Shot blasting is the use of a high-speed rotating impeller to throw small steel shots or small iron shots out of the surface of the part at high speed, so the oxide layer on the surface of the part can be removed. At the same time, the steel shot or the iron shot hits the surface of the part at high speed, causing the lattice distortion of the surface of the part to make the surface hardness increase. It is a method for cleaning the surface of the part. The shot blasting is often used to clean the surface of the casting or to strengthen the surface of the part.
