COATING  PVD and DLC coating of molding and cutting tools and parts
COATING

We specialize in coating of forming tools with PVD, DLC and diffuse coatings.

 

PVD coating is a surface treatment of mostly metal parts with a coating thickness of 1 - 10 micrometers. PVD coating takes place in a vacuum chamber with maximum parts dimensions of D450 x 700 mm. Company Šlechta a.s. uses pulse magnetron sputtering technology to maintain maximum surface smoothness of parts and forming tools.

 

DLC coating

We apply DLC coatings on machine parts, plain bearings and tools. DLC coatings are used to reduce friction, protect the tool against adhesive and abrasive wear as well as effective corrosion protection. We have experience with serial and piece production.

 

PVD coating

We specialize in coating of forming tools and increase of the productivity of cutting tools. We coat dies, molds, broaching and rolling tools designated for forming of metals, plastics and ceramics. We coat molds and cores for injection molding up to 250 kg.

 

Diffuse coatings

These coatings increase the hardness of highly polished surfaces up to 1600 HV. This increases resistance to abrasive wear and scratches. Thick diffusion layer up to 70 µm in the depth of steel does not change the final dimensions of the parts. This surface treatment is repairable by welding.
