Sand blasting process of prototype model

- Apr 04, 2018-

Prototype after the machine processing out all need to do some surface treatment technology, can make the prototype effect is more good-looking, on the surface of the following is sand blasting process, after sandblasting surface have a layer of sand grain effect, increased administrative levels feeling, make hand samples look more upscale and perfect.

Sand blasting technology used in compressed air powered, form a high-speed jet spray is expected to shoot to need to deal with surface of workpiece, the surface changes, due to the abrasive effect on impact on the surface of the workpiece and cutting, make get some cleanliness and different roughness of workpiece surface, make the workpiece can improve the mechanical properties of the surface.

Spray: copper ore, quartz sand, carborundum, iron sand, sand, etc., the prototype sandblasting is quartz sand.

Sandblasting can choose between different roughness, and no other process can achieve this.Manual polishing can be made out of wool, but it is too slow. The cleaning of chemical solvent is too smooth to remove the coating.
