Excellent quality
A multi-stage pre-treatment ensures optimum cleaning of the parts, thus achieving perfect adhesion of the powder coating. State-of-the-art technology and many years of know-how guarantee uniform coating thicknesses. Maximum corrosion protection and a robust, aesthetically pleasing surface are the properties of Seven-Air powder coating.

Energy-efficient and environmentally friendly production
The powder is almost 100% recovered during operation and colour changes. The multiple use of the rinsing water keeps the fresh water requirement extremely low. The waste heat from the adhesive water dryer and the curing oven is recovered for the pre-treatment zone and for the workshop heating.

Possible materials
  • steel
  • Electrolytically galvanized steel
  • Sendzimir galvanized steel
  • Aluminium*
  • Stainless steel*
  • Grey and spheroidal graphite cast iron parts*

* The coating of aluminium, stainless steel and cast parts requires mechanical pre-treatment (e.g. sand or dust blasting) depending on the use and requirements of the parts.
