Wuxi IDEAL Machinery Manufacturing Co., Ltd., the manufacturer of the shot blasting machine introduced to you the reasons for the peeling of the shot blasting machine?

The manufacturer of the shot blasting machine introduced to us the causes of peeling after shot blasting?

Features: After shot peening, the surface of the casting will show a thin layer of skin, which can be easily removed by hand, and the size, area and orientation are not fixed. This phenomenon is called peeling after shot blasting.

Cause:

1. The casting is not compacted and has casting defects such as cold shut, delamination, bubbles and poor alloy flow fusion on the surface.

2. The steel shot blasting speed is too high.

3. Shot peening time is too long.

4. The hanging method is unreasonable, unstable, and collides with each other.

5. The shape and quality of steel shot are poor and not smooth.

6. The steel shot contains sharp magazines.

Cleaning method:

1. The casting surface is dark. Adjust the die casting process parameters or equipment parameters of the shot blasting machine.

2. Properly reduce the shot peening speed of the shot peening machine.

3. Properly reduce the shot peening time.

4. Select a reasonable hanger to ensure that the casting is fixed during the shot peening process, and select a special fixture if necessary.

5. Purchase steel shot with regular shape.

6. Select or replace steel shot.

The shot blasting machine technology is a combination of the surface and strengthening of the shot blasting machine of metal sheet materials. It has been used in the production of thin shell structures such as aircraft wings and fuselage. The U.S. Boeing aircraft has selected the shot blasting and shaping technology, which not only saves the large press, but also reduces the production cost. Together, it has also advanced the strength and rigidity of the thin shell structure, which has played an important role in improving the load function of the aircraft.

The application of shot blasting technology is not only the processing of the above-mentioned metal materials, but also the processing of non-metallic materials. For example, cutting the burr of various rubber products and plastic products is a low-power and labor-intensive operation. Now, shot blasting equipment with refrigeration equipment is used to freeze and embrittle various rubber products at low temperature, and then bear shot blasting and blasting in the shot blasting equipment, and the burr is easily removed. Phenolic plastic products are shot blasted with walnut skin,

It can remove burrs without damaging the surface roughness of its parts; After the transformer assembly, some remaining thread ends or other unnecessary sundries should be removed, and shot blasting made of walnut skin can be used to effectively remove them. In addition, in the maintenance of modern airports and expressways, it is necessary to clean the old cement on the ground before joining the new cement layer. The special mobile shot blasting equipment is selected to carry out the ground blasting to obtain the appearance with high bonding strength. The construction power is high, which can effectively reduce the construction cost. New building materials,

For example, the shot blasting process has been used to add the appearance effect of the block; The marble and other stone industries have initially selected the shot blasting process to gradually replace the traditional burning method to improve the yield and surface finish effect. Some molds are cleaned by shot blasting or sand blasting, and some are cleaned by dry ice blasting.
