The Company
Who We Are and How We Work
As an owner-managed specialty machine builder based in Karlstadt, we develop and implement customized plant solutions. From the initial idea through design, control systems, and in-house manufacturing to on-site commissioning, we support our customers without lengthy handoff processes. Design, manufacturing, and assembly all take place in-house. This enables streamlined processes, direct communication, and full responsibility for the final result. Our customers in the automotive industry, semiconductor manufacturing, aerospace/defense, and medical technology need systems that not only function technically but also operate reliably in series production. We’ve got it covered.
