Automatic Powder Coating & Painting Line

A automatic powder coating and painting line is a specialized assembly line system used in industrial manufacturing for the surface painting and powder coating of workpieces. It comprises pre-treatment equipment, a powder coating system, painting equipment, a curing oven, a heat source system, an electrical control system, and a suspended conveyor chain. Learn More >>

Manual Powder Coating Line, Semi-automatic Painting Machine

Semi-automatic powder coating lines (Semi-automatic painting machine) primarily consists of a conveyor system, a spray booth, a spray gun assembly, a coating supply system, and a control system. The conveyor system typically utilizes a chain or belt mechanism to transport workpieces into the spraying zone sequentially at a constant speed. The spray booth is equipped with ventilation and filtration units to maintain a clean working environment. The spray gun assembly is mounted on an adjustable mechanical support, with its movement trajectory and spraying angle controlled by preset programs. The coating supply system ensures a continuous supply of coating material to the spray gun at stable pressure and flow rates. Operators are primarily responsible for loading and unloading workpieces, monitoring equipment status, and fine-tuning program parameters when necessary. Learn More >>

Electrostatic Powder Coating Line

Electrostatic powder coating lines are automated metal surface coating production lines based on the principle of electrostatic adsorption. They are mainly used for surface treatment of industrial products such as aluminum profiles, guardrails, control cabinets, air conditioner housings, fan grilles, and satellite antennas.

Powder Coating Machine & Equipments

• Electrostatic Spray Gun: Manual or automatic, maximum powder output up to 350g/min, overcoming the Faraday cage effect.
• Powder Supply Device: Powder is fluidized and transported via compressed air, supporting precise powder output control over long pipelines.
• Powder Recovery Equipment: Employs a combination of cyclone dust collectors and filter cartridges; oversprayed powder can be recycled and reused.

Electrostatic Spray Gun, Powder Coating Gun, Liquid Coating Spray Gun

The electrostatic spray gun uses the grounded workpiece as the positive electrode and the paint atomizing device as the negative electrode. The paint atomizing device is given a high negative voltage, creating an electrostatic interface between the two electrodes. This causes the atomized paint particles to become negatively charged, effectively attracting the paint to the workpiece surface, which is the opposite electrode. Learn More >>

Powder Coating Booths, Powder Spray Booths

The powder coating booths is the core equipment of the electrostatic powder coating system. Its aerodynamic design maintains a stable airflow, keeping dust content below the lower explosive limit of 10g/m³, ensuring operational safety. Constructed of stainless steel, it is equipped with a vibrating screen filter and a quick color-changing device, supporting multi-color powder interchangeability. An integrated 500LX illumination system ensures visibility during coating operations and forms an interlocking production line with the powder supply center and recovery unit, realizing a complete process flow from loading to degreasing, powder coating, and curing.

Powder Coating Oven, Powder Coating Curing Oven

The powder coating curing oven, on the other hand, is the “shaper” in electrostatic powder coating equipment, transforming the powder coating into a robust coating through heating. Learn More >>
