Shot Blasting Machine
We provide high quality CNG Shot Blasting machine.
Our shot blasting machine can be used to remove burrs, diaphragms and rust, which may affect the integrity, appearance, or definition of parts of the object. The shot blasting machine can also remove the contaminants on the surface of a partially coated surface and provide a surface profile that increases the adhesion of the coating to achieve the purpose of strengthening the work piece.
Principle of Shot Blasting
Shot blasting is a cold treatment process, which is divided into shot blasting and shot blasting strengthening. Shot blasting, as the name implies, is to remove the surface. Shot blasting is also the name of a mechanical surface treatment process. Similar processes include sand blasting and shot blasting. Impurities such as oxide scale improve the appearance quality. Shot blasting is to use the high-speed moving projectile (60-110m/s) flow to continuously impact the surface of the strengthened object and invade the target surface and surface layer (0.10-0.85mm) during the cyclic deformation process. The following changes have occurred: 1. The micro structure is modified; 2. The non-uniform plastic outer surface layer retains compressive stress again, and the inner surface layer generates residual tensile stress; 3. The outer surface changes (Ra Rz). It can improve the fatigue resistance of materials/parts to prevent fatigue failure, plastic deformation and brittle fracture, and improve fatigue life.
Advantage of shot Blasting Machine
It can better remove the rust and splash on the surface of steel structure components.
It can make the surface of the steel structure member produce a certain degree of unevenness, increase the friction coefficient of the member (mainly used for high-strength friction bolts) and the adhesion of the paint.
By our shot Blasting Machine, by the control of PLC system, it can be achieved that The thickness of the abrasive, the size of the compressed air pressure (that is, the linear velocity of the shot), and the shot blasting time can be adjusted to obtain different shot blasting finishes and cleaning qualities.
