How to prevent pitting on the surface of precision casting hardware?

In this case, if you want to achieve the above purpose, then there are some preventive measures, which are as follows:

Measure 1: the quality of materials used should be guaranteed, at least qualified materials should be used. Moreover, it should be carried out in strict accordance with the process specification and operation requirements, and there should be no wrong operation, so as not to affect the casting quality.

Measure 2: for the selection of some auxiliaries or additives, we should not only ensure good use effect, but also avoid all kinds of problems. Therefore, we should strictly control their dosage and use, without any deviation.

2. Is there any difference between the casting method of precision casting and traditional casting method? In addition, what are the basic requirements for this kind of casting?

For precision casting, its casting method is precision casting hardware, so it is different from the traditional casting method. Therefore, the two are different. For this kind of casting, the basic requirement is that the surface of the casting should be clean and free from any defects, such as sand sticking, oxide scale, flash and casting tumor.

3. If there is bulge or molten iron leakage in precision casting, is it related to the casting itself?

If there is bulge or molten iron leakage in precision castings, the specific reasons include the casting itself. It may be that the strength of the mold shell is not enough, or the binder used is defective. Therefore, the answer to this question is yes.
