Principles of fluidized bed
The part to be coated is preheated in an oven to a temperature slightly above the melting point of the polymer powder. It is then necessary to immerse the heated part in a previously fluidized powder bath. The fine powder in suspension immediately melts on contact with the hot part, on which it adheres, to create a uniform coating. The thickness of the coating depends on the immersion time and the preheating temperature.
- Thickness to be deposited: from 200 to 500 microns
- Application temperature: from 250 to 400°C
The benefits of the fluidized bed
- Overall coating in one operation
- Internal and external coating on complex shaped parts in a single operation
- Thick coating with outstanding mechanical or anti-corrosion properties
