About Hans Heimerdinger Oberflächentechnik
Hans Heimerdinger Oberflächentechnik is an owner-managed company founded in 1985 in Pforzheim, specializing in the electroplating of metal surfaces. The core competence lies in the functional coating of micro parts with diameters from 0.05 mm, including complex-shaped components and selective partial coating of unpopulated elements. The service portfolio includes coatings of copper, nickel, nickel-phosphorus, bronze, silver, gold and gold alloys, rhodium, palladium, as well as passivation, passivation and electropolishing of stainless steel. The parts are coated by barrel processing, vibration technology or selective electroplating. Customers come from aerospace, medical technology, the automotive industry, IT and communications technology, renewable energies and research, with which the company collaborates. At the Esslinger Straße 20 site in Pforzheim, production, the analysis laboratory and administration are combined under one roof.

Additional services
Quality
A multi-stage quality management system accompanying the production process, with complete documentation, ensures coating quality. The in-house laboratory regularly analyzes the process electrolytes; metrology such as X-ray coating thickness measurement, SEM, EDX, whisker and climate tests are used.
