Deqing Leixin Coating Equipment Co., Ltd. proudly presents our Automatic Electrostatic Powder Coating Spraying Line, specifically engineered for automotive wheel rims and aluminum profiles. With over a decade of manufacturing expertise since 2011, we deliver a reliable, high-efficiency coating solution that ensures uniform finish, excellent adhesion, and significant cost savings. Our system integrates advanced electrostatic technology with precise automation to meet the demanding requirements of the automotive and architectural industries.
This fully automated line is designed to handle a wide range of workpiece sizes and shapes, from car wheels to extruded aluminum profiles. It features a modular structure including pretreatment, drying oven, powder booth with cyclone recovery, curing oven, and cooling tunnel – all controlled by a PLC touchscreen interface. The result: consistent coating thickness, minimal powder waste, and a production capacity of up to 300 pieces per hour for typical wheel rims.

Frequently Asked Questions (FAQ)
1. What types of powder can be used with this line?
The line is compatible with most thermosetting powders, including epoxy, polyester, polyurethane, and hybrid powders. It can also handle metallic and textured powders with appropriate adjustment of gun parameters.
2. Can the line be customized for extra-large aluminum profiles?
Yes. The conveyor width, spray booth size, and curing oven dimensions can be customized to accommodate profiles up to 6 meters or longer. Please provide your workpiece dimensions for a tailored design.
3. How long does it take to change colors?
Our modular booth design allows a complete color change (including cleaning powder hoses and cyclone) in approximately 15–20 minutes for standard colors. Automated purge systems are available to reduce changeover time further.
4. What is the typical power consumption per hour?
For a standard line processing 200 wheel rims/hour, average power consumption is around 55–65 kWh, including conveyor, oven, spray booth, and recovery system. Actual consumption depends on workpiece weight and curing temperature.
5. Do you provide installation and training?
Yes. We offer on-site supervision during installation, commissioning, and operator training (1–2 weeks, depending on complexity). Remote video support is also available for troubleshooting.
6. What safety features are included?
The line includes emergency stop buttons, overload protection, gas detection in the oven, anti-static earthing, and powder explosion-proof design compliant with international safety standards.
7. How does the powder recovery system work?
Overspray powder is collected by a cyclone separator (first stage) and a cartridge filter (second stage). Clean air is exhausted while reclaimed powder is sieved and returned to the hopper for reuse, achieving over 95% recovery efficiency.
8. What is the warranty period?
We provide a 12-month warranty from the date of shipment against manufacturing defects. Extended warranties and spare parts packages are available upon request.
