Our Company
Chrom-Müller Metallveredelung GmbH is a certified electroplating and surface finishing company based in Oberndorf am Neckar (Baden-Württemberg). Founded in 1946, the company offers a broad range of coating processes: electroless nickel, phosphating (zinc, zinc-calcium and manganese as barrel or rack processing), anodizing, chromating/passivation, stainless steel passivation, electropolishing, pickling, sandblasting as well as derusting, heat treatment and printing in combination with coating processes. Materials treated include steel, iron, stainless steel, aluminium, copper alloys, cast materials, die-cast zinc and magnesium. Customer industries include the automotive industry, aerospace and medical technology, alongside general SMEs and large-scale industry. All process steps are accompanied by laboratory analysis – from wastewater analysis to part measurements based on representative samples.
