Mechanical
Surface Treatment

GRONBACH relies on innovative surface treatments for decorative applications in the material, forming and joining technology of stainless metals such as stainless steel or aluminium. This makes the components more resilient, corrosion-resistant, heat-resistant and conductive. We use the following methods for the mechanical treatment of surfaces:

Brushing and grinding

With these machining processes, the material is removed manually or mechanically by appropriate abrasives and grinding movement in order to achieve the desired surface structure. The ground materials can then be finished in various colours, e.g. using the anodising process, and are protected against corrosion and scratching. Especially when brushing metal or aluminium – fine, dulled or textured surfaces can be produced for high-quality optics.

Blasting

By blasting, the surface treatment is carried out by different blasting media (shot blasting, sand blasting), which are directed onto the material at high speed, e.g. by means of air, liquids or magnetism. This results in a compaction of the material and at the same time the solidification of the surface. In addition, surfaces can be cleaned, machined, matted and finished using this process.

Polishing

The removal of thin layers of the surface removes the smallest burrs, particles, unevenness and impurities. This results in high strength, low adhesion and pure and shiny results of the material.

Additional information on our machining methods for mechanical parts and components as well as metal coatings can be found in our brochures, which you can order free of charge. In addition, our competent staff will be happy to answer any further questions you may have about our production technologies and our company network.
