Dip-spin
Widely used in the automotive and electromechanical industries, dip spin is a technique for depositing zinc flakes on small parts to be coated in bulk.
The principles of dip spin
After a surface preparation adapted to the parts to be coated, these are immersed in a bath containing a liquid paint. They are then centrifugated at high speed in order to leave on their surface only a thin and homogeneous wet film of paint. The applied layer is thin and uniform. This film is then dried and then polymerized at low temperature.
A second coating is usually applied afterwards as required. The parts are therefore cooled so that a new layer is produced. As a result, this process allows the production of multifunctional coatings by stacking layers of different materials.
- Polymerization at low temperature: below 250°C
- Over 100 coatings available
- Rates of up to 2 tons of coated parts per hour
The benefits of dip spin
- Very thin coatings from 8 to 25 microns
- Economic solution
- Ability to coat complex shaped parts
- Possibility of applying several treatments responding to different issues
