Perfect look, deburred and with a good grip. This is how one could describe the surface of the components leaving our stainless steel bead-blasting equipment. We use this inexpensive blasting variant for smaller components (welded constructions) up to 1.2m length. The welded joints are then freed perfectly from oxides and discoloration.
Only components made from stainless steel are blasted. Large components are blasted with glass beads due to the low mechanical influence on the metal surfaces (less distortion). When blasting with glass beads, the surface is matter than with stainless steel grit blasting.
The glass bead blasting processes we employ work very cleanly (with no risk of blasting material contamination). The alteration of sheet surface is very low.
Corrosion tests at the Federal Institute for Materials Research BAM, Berlin, have shown that the stainless steel components blasted in this way are always the best performers.
We have 3 large blasting chambers:
For example, housing, containers, claddings or decorative elements can be blasted. Very fine, delicate glass beads act as abrasives with which an optimum surface can be achieved.
It is important to elaborate filtering of the blasting material which has multiple reusability. For example, oxides and normal steel residues that would otherwise go back into circulation are safely removed. This has always been a problem for older equipment and can cause rust stains. Therefore, abrasive blasting with stainless steel material can be problematic: Here, the CrNi blasting material is always magnetic itself due to deformation martensite, so that the blasting material for reuse cannot be freed from oxide residues with a magnetic separator.
The glass bead blasting is particularly suitable to produce quickly and consistently clean surfaces in nooks and crannies of weldments. Even larger surfaces on thin sheet metal can be blasted clean, as the fine glass particles act abrasively, but do not strike the surface as hard (hammer effect) as stainless steel grit blasting, for example.
