Advantages
- High quality - both the production and inspection are being practiced according to ISO 9001
- Computer controlled technology
- Ability to meet varying requirements of customers
- Component finishing for complicate applications, e.g. in the area of aviation or power generation
Eloxal coating of aluminum is carried out in a computer-controlled anodic oxidation line with possibility of process data recording. The other surface finish operations are carried out in the facility, wherein the components are transported by hand-operated conveyers. In both pre-treatment and electroplating we are thus able to meet varying requirements of the customers. Both the production and inspection are carried out on the basis of ISO 9001 principles.
