Shock Absorbers
ANKOR Hard Chrome Processes are OEM approved and meet the specification of the major Shock Absorber OEMs and Tier 1s, in this safety relevant application.
The piston or hollow rod of automotive shock absorbers is plated with an average of 15 µm to 30µm micro – cracked Hard chrome for wear- and corrosion protection in combination with their low friction requirements.
ANKOR chemical solutions meet the present and future demand of the industry for high yields, lowest cost per part, long term planning security and ELV compliance.

Zero Discharge Hard Chromium Plating
The industry is moving away from conventional “open tank plating systems” due to the increased emission regulation and higher workplace safety standards.
ANKOR GAMMAT is a zero discharge plating plant, designed to meet present and future regulations on Cr(VI). The chemistry remains in a closed pipe system and plated piston rods are suitably cleaned removing Cr(VI) residues before they are unloaded from the cell. ANKOR GAMMAT is one of the safest plating plants in the world. The system can be integrated in most industrial situations and makes plant approval much easier.
ANKOR Hard chrome process additives are designed for single component replenishment and therefore increase process capability and yields.
