Plating
We offer two kinds of plating possibilities for metal products and components. Plating is done to achieve different protective and visual features for the product. Electrical conductivity can also be achieved with plating.
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
An excellent protection against corrosion is achieved with powder coating. Powder coating can be applied well with metal components that conduct electricity. Before the actual coating process, the items are washed, dried and a protecting pre-treatment agent is sprayed onto the surface. We use Bonderite and Surtec in our pre-treatment. Both of the agents have their own benefits considering different materials and manufacturing technologies like die-casted aluminium products or steel sheet metal items. After the pre-treatment, a plastic powder is sprayed onto the surface of the product using static electricity. Once the powder has been sprayed on the surface, it is melted in a special oven, creating a smooth protective layer on it. We typically use epoxy or polyester in our powder coating process. Sometimes a mix of the two is the best choice.
Our powder coating line has been built so that we can do the coating with automatic chambers and in case of a challenging item, manual coating can be applied. Challenging items can be enclosure-like items, where to be able to achieve an even surface, the process requires a human or a robot reaching inside.
Our powder coating expertise can be found at Ouneva and Top Speed.
