Glass Ball and Steel-Grit Blasting

Blasting is one of the most important processes to produce even dull-finished or satin- finished surfaces before electroplating or anodizing. Here, glass-ball blasting with ball diameters of approx. 70-100 µm is the most frequently used process for decorative aluminium surfaces. Depending on the requirements and purpose, it is suitable also for steel, stainless steel and nonferrous metal.

In particular, camera housing and objective rings and also stainless-steel products and aluminium handles, such as those illustrated here, acquire their attractive appearance in this process.

Apart from glass-ball blasting in a continuous operation and by means of automatic rotary tables and manual installations we also offer steel-grit blasting in the automatic centrifugal jet machinery as pre-treatment for scaled or welded steel parts and castings.
