Complete Home Appliance Powder Coating Process
The reference process follows: hanging workpieces, spray pre-treatment, drying oven, powder coating room, powder coating, curing oven, cooling, and removing workpieces.
Stage 1: Hanging Workpieces
Air conditioner casings and appliance parts are hung on fixtures. Correct hanging supports grounding, coating coverage, and conveyor stability.
Stage 2: Spray Pre-Treatment
A high-pressure water pump forms treatment liquid into mist and sprays it evenly onto the workpiece surface, cleaning the part and improving coating adhesion.
Stage 3: Drying Oven
After spray pre-treatment, workpieces enter the drying oven. Complete drying helps avoid bubbles, pinholes, and poor coating adhesion.
Stage 4: Powder Coating Room
The workpiece enters the PP large cyclone automatic powder room. Charged powder particles are evenly adsorbed onto the grounded surface due to electrostatic force.
Stage 5: Curing Oven
After powder coating, the workpiece enters the curing oven. Powder melts and solidifies into a uniform, smooth, anti-corrosion coating film.
Stage 6: Cooling and Removing Workpiece
After curing is completed, the product is cooled, removed, inspected, and prepared for assembly or packaging.
