Introduction to IDEAL002 and JPG shot blasting machines:

JPG type shot blasting machine is a casting equipment that uses the high-speed shot thrown by the shot blasting machine to clean or strengthen the casting surface. The shot blasting machine can simultaneously carry out sand blasting, core removal and cleaning of castings. Introduction to mechanical treatment technology of metal surface - shot blasting machine sends steel shot to a high-speed rotating disk, and uses centrifugal force to make the high-speed shot hit the surface of parts to achieve the purpose of polishing. This process is called shot blasting. The process of using compressed air to spray steel shot or glass shot onto parts to remove oxide scale and other dirt is called shot peening. Both of these processes can produce compressive stress on the surface of parts, and there is no silicon powder, which has little environmental pollution.

The main uses of JPG shot blasting machine are as follows:

1. Make the surface of parts produce compressive stress, which can improve their fatigue strength and tensile stress corrosion ability;

2. Correct the twisted thin-walled parts;

3. In place of the general cold and hot forming process, the forming of large thin-walled aluminum parts can not only avoid the residual tensile stress on the surface of the parts, but also obtain the favorable compressive stress for the parts.

It should be noted that the service temperature of shot peened or shot blasted parts should not be too high, otherwise the compressive stress will disappear automatically under high temperature, thus losing the expected effect. Their service temperature is determined by the material of the parts. For general steel parts, it is about 260-290 ℃, and for aluminum parts, it is only 170 ℃.
