Our special-purpose machinery expertise
In special-purpose machinery engineering, we have been realizing customized assembly systems for many years for demanding assemblies such as injection components, rollover protection systems, vehicle keys, antenna modules, accumulators, pumps, as well as power and control electronics. We implement innovative solutions ranging from standalone manual workstations to fully automated assembly lines. Our systems are designed to flexibly adapt to varying production volumes and levels of automation.
Numerous successfully executed projects in the field of mechatronic, electronic, and hydraulic assemblies provide us with the experience required to reliably master even complex assembly processes. Already in the early project phases, we support you in designing process-oriented assembly concepts and use simulations and virtual commissioning to validate and optimize systems at an early stage. You benefit from a well-coordinated team that translates your requirements into a tailored and future-proof production solution.
