What is the difference between shot blasting and sand blasting process?

Shot blasting and sandblasting both can play on the workpiece to achieve the function of cleaning and decontamination

so that prepare to next step which is to ensure that the roughness of the next step and some for consistency to the workpiece surface.

Shot blasting has to strengthen effect on the workpiece while sand blasting is not obvious.

Generally, steel shot for small steel balls is used by shot blasting and quartz sand for sand blasting.

According to different requirements, use these shot materials. Precision casting uses sand blasting and shot blasting process almost every day.

1.Surface de-rusting and descaling are the main functions of sand blasting, such as heat treated parts, while the role and function of blasting are more:

not only in addition to rust, oxide skin, but also improve the surface roughness, remove parts machining burrs, eliminate parts of internal stress,

reduce deformation after the heat treatment, improve parts surface wear resistance and compression ability etc..

2.The range of products used in shot blasting is more extensive, such as castings, forgings, parts after machining, parts after heat treatment, etc..

3 Sandblasting is a main manual operation, while shot blasting is automatic and semi-automatic more.

4.Steel shots and iron pills used for shot blasting is not the true sense of the bill, exactly it is small or small steel wire rod,

after a period of time it looks like balls; and the so-called sand for sandblasting is the river sand, and is not different from building sand,

the sand used for sandblasting goes through sieve with less mud and specific grain size. Of course, some industries are also different,

such as shipbuilding industry uses real steel shots and quartz sand (not sand).

5. Pills and sand pills are generally spherical, a class of particles is without edges and corners. Such as steel cut wire; sand refers to the

angle of sand, such as brown corundum, Bai Gangyu, sand etc..

6.Jet and spray use compressed air as a power make sand or pellet material sprayed to the surface of the material to achieve clearance

and a certain degree of roughness. Throwing is the method of drawing the centrifugal force of the pill at high speed to impact the surface

of the material to achieve clearance and a certain degree of roughness.
