Introduction of Dry-Type Furniture Powder Coating Production Line

The Dry-Type Furniture Powder Coating Production Line is an automated production system designed for surface coating treatment of furniture and furniture components. It mainly adopts electrostatic powder coating technology to provide decorative and protective surface treatment for metal furniture, furniture hardware parts, and related metal structural components.

The production line uses electrostatic spray guns to charge powder coating particles, allowing the powder to evenly adhere to the workpiece surface through electrostatic attraction. The coated workpieces then pass through a high-temperature curing oven, where the powder melts, levels, and cures to form a strong, uniform, and attractive protective coating.

Components of Dry-Type Furniture Powder Coating Production Line

The dry-type furniture powder coating production line is an automated surface treatment system integrating pretreatment, conveying, electrostatic spraying, powder recovery, curing, control, and auxiliary systems. Through the coordinated operation of each system, it enables continuous production from surface treatment, powder coating, to curing and final coating formation for furniture and metal furniture components.
