When deflashing metal die cast mouldings we are faced with the following dilemma: Fine metal blasting grit produces good surfaces but the deflashing ratio is poor, while heavier grades of metal grit do a good deflashing job but tend to mar the surfaces or even destroy delicate areas such as threads, slits, fins, hinged flaps etc.
Emsodur has been successful in developing a loaded deflashing/blasting media. Thanks to the binding of the load with the plastic media the media features a combination of abrasion resistance and a long life span equal to other non-filled Emsodur grades. It’s higher densitiy raises the kinetic energy considerably.
The possible applications in deflashing metal compression mouldings are thus essentially widened: High deflashing efficiency can either be combined with a gentle polishing effect or with no surface polishing effect at all.
It is also possible to mix our media with the blasting grit you have been using so far. This would raise the deflashing effect, whilst when choosing a finer grade metal blasting grit, the surface finish of the media blasted parts is improved.
