Coating
We specialize in coating forming and cutting tools with PVD, DLC and diffusion coatings.
PVD coating
We provide surface treatment of mainly metal parts with a coating with a thickness of 1 - 10 micrometers. PVD coating takes place in a vacuum chamber with maximum part dimensions of D450 x 700 mm. We use highly productive pulsed magnetron sputtering technology to maintain maximum surface smoothness for parts and forming tools.
We coat:
- dies
- moulds
- broaching and rolling tools for forming metals, plastics and ceramics
- moulds and cores for injection moulding machines up to 250 kg
DLC coating
We apply DLC coatings to:
- machine parts
- plain bearings
- tools
Advantages of DLC coatings:
- reduce friction
- protects the tool against adhesive and abrasive wear
- protects against corrosion
Diffusion coatings
Diffusion coatings increase the hardness of highly polished surfaces up to 1600 HV. This enhances resistance to abrasive wear and scratch resistance. A thick diffusion coating up to 70 µm deep into the steel and does not change the final dimensions of the parts. This coating is repairable by welding.
