The principle of JIS G3115 SPV355 steel shot

SPV355 steel shot blasting is the body of the motor to drive the impeller rotation (direct drive or use the "V" belt drive), by the effect of centrifugal force, the diameter is about 0.2 ~ 3.0 projectile (have pills for cast steel, steel cut wire shot, stainless steel, such as different types) into the SPV355 steel shot blasting surface, make the SPV355 steel shot blasting, the roughness of the surface reaches a certain make SPV355 steel becomes beautiful, or change the SPV355 steel plate welding tensile stress to compressive stress, improve the service life of the SPV355 steel plate.

Through improving all kinds of steel surface roughness, also raised steel subsequent paint film adhesion. Shot most of this process is almost used in mechanical field, such as shipbuilding and ship repairing, auto parts, aircraft parts, guns, tanks, Bridges, steel structures, surface glass, steel profiles, internal or external pipeline anticorrosion wall even road surface and so on industry.
