Our Three Step Process
The powder coating process begins with a complete cleaning to remove any surface contaminants such as corrosion, dust or oils. The cleaning process can consist of sand blasting, chemical cleaning, or a combination of the two.
After cleaning, the work piece is moved to the enclosed and ventilated spray booth. A slight negative electrical charge is applied to the work piece and powder is applied through a specialized nozzle that imparts a positive charge to the paint particles. The positively charged powder is attracted to the negatively charged work piece and a smooth, even coat of powder is produced.
After powder, the workpiece is moved to the curing oven. Normally the powders cure at 200°C (390°F) in 10 minutes. The curing schedule could vary according to the manufacturer’s specifications.
We utilize DuBois Chemicals to further reduce the environmental impact of powder coating and the chemical cleaning process.
