About DOJ Metalltechnik GmbH
Who we are
Precision in metal — your partner for complex components and contract manufacturing Who we are DOJ Metalltechnik GmbH is your specialized service provider for sophisticated metal processing. We combine years of experience in machining with the latest sheet metal processing and welding technology. Our focus is not only on the finished part, but on process reliability and on-time delivery for your production. Our range of services — everything from a single source: -CNC machining: high-precision turning and milling of individual parts up to small series. -Special discipline of groove drawing: We produce precise dowels and inner profiles where others stop. -Sheet metal processing & laser cutting: State-of-the-art laser and folding technology for complex geometries. -Certified welding: Professional joining technology for resilient components. Why DOJ Metalltechnik GmbH? 1. Complete production: We take care of the entire process — from raw material to lasering and machining to the finished welding assembly. This saves you coordination effort and logistics costs. 2. Flexibility & speed: Thanks to our flat hierarchies, we respond quickly to short-term inquiries and secure your supply chains. 3. Quality without compromise: We see ourselves as a partner in mechanical engineering.
