How to Avoid the Aluminum Die-casting Gets Blackened After Shot Blasting?



The reasons for blackened aluminum die casting parts after shot blasting are:

1. The dust removal is not done in the equipment during shot blasting;

2. There are oil stains, mold release and moisture on the casting surface;

3. Stainless steel pellets are not pure enough.



To prevent the aluminum die casting parts from blackening after shot blasting, here is some suggestion:

1. The shot blasting equipment must have a relatively complete automatic dust removal effect;

2. The surface of the casting should not be contaminated with oil, mold release agent, moisture or other impurities. If necessary, the casting should be washed and dried before shot blasting;

3. Purchase pure steel shots, if necessary, add 10 ~ 30% aluminum shots to increase the whiteness after shot blasting. The specific amount depends on the requirement of the parts.
