FEATURES IN SANDBLASTING
 

Higher hardness

Strong cutting force

Good chemical stability, acid and alkali resistance

Iron-Free

Molds cleaning sandblast

Steel, copper molds cleaning, removal of mechanical scratches, removal of surface residues

Like mold release agent, sediment, etc. and repair of molds. It does not hurt the mold surface, ensuring mold accuracy.

Pre-treated sandblasting to increase surface adhesion before coating, painting, Teflon spraying, Metal spraying (aluminum, stainless steel), galvanizing, chrome, nickel, oxidation treatment, flaw detection...
