Our coatings are the preferred coatings for machining, shaping and stamping processes, plastics technology and in all areas where tribological properties need improvement.

Our PVD coatings excel in the machining industry as a result of the following advantages:

Für den Anwendungsbereich Zerspanungstechnik zeichnen sich unsere PVD-Schichten durch folgende Vorteile aus:

  • Significantly longer service life
  • No material build-up on the cutting edges
  • Better heat removal through cutting chips
  • Increased cutting parameters
  • Dry machining possible
  • High speed cutting possible

Application-oriented recommendations can be found in our data sheet.

Shaping and stamping technology

Our PVD coatings excel in the shaping and stamping industry as a result of the following advantages:

 

  • Low tendency to material build-up
  • Significantly longer service life
  • No sticking and cold build-up
  • Optimization of the flow characteristics
  • Clean cuts and therefore less dressing needed for the work-piece. Reduced coefficient of friction and therefore reduction in the stamping and retraction forces.

Application-oriented recommendations can be found in our data sheet data sheet.

Plastics technology

Our PVD coatings excel in the plastics processing industry as a result of the following advantages:

 

  • Excellent wear protection
  • Protection of structured tools and protection against damage to finishes
  • Improved release properties
  • Faster filling & shorter cycle time
  • Reduced cleaning through reduction of plate -out
  • Increased production reliability
  • Improved surface quality of the plastic parts
  • Reduced distortion of the plastic parts

Application-oriented recommendations can be found in our data sheet.

Tribological coatings for tools

In the fields of tool and die making, machine and mold construction and the machining of aluminum, we favor TT®-DLC and TT®-C-DLC as tribological coatings.

TT®-DLC is a metal-free diamond-like layer of carbon and is deposited at low temperatures using the PACVD process. The combination of good wear-resistance and outstanding frictional and non-stick properties makes TT®-DLC coatings an ideal surface treatment for components and tools subject to high frictional forces.

TT®-C-DLC coatings are a sub-group of the amorphous, diamond-like carbon coatings (DLC – Diamond-Like Carbon). Unlike the majority of the commercially available TT®-DLC coatings, they are not deposited from gaseous hydrocarbons (e.g. acetylene or methane) using the plasma-activated CVD process (PACVD-Plasma Assisted Chemical Vapor Deposition). They are produced using the PVD process (Physical Vapor Deposition) by sputtering a carbon target. The addition of reactive gases during the coating process enables the hydrogen content and therefore the mechanical and tribological properties of the coating to be adjusted to optimize the properties for the application in question.

TT®-C-DLC coatings can achieve both a higher hardness and a lower coefficient of friction than the TT®-DLC coatings deposited by the PACVD process. The properties of TT®-C-DLC coatings are summarized in the table.

TT®-C-DLC coatings are normally deposited with a thickness of 1.5 ± 0.5 μm. Because of their properties, TT®-C-DLC coatings are readily used when manufacturing standard components.
