ABSTRACT:
A reusable blasting medium of a thermoplastically processable polymer granulate filled with finely divided metal, the metal particles being coated with an adhesion promoter. The medium is suitable for the deflashing of cast metal parts, in particular ground, die-cast metal parts. The invention further relates to a process for the production of the blasting medium, including intimately mixing a polymer granulate of a commercial thermoplast, such as polyamide and/or polycarbonate, with a metal such as iron, copper, tin, stainless steel, brass, and/or bronze. The particles are coated with an adhesion promoter, the metal particles are in finely divided spherical form or a powder and the particle sizes are 0.01 to 0.5 mm. This mixture is extruded in the usual manner, preferably as a ribbon, and thereafter is reduced to the desired form and size. The blasting medium has the form of cubic particles of an edge length of 0.75 to 2.0 mm.
