High-Efficiency Powder Coating

Automatic electrostatic spray guns provide consistent coating thickness and high transfer efficiency, while optional manual touch-up stations ensure complete coverage of complex workpieces.

Reliable Process Control

Integrated control systems monitor conveyor speed, oven temperature, spray parameters, and other critical process conditions to maintain stable production quality.

Customized Engineering

The production line can be designed according to:

• Workpiece dimensions

• Production capacity

• Coating specifications

• Factory layout

• Degree of automation

Typical Powder Coating Process

Surface Preparation

Workpieces are cleaned to remove oil, dust, rust, and other contaminants, creating a clean surface for powder coating.

Pretreatment

Depending on the substrate material and coating requirements, the pretreatment process may include:

• Degreasing

• Water rinsing

• Phosphating

• Chromate or chrome-free conversion coating

• Surface conditioning

These treatments improve coating adhesion and corrosion resistance.

Drying

Residual moisture is removed in a drying oven to ensure a clean, dry surface before powder application.

Electrostatic Powder Coating

Electrostatically charged powder is applied using automatic spray guns. Optional manual touch-up stations provide additional coating for complex geometries and recessed areas.

Powder Curing

The coated workpieces enter a curing oven, where controlled heating melts and chemically cross-links the powder into a durable, continuous coating film.

Cooling

Controlled cooling stabilizes the coating and prepares the parts for inspection and handling.

Quality Inspection

Finished products are inspected for:

• Coating thickness

• Surface appearance

• Adhesion

• Color consistency

• Overall coating quality
