About Gerhard Kummerfeldt Gerätebau GmbH

We are a certified welding company according to DIN 18800-7 "E" (advanced certificate) as well as the new standard EN 1090-1 EXC3.

The Gerätebau GmbH is a medium-sized manufacturing company, which originated in 1969 in the first company founded by Gerhard Kummerfeldt, Gerhard Kummerfeldt Feinmechanik.
The Value of reliability, precision, quality and on-time delivery counts today as much as it did in the past, and has led to a steady growth of the company over the years.
Expansion of the business and increasing space requirements asked for several moves into larger operating rooms, before in 1979, a separate, spacious new building in the Norderstedter business park Harkshörn was purchased.

In order to meet the growing demand for qualified staff and also to live up to our social responsibility, we train young people in the merchandising and commercial sector at our company. Today, Gerhard Kummerfeldt Gerätebau GmbH with its 35 highly qualified employees and modern equipped machinery is able to offer its customers a broad range of services in the following areas:

The DIN EN ISO 9001: 2015 certified quality management system quarantees the quality of the manufactured parts, assemblies or complete Machines and tools. This paired with our experience and the constant effort to support our customer in all matters of manufacturing and assembly with advice and knowledge, has led to an excellent reputation of Gerhard Kummerfeldt Gerätebau GmbH, of which we are very proud.

Quality is not just an empty phrase for us, but the first principle since the founding of the company.

From receiving basic materials to final delivery, all operations are fully monitored. This ensures that the tolerances, material and surface quality of the workpieces specified by the customer are met
According to customer sketches individual parts, series, subassemblies, housings, racks etc. are produced in our modern production halls.
