Our services

Mechanical pretreatments

This aims to prepare the surface of parts for anodizing. In our company, these are performed on two robotic Cimotec and four SHL lines where we can grind, polish, or brush the parts as necessary. This pretreatment is very efficient and flexible, and can be adjusted for various product ranges.

Our company offers a wide range of surface treatments for aluminium and its alloys

• Mechanical grinding E1 - surface pre-treatment before anodizing
• Mechanical brushing E2 - surface pre-treatment before anodizing
• Mechanical polishing E3 - surface pre-treatment before anodizing
• Natural anodizing, pre-treatment E0 - degreasing and deoxidation, surface slightly shiny
