Surface Treatment: Sandblasting

         Sand blasting is a process that uses sand or iron particles sprayed at high speed to impact the workpiece surface, so as to improve some mechanical properties of mechanical parts and change the surface state.

        The process of sand blasting and shot blasting is similar, and the main difference is in the diameter of sand particles. The process is mainly used to improve the mechanical strength, wear resistance, fatigue resistance and corrosion resistance of parts. It can also be used for surface extinction, scale removal and residual stress elimination of castings, forgings and weldments.
