Detail of product
1. This product is made of borosilicate raw material by high-tech processing.
2.The product has high strength, good chemical stability and so on.  Shot blasting is the preferred medium.
3.Sandblasting and shot peening difference:  sandblasting abrasive speed is sprayed using compressed air to the workpiece surface, the purpose is to remove the surface oxide layer, rust, etc., in order to improve the surface appearance. Shot peening is a high-speed hard particles against the surface of metal parts, aims to improve the fatigue strength of the metal surface. Both processes use different tools. These two methods of media may be recycled.
