Products Description
Sandblasting glass balls have chemical stability, high mechanical strength, and hardness. They can be blown onto the surface of objects by compressed air, and can also be used to compress glass, rubber, plastic, metal castings, or compression molds. The spray ball helps to reduce the elasticity of the surface material and improve the wear resistance.
