The big shot blasting machine
Main Function:
- Make the parts surface compressive stress, can improve their fatigue strength and the tensile stress corrosion
- The distortion of thin-walled parts
- Instead of common cold, hot molding process, molding processing, not only can avoid residual tensile stress at the surface of the parts, and can obtain better compression stress for parts, should pay attention to is that the shot peening or blast temperature not too high, the use of the processed parts or compressive stress at high temperatures will disappear automatically, thus losing the desired effect.They use temperature is determined by the material of parts, for the average steel parts is about 260-290 degrees Celsius.
