High-tech as tradition The coating of surfaces is a long-standing tradition at Blösch. It was back in 1947 that Walter Blösch began to develop a special gold plating for jewellery and watches. The sheer superiority of this plating revolutionised the industry.
Blösch has been using vacuum technology since the 1970s to produce high-precision metallic and optical coatings. We respond to the changing market requirements by cutting-edge processes and continuous developments and improvements in pretreating, cleaning, handling and finishing. The great advantage of vacuum coating is that almost anything can be coated – which means that virtually every material can potentially be used as a coating. Blösch has developed its expertise over the years in the coating of sapphire, glass, precious metals, alloys, stainless steels, ferrous alloys, non-ferrous alloys, carbides, ceramics and cermets. In all cases the coatings are both decorative and functional.
