Mechanical production

Our focus and experience in this area rests on 130 years of history in the precise construction of gear units. Core areas of expertise include toothed components such as gears and shafts, but also assemblies, which we produce from the individual components up to the assembly using our complex tooling machines. In doing so, we draw on our extensive experience to produce components with the highest precision and reliability – as well as outstanding quality. Plus, we also cover a broad spectrum of parts, starting from batch size 1. This requires extensive experience during planning as well as precise machining down to just a few micrometers.

The RENK Group is a certified company according to DIN – ISO 9001:2008 and DIN – ISO 14001:2004 + Cor 1:2009. We have implemented an MSA (manufacturing survey agreement) with DNV. Based on the products we offer, we are monitored by classification bodies working on behalf of the end customer in manufacturing and production (e.g., ABS, BV, GTB, DNV, GL, LR, RINA, etc.).

Our laboratory dedicated to analyzing and documenting material specimens via tensile and notched bar impact testing as well as CHD and NHT measurements prepares and evaluates micrographs.
