Coated Films

To create a top-class surface finish

Thermoforming

of coated film materials

In addition to their use for interior items, plastics are increasingly being used on the exterior of vehicles. Colour-coated film materials can be used to substitute complex coating processes.

The goal is to create a top-class surface finish. This is done by using a positive highly-polished vacuum-capable thermoforming tool to form the components in clean-room conditions. The subsequent back-injection or back-pressing process provides the required dimensional stability.

Kiefel ensures optimum compatibility for the entire process sequence used in the thermoforming of coated film materials:

  • Tool configuration with shrinkage rate detection
  • Thermoforming tool
  • Cleaning technology for film material
  • Clean-room technology
  • Thermoforming technology

Possible applications

In the interior:

  • Automotive interiors increasingly incorporate designer-style decorative elements in doors and instrument panels. This involves the three-dimensional forming of thin ABS film with compressed-air support. Depending on the surface of the ABS film, it is possible to produce an aluminium or wood-look design. A subsequent back-injection process gives the component its dimensional stability.

 

In the exterior:

  • Forming of roof modules
  • Forming of wing elements
  • Forming of various hood and cover elements
  • Forming of bumper bars and other body elements
