Colored stainless steel sand blasting is using compressed air as the power, in order to form the most adjust injection will material (copper ore, iron sand, sea sand, quartz sand, gold steel grit) high-speed jet to the need to deal with the workpiece surface, make the appearance on the surface of the workpiece surface appearance or shape change, due to the abrasive impact to the surface and the cutting effect, make the surface of the workpiece for cleanliness and different roughness, make the workpiece can improve the mechanical properties of the surface, thus improve the fatigue resistance of workpiece, increased its adhesion between the coating and, extend the durability of the coating, but also to the flow of paint and decoration.

Compared with other cleaning processes (such as pickling and tool cleaning), sandblasting process has the following characteristics:
Sand blasting is the most thorough, the most general, the most rapid, the most efficient cleaning method.
Second, sandblasting treatment can be arbitrarily selected between different roughness, and other processes are unable to achieve this.
Manual polishing can play the surface but the speed is too slow, chemical solvent cleaning is not conducive to the surface for smooth coating adhesion.
Sandblasting mainly has the following applications:
(1) the workpiece coating, plating, workpiece bonding treatment.
Sandblasting can remove all dirt such as the rust skin on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece (that is, the so-called hair surface), and can be exchanged through different particle size of abrasive, to achieve different degree of roughness, greatly improve the work and coating, plating material adhesion.
Or to make the bonding piece bonding more firmly, better quality.
(2) cleaning and polishing the rough surface of cast and forged parts and the workpiece after heat treatment.
Sandblasting can clean up all dirt on the surface of casting and forging parts, after heat treatment (such as oxide skin, no dirt and other residues), and polish the surface of the workpiece to improve the smoothness of the workpiece, play the role of beautifying the workpiece.
Sandblasting cleaning can make the workpiece show uniform metal color, make the workpiece appearance more beautiful, to beautify the role of decoration.

(3) burr cleaning and surface beautification of machining parts.
Sand blasting can clean the small burr on the surface of the workpiece, and make the surface of the workpiece more even, remove the harm of burr, improve the level of the workpiece.
And sandblasting can be in the workpiece surface junction hit a small round corner, so that the workpiece appears more beautiful, more precise.
(4) improve the mechanical properties of parts.
After sandblasting, mechanical parts can produce uniform and subtle concave and convex surface (basic schema) on the surface of the required parts, so that the lubrication stains can be stored, so as to improve the lubrication conditions, reduce noise and improve the service life of the machinery.
(5) light decoration.
1. Polish various workpiece surfaces to make them more beautiful.
2, make the workpiece to meet the requirements of smooth and non-reflective, that is, to achieve a certain surface roughness.
For some special purposes of the workpiece, sandblasting can be optional to achieve different reflective or sub-light.
