Door carrier plates

for the automotive and utility vehicle industry

Door carrier plates to integrate functional elements

Functionality, sealing of dry area, sound insulation, and weight reduction by using technical plastics.

Door carrier plates serve as supporting elements for door attachment systems, such as power windows, loudspeaker units, sensor systems, and many more. For this purpose threaded bushes for example are integrated in components already during injection molding or also in a downstream process step.

Moreover, door modules separate dry and wet areas by means of extruded 2-component sealing lips or applied multi-component foam sealants.

Our water shields offer additional protection against moisture for door attachment elements.

The integration of sound-absorbing additional components in or on function carriers is also part of our range of services and is done according to customer specifications.

To manufacture our components we use state-of-the-art technical plastics and can therefore achieve maximum weight savings and the highest safety standards.
