The whole industrial Automated Powder Coating stage is managed and carried out in-house by specialist Tecnolaser operators who closely monitor each step to ensure a final result in line with the design specifications.
Before the coating stage can begin, there is a strict cleaning procedure, which consists in:
- a phosphate degreasing stage;
- two rinses with mains water;
- a wash with demineralized water;
- a soft-rain passivation stage with a nanotechnology product that increases the corrosion resistance of the parts treated.
The coating stage takes place inside 3 GEMA booths fitted with 8 automatic electrostatic guns served by two reciprocators with motor-driven horizontal carriage.
Coated parts are then introduced into the oven cabins for the polymerization stage: constant temperature, monitored with computerized data management, ensures coating powders adhere correctly to the metal surfaces.
The "resistance/service life" of coated products is tested in a salt mist corrosion test chamber.
