About Süss Oberflächentechnik
Süss Oberflächentechnik GmbH was founded in 1950 and has been owner-managed ever since. At its Wetzlar location, the company operates two facilities, an electroplating plant and an anodizing plant, and finishes metal components for commercial customers. On aluminium, the company produces functional passivation layers as well as decorative anodized finishes, which can be dyed or executed in two colours on request; in electroplating, steel, stainless steel and brass are copper-, nickel- and chromium-plated, supplemented by the special processes of black chrome and blue pickling. For pretreatment, mechanical blasting processes with two centrifugal shot-blasting machines and one glass-bead air-blasting system as well as chemical pickling and brightening processes are available. The company offers dimensional-accurate coating with fit tolerances from 15 µm, advises on material selection, design, high-volume production and logistics, and works exclusively for commercial customers. Customer ratings from optics, medical and dental technology, automotive, aerospace, metrology and electronics range from 97 % to 105 %, according to the company.
