Usually, various projecting ashes of various type are used in Blasting engineering techniques that is common designation by Sand Blast and Shot Blast but product that produce at our company is producing mainly that is Soft Media among these.
This is media that is applying usually in advanced foreign each field of industry by special procurements abrasives that hardly influences on the subject surface and can do surface treatment softly.
that our company is Soft projecting calamity that is not informed well to domestic market yetspreads widely advanced overseas surface processing method of construction and is inexpensive doing localization and meet with customers by quality good product wish to.
Desire that encourage with a lot of guidances as wish to supply our company product exporting mainly abroad to domestic market that is not matured yet.
