Powder coating system
Tecnofirma spa
The typical system is made up of a pre-treatment tunnel, a drying oven, a mono-colour or colour change booth, polymerization oven, overhead conveyor; alternatively for large-sized components, treatment cells with step advance are used.
PROS
- Excellent surface resistance
- Automatic application
- Manual application with unskilled personnel
- High productivity
- Recovery of overspray
- Solvent-free
CONS
- Difficult to apply on very heavy structures as the polymerization requires the piece to reach the temperature of 160 180° for 15-20 mins.
- It can often not be applied to details that are already assembled, again because of the high temperatures
- Uneconomic if many colours in small batches have to be handled
- Not applicable to materials that cannot exceed certain temperatures
