Company profile

Since the Hartchromwerk Brunner AG company was founded in 1965, we have been specialising in technical hard chromium-plating and have become a worldwide supplier offering maximum precision. The experience which we have gained over the course of the years has now long been incorporated as day-to-day know-how and the infrastructure which has been permanently expanded has become the natural equipment of choice allowing us to achieve best possible results.

Our building services management system which is constantly updated in line with the most recent state of the art allows us to treat the environment responsibly and also protect natural resources.

Thanks to our workforce comprising over 120 motivated and well-trained staff, we are prepared at all times to solve your problems, from the individual part to large-scale production.

Hartchromwerk Brunner offers the all-inclusive carefree package from Switzerland, from the partial hard chromium-plating to the complete manufacturing.

Electroless nickel plating

Electroless nickel plating is a purely chemical process, i.e. a process not involving external electrical current. Nickel is deposited wherever the workpiece comes into contact with the electrolyte. The deposition principle is based on the potential differences between metal and electrolyte. The process more

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


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). For chemically more

Cylindrical grinding

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
