Automatic Powder Coating System for Powder Coating Kits, GC21A
- Output Voltage 100kV
- Input Pressure 5.5-6bar
- Maximum Powder Output 420g/min
Developed for large-scale production on modern automated coating lines, the automatic powder coating system for powder coating kits, GC21A delivers advanced digital control over coating process parameters. Its core control unit supports up to 20 programmable coating programs, allowing operators to preset the optimal coating strategy for different workpieces.
Our customized powder coating service covers the full process from requirement analysis and solution design to equipment maintenance. Based on the characteristics and production needs of different industries such as home appliances, building materials, aluminum processing, heavy industry, construction machinery, MDF furniture, and new energy vehicles, Haztek provides complete and efficient coating line solutions tailored to your project. From plant layout and equipment selection to process design and automation integration, the system supports a one-stop turnkey coating solution.
- Vertical Coating Lines for Architectural Aluminum Profiles
For aluminum profiles measuring several meters in length, the GC21A can work together with reciprocators to deliver a highly consistent spray pattern. Its 250 stored programs can retain specific air pressure parameters for hundreds of profile types, allowing quick line changeover with one-touch program switching.
- Horizontal Coating Lines for Medium-Sized Hardware Parts
Suitable for products such as automotive parts, fitness equipment, hardware furniture, door and window accessories, and shelving components. The system helps maintain stable powder transfer efficiency and consistent coating thickness even on high-speed production lines.
