Introduction of Through-Type Electrophoresis Coating Equipment

Through-type electrophoresis coating equipment is an automated production system designed for electrophoretic coating treatment of metal workpiece surfaces. It is mainly used for protective coating processing of automotive parts, hardware products, mechanical equipment, aluminum alloy components, and various metal structural parts.

The equipment adopts a continuous through-type conveying structure, allowing workpieces to pass sequentially through processes such as pretreatment, electrophoresis coating, electrophoretic rinsing, and drying curing. Through electrophoretic coating technology, charged coating particles are uniformly deposited onto the surface of metal workpieces under the action of an electric field, forming a uniform, dense, and highly adhesive protective coating.

Compared with traditional spraying processes, through-type electrophoresis coating equipment features excellent coating uniformity, strong coverage capability for complex structures, superior corrosion resistance, high automation level, and high production efficiency. It is suitable for large-scale continuous metal surface treatment production.

Configuration of Through-Type Electrophoresis Coating Equipment

Through-type electrophoresis coating equipment mainly consists of an automatic conveying system, pretreatment system, electrophoresis tank system, electrophoresis circulation system, cleaning system, curing system, and intelligent control system.

The equipment adopts a continuous through-type production method and can be customized according to workpiece size, production capacity requirements, and coating performance requirements, achieving automated and continuous electrophoretic coating production.
