Development of new products based on new coating systems and complex PVD technologies under scalable conditions (up to a coating width of 500 mm)

Typical substrates

  • single and double side coating of metal, plastic, glass or ceramic sheets with a maximum dimension of 500 × 500 mm.
  • coating of metal strips with a maximum width of 300 mm and a maximum thickness of 1.5 mm

Task spectrum

Production of large area coatings:

  • for special tests
  • as pilot production of small series for Fraunhofer FEP customers
  • for sampling at the end customer
