Powder coating is an eco-friendly and efficient surface finishing technology. It applies dry powder paint onto a workpiece through an electrostatic spraying process, followed by high-temperature baking that melts, levels, and cures the powder to form a durable and uniform coating.
Working Principle
Pre-treatment: A critical step to ensure coating adhesion and durability.
Electrostatic Spraying: Powder particles are charged and applied to the workpiece surface using a specialized electrostatic spray gun.
High-Temperature Curing: The coated workpiece is placed in a curing oven, where heat melts and solidifies the powder into a protective finish.
Types of Equipment
Electrostatic Spray Gun: Used to charge and apply powder particles evenly onto the workpiece.
Curing Oven: Provides controlled high temperatures for melting, leveling, and curing of the powder coating.
Applications
Home Appliances: Refrigerator, washing machine, microwave oven, oven, and air conditioner housings, offering both durability and aesthetics.
Automotive Industry: Wheel rims, frames, chassis components, under-hood parts, and exhaust systems, enhancing corrosion and weather resistance.
Machinery and Equipment: Machine tool enclosures, industrial equipment parts, and agricultural machinery, improving wear and chemical resistance.
Electronics: Computer cases and housings for electronic devices.
