Cleaning

Cleaning surfaces...

removal of rust and forging shapes at metal surfaces

removing of moulding material residue at castings

removing of tempering colours, e.g. on stainless steel

The use of the right "cleaning deflashing media" always conforms
to the demands of the finally wished kind of surface.

The following composition can't be seen as universally valid,
but as starting point.

Basic material:	Blasting abrasive to take:

Fe - casting Fe - metals	Steel shot VERA GS-R (spherical) Steel grit GS-K (angular) Steel grit angular Chilled iron grit DIAMANT ¹ Malleable shot and grit THERMODUR ¹

Nonferrous casting Nonferrous metals	Steel shot made of stainless steel Light metal abrasive GRANAL Glass beads Glass grit Ceramic beads High-grade corundum white and pink Electro corundum NK I and NK II Duroplast MB ² Duroplast MC ² Kernel and shell granule ² Corncob granule ²
Materials such as wood, plastic, glass, etc.	Glass beads Glass grit Ceramic beads High-grade corundum white and pink Electro corundum NK I and NK II Special blasting corundum ³ Duroplast MB ² Duroplast MC ² Kernel and shell granule ² Corncob granule ²

¹ = should only be used in air-blast systems. The use in wheel-blast systems is only conditionell
meaningful, and because of the increased wear of the machine not advisable
² = should also be used only in air-blast systems
³ = only clever, when eventual residues don't matter on Fe-particles
