2.Recommended Coating Equipment
3.Automated Electrostatic Spray Systems
￮Ensures uniform powder adhesion to appliance surfaces.
￮Supports quick color changes, ideal for diverse product lines.
￮Equipped with efficient powder recovery systems to reduce waste and costs.
4.High-Precision Spray Guns
￮Integrated with electrostatic generators for even coating thickness.
￮Adjustable parameters (voltage, pressure, spray distance) to meet various requirements.
5.Curing Ovens
￮Uses electric or gas-heated convection curing ovens with precise temperature control (180°C-220°C).
￮Ensures proper curing of powder coatings to create robust protective layers.
6.Process Workflow
7.Pretreatment Stage
￮ Steps: Degreasing, cleaning, rinsing, and phosphating/ceramic conversion.
￮ Purpose: Cleans the surface, enhances powder adhesion, and improves corrosion resistance.
8.Powder Coating Stage
￮Utilize electrostatic spray systems, adjusting parameters based on material and shape.
￮Maintain a spray gun distance of 150-300mm from the surface for uniform coverage.
9.Curing Stage
￮ Place coated appliance parts in the curing oven.
￮ Set temperature: 180°C-220°C; curing time: 10-15 minutes (depending on the coating material).
10.Inspection Stage
￮Inspect coating thickness (60-120 microns), uniformity, and color consistency.
￮Ensure no defects such as missed areas, runs, or bubbles.
11.Features and Benefits
12.Environmental Performance
￮Powder coatings are solvent-free with zero VOC emissions, meeting environmental regulations.
￮High-efficiency powder recovery systems minimize waste and save costs.
13.Aesthetic Appeal
￮Offers diverse surface effects (matte, glossy, textured).
￮Rich color options cater to the visual needs of modern appliances.
14.Protective Properties
￮Coatings provide corrosion resistance, chemical resistance, and wear protection, extending the lifespan of appliances.
￮Antibacterial coatings enhance hygiene for components in contact with food or sensitive environments.
15.Wide Applicability
￮Suitable for various appliance materials (steel, aluminum alloys, plastic parts).
￮Flexible parameter adjustments adapt to the coating of complex shapes and designs.
16.Customization Recommendations
•For small appliances (e.g., rice cookers, microwave ovens), choose polyurethane coatings for enhanced decorative appeal.
•Use antibacterial coatings for products requiring special functionality (e.g., refrigerator interiors).
•Adopt modular production line layouts to enable rapid product switching and accommodate diverse production volumes.
