PRETREATMENTS FOR SURFACE REFINEMENTS

methodprecedure - change of surfaceapplications
ball polishingmechanical-chemical polishing process
A polished surface - almost like chrome is caused by striking the ground of material with a hard medium (balls of stainless steel) with the spezific form of this medium an eben surface will also be achieved in very narrow radii.
the process is applicable to aluminium and similar soft materials
trowalisieren(parts up to a size of max. 150 x 300 x 300 mm - the volumetric capacity is 800l)
the several parts will be processed in ahorizontal-belt-workpiece-dryer or a round-hutch-granulate-dryer
gentle and even flash-removal of the workpiece
glass-bead-blasting
ceramics-bead-blasting
the workpiece is blasted with glass-beads or ceramics-beads through nozzles for parts with high optical demands, but also as preparative for chrome-plating and similar processes
sand blastingcontaminations (like scales, casting skin or similar) are removed sparingly.
Plants up t0 5.000 x 5.000 x 8.000 mm
ideal cost saving process before new coatings, varnishing, chrome plating and any similar processes
