Injection Pump Preparation Section
Established the Injection Pump Preparation Section. We began to expand our business beyond the company’s original field of development and production of electrical components. Today, we operate in various product areas such as powertrains, thermal systems, electronics and driving control & safety systems. Being able to deliver entire systems instead of single products gives us a competitive edge.
