Sand blasting machine using general simple hand brush, sand cloth grinding and other methods, this is a kind of low cleanliness, the protection of the coating is only a little better than the untreated workpiece. Primary processing technology standards: the workpiece surface should be free of oil, oil, residual oxide scale, rust spots, residual paint and other dirt.

Cleaning level 1 also known as hand brush cleaning level. Automatic sandblasting machine is generally used for painting. Its technological disadvantage is manual rust removal, low efficiency, poor site environment. As a result, most of the companies that produce bulk shot blasting (SELECT) have chosen to do so. In the production of ordinary castings, sand blasting must be carried out to find the surface defects of castings, such as subcutaneous pores, slag holes, clay sand, cold isolation, spalling and so on. Metal (such as copper, lead, zinc) castings, such as aluminum (Al) alloy (melting point 660℃), copper alloy and other alloys surface cleaning, peeling (corrosion products formed by oxidation), found their surface defects, the main purpose is to remove the burr of die casting by shot peening, obtain the surface decoration effect, to achieve a comprehensive effect.

The strengthening effect of sandblasting machine equipment on decorative workpiece:

1. Decoration scope:

2. Product surface decoration (such as various tools);

3. Printing dies, stamping dies, pressing dies and stamping dies;

4. Surface finishing treatment of combined pipeline conveyor;

5. Carve patterns and words on the surface of products (such as glasses, crystal ornaments, etc.);

6. Maintenance of equipment (such as motors) after surface treatment;

7. Discolor the surface of the equipment parts;

8. Sculpture and other artistic works of surface treatment and support;

9. Remove mold surface defects;

10. Smooth and clean the surface of the mold.
