Join us in shaping the mobility transition!


KNIPPING KUNSTSTOFFTECHNIK represents over 60 years of successful family-owned business history. In our facilities in Germany, Hungary, and Mexico, we develop and produce plastic parts and assemblies, mainly from thermoplastics and thermosets. Our customers include renowned companies in the automotive and electronics industries.

One of our strengths is our constant redefinition and realignment. These strengths are particularly valuable in times of transformation towards e-mobility. One of the technologies that will play an important role in this transformation is the hydrogen PEM fuel cell. Advantages of the hydrogen PEM fuel cell include high ranges and short refueling times.

This has prompted KNIPPING to establish a new business division called KNIPPING NEW MOBILITY. The focus of KNIPPING NEW MOBILITY is on the development of Balance-of-Plant (BoP) components for the cathode subsystem of a fuel cell system. The primary focus initially is on developing a humidifier.
