Hard chrome plating

One of the exclusive services we offer includes hard chrome plating for large format rollers, for instance for gravure cylinders, technical rollers, guide rollers, and much more.

We chrome plate steel, copper, and aluminum.

Among their many benefits, chrome-plated surfaces provide a significant value-added for trouble-free operation of gravure cylinders. Chrome-plating is generally also an effective protection against corrosion and wear.
Our portfolio also includes chrome removal and buffing, as well as surface treatment in the form of grinding and polishing operations.

Available sizes and processing geometries:

  • Ballenbreite bis 4.300 mm
  • Gesamtbreite bis 5.000 mm
  • Ballendurchmesser bis 650 mm
  • Face lenght up to 4,300 mm.
  • Overall lenght up to 5,000 mm.
  • Diameter up to 600 mm.

RZ values: up to <0.1µm
Concentricity and parallelism: up to 0.01 mm

Used and special-purpose machines - worthwhile alternatives

You want to remain independent and are looking for a cost-effective alternative to handle your production process in-house with your own machines? From the electroplating system to the measuring instruments, hsa offers a versatile range of used machines. Before reselling, we bring all our used machines up to date and adapt them to the production process of our customers. Do you have special requirements for a machine? Then a special-purpose machine from hsa is worth considering. This will be individually and flexibly tailored to your production processes. So none of your needs remain unfulfilled.
