Printing / foil industry

Hard chrome from matt to mirror finish

Various surface qualities are required in the printing and foil industries. Rough matte chrome surfaces have an optimal grip, which improves the conveyability of feed rolls. If, on the other hand, a high-gloss surface is desired, we process the hard chrome surface up to mirror finish. In general, the hard chrome layer is characterized by its anti-adhesive properties, which prevent “sticking” or “caking” on the rollers.

The optimum surface quality

Matte hard chrome

In order to achieve a structured surface, the workpieces are blasted before the coating process. Blasting creates the specified peak-to-valley height. After the surface finishing, the components have a structured hard chrome layer and stand out visually through a matt surface. Via the defined peak-to-valley height the grip of feed rollers can be controlled for example. Learn more about our blasting process.

Mirror finish

With the Superfinishing procedure, a surface quality up to mirror finish can be created. Very fine Finish tapes (up to 3 µm) are used for this purpose. Mirror finish is required if the use of the component requires an absolutely homogeneous, clean and smooth surface. Learn more about the superfinishing process.

Properties of the hard chrome layer:

  • Layer thickness: 0.003 to 0.500 mm
  • Hardness: > 850 HV 0.1
  • Roughness: Rmax < 0.1 μm to Rz 70 μm
  • lead and cadmium free (RoHS compliant)
