1. Can precision castings be thin-walled castings?

Precision castings are among the castings where the molded shell is preheated at high temperatures. If the pouring is slow, thin-walled castings can be obtained. Therefore, the answer to this question is yes; if it is not a ferrous metal, it can be done by die casting.

2. Can water-soluble cores be used in precision casting?

For cast products, mold cores can use water-soluble cores but with specific requirements. Generally, if the casting structure is not suitable for demolding, water-soluble cores can be used on the mold core to achieve good demolding effects.

3. Is pickling necessary during the precision casting production process?

In this case, from a professional perspective, it is necessary to consider the actual situation. If the casting surface has dirt or oxide scale, pickling is needed to remove these for operations like passivation. If not, it is unnecessary. Therefore, this question is difficult to answer as it depends on the actual situation.
