Hardware Powder Coating

The powder coating line for hardware components is an automated surface treatment system based on the principle of electrostatic adsorption. It’s primarily used for coating metal products, where high-voltage static electricity ensures that powder adheres evenly to the workpiece surface, forming a protective layer after being cured at high temperatures.
  • Product Description
  • | Core Process 
    Pre-processing: This includes processes such as degreasing, derusting, and phosphating to ensure the workpiece surface is clean and to enhance adhesion. 
    Electrostatic Spraying: A high-voltage electrostatic generator charges the powder, which is then attracted to the workpiece surface by the electrostatic field, enabling multi-angle spraying. 
    High-temperature curing: Typically baked at 180–220°C for 10–15 minutes to form a dense coating.

     

    | Equipment Composition 
    Powder Supply System: Utilizing compressed air for powder delivery, it supports precise control of powder output via piping. 
    Spray Unit: Equipped with an automatic spray gun and powder coating booth, the system uses high-voltage electrostatic force to adhere powder onto the surface of the workpiece. 
    Recycling device: The system employs a cyclone dust collector combined with a filter cartridge, achieving a powder recovery rate of over 85%.


    | Scope of Application | 
    Suitable for surface treatment of metal products such as security doors, filing cabinets, automotive components, and electronic device housings. The maximum processing dimensions can reach 6000 × 750 × 1500 mm, with individual piece weights up to ≤300 kg.


    | Technological Advantages 
    Compared to traditional spray painting techniques, this technology features the following characteristics: 
    Environmental Protection: No diluents required—meets VOCs emission standards. 
    Efficient: Automated assembly line operations boost efficiency by more than three times. 
    Durable: Coating thickness: 50–80 μm, highly corrosion-resistant, and effectively fills surface imperfections.
