in the river of history with courage and wisdom. Today, standing on the shoulders of giants, we must grasp the power in our hands even more firmly—the right to equal development, the right to free choice, and the right to pursue our dreams. Dear sisters, whether you are a corporate leader, a scientific pioneer, an entrepreneur, or an ordinary soul quietly cultivating your path—know this: your strength cannot be overlooked, your radiance irreplaceable.

Case Background The client company is a globally renowned leader in the forklift industry. In 2021, it invested $132 million to build a smart (connected) factory, enabling interconnected operations such as remote equipment maintenance, online production process management, and real-time supply chain updates. In July 2022, the client entered into an in-depth customized partnership with Junhe. Following multiple rounds of on-site surveys and solution discussions, Junhe designed specialized automated powder coating equipment for the client's forklift production line. This equipment officially launched and commenced operations in March 2023. Through automated equipment and intelligent digital services, the client company achieved a significant developmental leap, sustaining its competitive edge and leading position while harmoniously integrating quality enhancement, efficiency gains, environmental sustainability, and smart operations. Project Implementation and Highlights Addressing the client company's requirements and pain points, along with the unique characteristics of forklift structures, Junhe Design developed and manufactured automated powder coating equipment through multiple rounds of technical discussions and validation. This solution delivers the following benefits: (1) Enhanced automatic spray coverage, reducing manual touch-up requirements. (2) Optimized program control with dual automatic spray systems, enabling flexible production for both chassis and mast components. (3) Enhanced coating process quality through the integration of a buffer zone between manual and automated spray sections, significantly improving overall coating consistency. [Highlight: Utilization of Two Ultra-Long Multi-Functional Intelligent Spraying Systems] The automated powder coating line employs Junhe's newly customized and designed ultra-long multi-functional spray booth series PX01. This booth features workpiece buffer zones in both the automatic spraying section and the preceding/subsequent manual spraying sections. This allows workpieces in the manual sections to pause for spraying without impacting overall production rhythm and efficiency. Compared to manual spraying, coating quality improves by 35%. The ergonomic design reduces operator fatigue and enhances work efficiency. This spray booth features two buffer stations and spans approximately 20 meters in length, demanding high standards for uniform airflow distribution throughout. Through computational fluid dynamics (CFD) analysis combined with practical field experience data, an advanced airflow distribution design was implemented. This enables more rational exhaust ventilation configuration, enhancing both spraying efficiency and the working environment for operators. Highlights: The intelligent spraying system delivers customized automated coating tailored to the characteristics of the two major structural components of forklifts—the mast and chassis. 1) Mast Spray Booth Highlights Each mast level is equipped with two telescopic U-axis motion mechanisms, totaling six telescopic spray units. Each unit employs a high-precision servo control system for exceptional operational stability. The transmission mechanism utilizes ultra-quiet rack-and-pinion gears with low friction coefficients, minimizing maintenance costs. For the workpiece sides, R01 series lightweight 2D sprayers are employed. Due to the low clearance at the bottom of the third mast layer relative to the operating surface, manual touch-up spraying is challenging. Therefore, KP-02 series bottom-tracking 2D sprayers are installed. Both the X-axis and Z-axis utilize high-precision servo control systems to enhance bottom coating quality. This booth also accommodates spraying of guardrails and other small components. 2) Frame Spray Booth Highlights: Features a multi-stage synchronized drive system with MU-Z axes + U axes, with each spray machine equipped with 3 MU-Z axes and 4 U axes. This system fully accommodates diverse frame structures of varying dimensions, eliminating the need for program updates when expanding applications for new customer products. This booth offers cost-effective construction, rapid commissioning, and exceptional value. It shortens engineering debugging time while accelerating production deployment. Workpiece side surfaces are coated using R01 series lightweight 2D spray machines. Highlight: Laser Dynamic Profile Recognition System Using a laser scanner to capture the contour information of workpieces requiring spraying, this data undergoes computer processing before being transmitted to the PLC. The PLC then drives the servo controller, which in turn operates the corresponding spray gun to perform contour-following spraying, thereby achieving maximum automation in the spraying process.

To enhance all employees' awareness of fire prevention, disseminate essential fire safety knowledge, and equip them with critical evacuation and self-rescue skills, JONHE Machinery & Electronics meticulously organized a comprehensive and in-depth fire drill on August 22, 2025. The drill aimed to effectively prevent various types of fire incidents, mitigate potential impacts on personnel, property, and the environment, and provide an intuitive and standardized demonstration of fire emergency procedures. Through this exercise, employees gained practical understanding of basic fire prevention and escape techniques. Furthermore, the activity strengthened the company’s Four Core Capabilities in fire safety: the ability to inspect and eliminate fire hazards, the ability to organize and execute initial fire suppression, the ability to evacuate personnel efficiently, and the ability to conduct fire safety education and training. This drill not served as a practical test of the company’s safety management system but also demonstrated its active commitment to social responsibility and the protection of employees' lives and property. The drill simulated an emergency scenario in which a fire broke out suddenly in the production workshop and spread rapidly. The moment the alarm sounded, all employees immediately stopped their work and, following pre-established evacuation routes, quickly and orderly evacuated from all workshops and offices. Inside the evacuation passages, safety guides calmly directed the crowd, ensuring that everyone remained calm and avoided congestion. The evacuation proceeded efficiently from the workshops all the way to the designated safe assembly point. At the assembly area, the company’s fire safety management team had long been ready and waiting. Equipped with professional devices, they delivered an informative and practical session on fire safety knowledge. Covering everything from the causes and types of fires to the correct usage and applicable scenarios of different types of fire extinguishers, as well as self-rescue and mutual-aid techniques in fire emergencies, they broke down complex fire safety concepts into clear and accessible language. Employees listened with great attention, frequently raising their phones to capture photos of key information for future reference. To ensure everyone truly mastered firefighting skills, a simulated fire scene was set up during the drill. The fire safety manager first demonstrated the correct way to use a fire extinguisher: "Lift, Pull, Aim, Squeeze." Then, under the guidance of the safety team, employees took turns picking up extinguishers, aiming at the raging flames, and pressing the handle. White foam burst out instantly, and the fire was quickly suppressed. Although some employees showed a bit of nervousness during the operation, everyone successfully completed the task with encouragement and corrective feedback from the instructors. Through this hands-on experience, the staff gained a deep understanding that using an extinguisher is not as easy as it seems—and that only through regular practice can one stay calm and respond effectively in a real fire.  Following the conclusion of the drill, the fire safety management department conducted a thorough summary and analysis of the activity. It was noted during the review that the entire process—from the sounding of the alarm to the assembly at the safe point and the completion of headcount—took a total of 10 minutes. However, the golden window for fire evacuation is typically 5–6 minutes. The meeting highlighted that the overall evacuation speed must be improved, and pointed out that some employees did not follow the correct procedures when using fire extinguishers. In closing, the fire safety lead emphasized:“Safety is no small matter. Today’s exercise is only the beginning. We must maintain constant vigilance toward protecting lives and property, and keep safety top of mind in our daily work.”

Amidst the hectic pace of work, time seems to have accelerated, with everyone sprinting at full speed in their respective roles. To allow employees to unwind completely after periods of intense work and further strengthen company cohesion, our company meticulously planned a summer parent-child trip—a two-day, one-night journey to Zhuhai's Chimelong Ocean Kingdom, Haiquan Bay Resort, and Feisha Beach. On the day of departure, the weather was perfect with gentle sunshine and a pleasant breeze. The tour bus was parked early at the designated spot, and employees, accompanied by their families, boarded one after another with excited and expectant smiles. The children, especially, chattered like cheerful little birds, eagerly discussing the marine life and beautiful beaches they were about to see. Laughter and lively conversation filled the bus throughout the journey, as everyone looked forward to the trip with great anticipation and excitement. On the first morning, we stepped into the world's largest ocean-themed park—Zhuhai Chimelong Ocean Kingdom. Under the towering 63-meter-tall whale shark sculpture, our adventure into the deep blue began. Inside the Whale Shark Exhibit, a breathtaking world of 31,000 cubic meters of water left everyone in awe. With 15,000 rare fish swimming around us, giant whale sharks glided gracefully behind the 8.3-meter-high acrylic viewing panel, and manta rays with wingspans of up to 4 meters seemed almost within reach. Kids pressed their faces against the glass, gasping in wonder, while adults lifted their phones to capture the unforgettable moment. Then came the Super Rapids—a thrilling water ride that blends speed and fantasy. Located in the "Walrus Mountain" zone of the park, this attraction is known for its excitement and immersive storytelling. It’s not just the most scream-inducing ride in Chimelong; it’s a perfect mix of natural scenery and mechanical brilliance. The moment the raft broke through the waves, all the stress and tiredness from work were left behind—replaced only by the thrill of the ride and the laughter that followed. The next day, we arrived at Feisha Beach. The sand was soft and bright, the water crystal clear. Under a sky of blue and white clouds, we waded into sparkling waves under the sun—the waves gently soaking our clothes, the sunset warming our faces with its glow. It was summer romance at its finest.   We walked along the shore, listening to the ocean, stepping into the waves, feeling the sea breeze. The wind whispered gently in our ears; the tide generously gifted us with seashells along the sand. As the sunset dyed the sky the color of orange soda, we stood by the sea—wordless, and completely content. The summer beach is a natural canvas where fine sand becomes dreamy castles, each one holding a childlike wonder. It’s also a natural playground where colorful swim rings bob on the waves, and a treasure ground where little shovels and buckets lead the way to adventure. Together we sail, riding the wind and breaking through the waves, journeying thousands of miles.Looking forward to next time—when we continue to join hands and discover even more beautiful scenery.  

With the continuous advancement of technology and increasing demands for quality of life, kitchen appliances are playing an increasingly important role in modern households. Electrostatic powder coating, as an efficient and environmentally friendly advanced surface treatment technology, has gradually become a critical component in the production of kitchen appliances. The client is a large kitchen appliance enterprise integrating design, development, and production. It specializes in the R&D and manufacturing of various types of integrated stoves and range hoods, possessing industry-leading technological expertise. As one of the few manufacturers domestically and internationally focused exclusively on the production of kitchen appliances, the company has developed over 400 different types of kitchen appliance products since its establishment. Its products are exported to Southeast Asia, the Middle East, Europe, the United States, and many other countries and regions. With more than 60 patents for range hood technologies, it has filled several gaps in the domestic market and serves as a key supplier for top-tier brands in China. In January 2023, after multiple on-site inspections and project discussions, our company tailored two sets of fully automated movable large-cyclone rapid color change systems based on the client’s coating requirements and facility characteristics. These systems were officially launched and put into operation in April 2023. By leveraging automated equipment and intelligent digital services, we assisted the client in achieving an upgrade and leap in smart manufacturing. The new production model has enabled the development of more high-quality, low-cost products, realizing an organic and coordinated improvement in quality, efficiency, environmental sustainability, and intelligence. Based on the customer's requirements and the specific structure of range hoods, through multiple rounds of technical discussions and on-site studies, the automated spraying equipment we provided for the final project implementation needed to meet the following customer demands:(1) Due to the low height of the workshop, the complete set of spraying equipment had to comply with the site’s height restrictions while ensuring optimal performance.(2) During color change operations, production efficiency must not be affected. The production line must not need to stop, and the system must allow one powder room to undergo color change while another continues normal spraying operations.(3) The powder room is equipped with a fixed gun mounting system, enabling spray guns to adjust their angles and positions at any time according to the structure and characteristics of different workpieces. After numerous on-site evaluations, it was determined that the client's facility features generally low ceiling heights. Conventional single-pipe cyclone separator setups would have significantly compromised powder recovery rates due to these height constraints. Remaining committed to our customer-first philosophy, we specifically developed and engineered a dual-pipe cyclone separator system for this scenario. This solution not only resolved the challenge of equipment installation but also ensured outstanding recovery performance. The powder supply center utilizes PLC programming and is operated via a touchscreen interface, which displays real-time operational statuses, fault alarms, parameter settings, and manual/automatic operation modes. It allows for the preset and easy modification of multiple predefined parameters tailored to different workpieces. Color changeovers can be performed quickly and easily by a single operator, reducing labor requirements and improving efficiency.A single lifting unit can simultaneously carry six automatic spray guns for reciprocating vertical movement. To accommodate the client's limited space, the base of the lifter was designed with a compact footprint, ensuring it fits even in narrow areas. Furthermore, the height and travel distance of the lifter were custom-designed to guarantee complete coating coverage while helping the client achieve optimal spraying results at the lowest possible cost. A single fixed gun mount can hold four spray guns, enabling pre-spraying of hard-to-reach areas on both sides of the workpiece to prevent missed or incorrect spraying.Depending on the workpiece structure, the fixed guns can adjust their position and angle accordingly.Pre-spraying reduces the need for manual touch-ups and improves production efficiency.To meet the client's need for rapid color changes in two-tone coating and their high conveyor speed, we provided an automated powder room mobile platform. The client can pause and move one powder room aside for color change while continuing to spray another color, ensuring uninterrupted production. This allows preparation for the next color without stopping the line, maintaining quality while improving efficiency. In the production of kitchen appliances, the application of electrostatic powder coating equipment not only enhances product quality and appearance but also delivers significant economic benefits. Compared to traditional liquid coating technology, electrostatic powder coating is more efficient, saving both coating materials and energy. Furthermore, the process requires no solvents, reducing waste generation and disposal costs. As a result, the use of electrostatic powder coating equipment in kitchen appliance manufacturing not only meets environmental requirements but also improves corporate competitiveness and profitability.

The conference centered on discussions regarding topics aimed at fostering high-quality development within the manufacturing sector, including the pathways for realizing automated transformation and upgrading, as well as the deep integration of manufacturing with the digital economy. As a leading enterprise in the electrostatic coating equipment sector—boasting over two decades of experience in the finishing industry—Joihey Company was honored to have its General Manager, Mr. Xie Zhichao, serve as a distinguished guest speaker at the conference. Delivering a presentation titled "Eco-friendly Electrostatic Powder Coating and Automation for Specialized Vehicles," Mr. Xie offered an in-depth analysis of the development and process upgrades regarding intelligent, automated coating manufacturing within the specialized vehicle industry. He elucidated the current landscape and future trends, while also providing an overview of the principles and characteristics of electrostatic powder spraying. Indeed, intelligent automated manufacturing has emerged as a pivotal instrument for accelerating the construction of a modern industrial system, as well as a primary strategic direction for driving the transformation and upgrading of the manufacturing sector. Currently, the construction machinery industry faces a landscape characterized by increasingly stringent national environmental and safety regulations, inherent defects in traditional coating processes, the imperative for corporate industrial upgrading, and high operating costs. As a core driving force of the Industry 4.0 era, intelligent manufacturing is gradually becoming the mainstream. Compared to traditional manual painting techniques, automated powder coating processes offer distinct advantages, including low initial investment, minimal pollution, low material consumption, reduced operating costs, and high efficiency. Principle: Powder coating involves using specialized spraying equipment to apply a powder-based coating onto the surface of a workpiece. Under the influence of electrostatic forces, the powder adheres uniformly to the workpiece surface, forming a powdery layer. This powdery layer is then subjected to high-temperature baking, during which it melts, levels out, and cures to form a final coating with a variety of distinct finishes. Features: By integrating smart and digital technologies into the spraying process, this system effectively leverages Internet of Things (IoT) technologies to enhance the management of coating equipment. This approach improves the controllability of the production process, minimizes manual intervention on the production line, enables the real-time collection of production data, and facilitates the rational scheduling of production plans and progress. Ultimately, it fulfills comprehensive requirements for quality traceability, equipment awareness, remote monitoring and control, and data analytics—thereby establishing a coating production chain that is highly efficient, energy-saving, eco-friendly, and ergonomically designed for a comfortable working environment. Currently, digitalization and intelligentization represent key trends in the development of China's real economy, as well as the indispensable path toward building a manufacturing powerhouse and a nation of high-quality production. Moving forward, Junhe will keep pace with the currents of the times, fully leveraging its technological strengths to focus closely on the high-end, intelligent, and green development of the manufacturing sector.
