Surface treatment

We offer two kinds of surface treatment options for metal products and components. Surface treatment is done to achieve different features for protection, visual effects and electrical conductivity.

 

Electrochemical plating

Electrochemical plating gives products good protection against corrosion, among other things. The plating technologies of Ouneva Group have been used primarily to create surfaces, that conduct electricity very well. Tin-plating for copper and aluminium enables connector products to be connected without the oxidization of the connecting surfaces. Gold, nickel and silver give products with low voltage and power values excellent electrical conductivity. Telecommunications connectors are a good example of these kinds of products. Electrochemical plating can be done with racks, drums or with reel-to-reel plating. The quality control of plating happens in our own laboratory with X-ray inspection machinery, among other technologies.

Electrochemical plating is offered by Ouneva and Valukumpu.

Powder coating

Powder coating is a surface treatment method that provides effective corrosion protection and a refined appearance. It is well suited for metallic, electrically conductive components. In the coating line, powder paint is sprayed onto the surface of the part and then melted in an oven to form a smooth protective layer. Our powder coating line is designed to allow automatic chamber painting or manual application for more complex products. Challenging components include enclosure-like shapes, where achieving an even coating inside typically requires either human or robotic reach.

Our powder coating expertise can be found at Ouneva and Top Speed.
