Hard chromium-plating

Hard chromium-plating is a galvanic, i.e. electrochemical, process. The electrolyte (consisting of water, chromium anhydride and sulphuric acid) is maintained at a constant temperature of approx. 54 °C in an acidproof-lined tub. Corresponding catalyst salts may be added to the electrolyte, depending more

Cylindrical grinding / Polishing

Cylindrical grinding - machining to achieve maximum precision. Precision grinding achieves both a defined surface quality and compliance with ultra-precise tolerances. Even grinding prior to plating is crucial to quality - a matter of course thanks to our know-how, our many years of experience and more


By means of specific heat-treatment, the ductility for chromium-plated workpieces can be influenced. Thanks to external initial heat application, the employment of workpieces in the installation or machine is possible without causing delay in production (of dry cylinders, for example).
