Surface treatment with powder coating substances.

Kovona System offers knowledge, technological and capacity possibilities for powder painting on automatic lines. Surface of part is firstly cleaned in degreasing section (pickling) and consequently treated by iron phosphate (passivation) before painting. Powder application technology follows. Powder is applied with use of electrostatic guns on surface of the parts. Electrostatic guns are placed in plastic cabin which allows fast change of powder colour (less than 20 minutes). Powder painting process continues by powder paint hardening in tunnel furnace with regulated temperature and speed of painted parts passage. Whole process is strictly monitored to secure constant parameters for optimal running of powder painting process.

Powder painting in Kovona System allows painting of metal parts with these basic parameters:
- Maximal length 3 000 mm.
- Structure gauge 2 000 x 600 mm.
- Maximal weight of piece 50 kg.
