Radiator and brake ventilation

As a system developer for multi-component air guiding components, we are your competent partner.

Air ducts direct external air to the radiator and brake system and are usually installed in the front of the vehicle.

We manufacture these parts using multi-component injection moulding. The combination of hard and soft components ensures aerodynamics, stability and sealing to the surrounding components.
