What are the basic requirements for the prevention of pitting on the surface of precision castings?

1. How to prevent pitting on the surface of precision castings?

If you want to achieve the above purpose, there are some preventive measures, which are as follows:

Measure 1: The quality of the materials used should be guaranteed, at least qualified materials should be used. Moreover, it should be carried out strictly in accordance with the process specifications and operating requirements, and there should be no wrong operation to avoid affecting the quality of the castings.

Measure 2: The selection of some auxiliary agents or additives should not only ensure good use effects, but also avoid various problems. Therefore, the amount and use of them should be strictly controlled without any deviation.

For this type of casting, the basic requirement is that the surface of the casting is clean and free of any defects, such as sand sticking, scale, flash, and casting nodules.

3. If a precision casting has bulging or iron leakage, is the specific cause related to the casting itself?

If a precision casting has bulging or iron leakage, the specific cause includes the casting itself. It may be that the mold shell is not strong enough or the adhesive used has problems. So, the answer to this question is yes.
