Surface treatment
The treatment and finishing of surfaces of metal parts contributes to their protection and optimization. Whether semi-finisihed product or component, Wieland has a solution.
Every application has individual requirements - also with regard to the surface. We offer both standards, such as roughness or protective coating, but also special qualities or tin plating. However, our expertise also includes organoceramic thin films that meet different requirements through targeted modification with high-tech materials.
