Blast machine is a kind of mechanical equipment have the use of compressed air as its power, spraying different kinds of abrasive materials (metallic and nonm etallic) onto the surface of workpiece for impact grinding, for get rid of foreign matters, dithered color and oxide layer. At the same time, it shall can be used for roughening of the surface and for increasing of the superficial area. Through so doing , the adhesion of the coating can be improved and make the coating producing the strongest acid and alkaline resistance properties for upgrading coating quality and decreasing of residual stress on the surface of the basic material and for increasing the surface hardness of the basic material.

    The blast machine of XINYE SPARY COMPANY have complete function, reasonably structured, easy to operate and maintain, it can be used in any surroundings，and the grade of workpiece cleaning is Sa2.5-Sa3.0.
