Make it unique

In order to truly assess a product's aesthetics in the early stages of product development, it is absolutely worthwhile to build a prototype with a high-quality finish. Using various finishing techniques, we can match or surpass the quality standards of the final product.

Surface treatment and Decoration

We offer endless finishing possibilities including:

  • Painting: soft painting, texture painting and high gloss painting
  • Laser texturing, machining and etching
  • E-coating (KTL), Electroplating and anodizing
  • Flocking
  • Galvanic chrome plating
  • Metallization and PVD-coating
  • And many more...


Ready to install

Besides the production of separate parts, we can also take care of the assembly of an integrated module or even a full product. We are especially skilled in:

  • Complex assemblies with multiple options, e.g. bumper facias and door panels
  • Functional lighting modules including PCB’s


  • Vibration Welding (friction welding)
  • Hot plate welding (mirror welding)
  • Ultrasonic welding

Industrial Gluing

  • For all types and combinations of plastics, including surface preparation
  • Metal and plastic bondings
  • Adhesive tapes and kit
