How it works

The workpieces are hung onto the automatic conveyor system, where they will undergo an intense chemical cleaning and drying process in order to eliminate any dirt or debris, which can affect the powder coating finish.

The powder is then sprayed using an electrostatic gun or corona gun. The automatic gun will impart a positive electric charge into its powder, this is then directly sprayed towards the workpiece which is grounded via a mechanical or compressed air spraying and then accelerated to the approaching workpiece applying a powerful electrostatic charge.

The workpiece will then undergo a heating process to cure the item, where the powder will melt into a smooth uniform film, where it will then be cooled to ensure a hard resilient coating with a high quality finish.
