Shot Blasting Machine

Qingdao Puhua Heavy Industrial Group | Updated: Dec 02, 2015

Shot blasting machine main uses are as follows:
① shot blasting machine part surface compressive stress can improve their ability to fatigue strength and resistance to stress corrosion;
② shot blasting machine to correct the distortion of thin-walled parts;
③ shot blasting machine technology instead of cold and hot forming, processing of large thin-wall aluminum parts can not only avoid parts of the surface residual stress and compressive stress that can be obtained is good for parts. Should pay attention to is: shot blasting machine processed part temperature must not be too high, or compressive stress will disappear automatically in high temperature, thus losing the desired effect. They use temperatures up to parts of the material used for General steel parts about 260-290 ℃, aluminum parts only 170 ℃.
