Cutting-edge technology and streamlined paths for the perfect know-how transfer.

At our headquarter in Kernen, close to Stuttgart, Germany all of our disciplines are housed under one roof. This enables us to respond quickly and with maximum flexibility. In our development process, we simulate the flow properties of the plastic within the mold to get the best out of the material. The Jacob laboratory can test all our products to the core - even under some customer specific environmental conditions.  The turning and plastic technology departments are complemented by the in-house tool shop and mold making: short paths for quick project realisation. A special team is dedicated to develop and produce non-standard customized solutions.
