about this location
welcome to Kerpen

In 1960 the former AHC Oberflächentechnik GmbH was founded by Ulrich Reininghaus and Herbert Friebe in Cologne-Mülheim. Due to a very good order situation, the production capacities were quickly exhausted. A new, generously planned production site had to be built, and it was located in Kerpen in the Rhineland. Since January 2019 we officially belong to the Aalberts surface technologies group. Through regular investments and technical developments, the location has grown steadily.
Today, 150 employees refine technical components for around 3,000 active customers, primarily in the mechanical engineering and automotive industries. Standard processes are hard anodizing (HART-COAT®) and electroless nickel (DURNI-COAT®). Special features of the Kerpen plant are the SILA-COAT® 5000 process, an anodic dip coating to increase alkali resistance, and the HC large component plant. Large parts such as rollers, tubes, profiles or running rails for goods distribution systems are hard coated here.

applications
In our HART-COAT® production area, housings of all kinds are coated: for example valve housings, filter housings or blower housings for washing machines. Whithin the HART-COAT® large part plant, rolls up to 8 m long, pipes and profiles are hard anodized.
The DURNI-COAT® production range includes components such as coupling hubs, needles for carburettors, secondary rotors for compressors, pump parts for automotive air conditioning systems, technical springs or test rims.
In the SILA-COAT® area, products such as pump nozzles for filling stations, pistons for pneumatic cylinders as well as valves or even electric motor housings are coated.
