Do Dongguan precision castings need pickling or use water-soluble cores

Do Dongguan precision castings need to be pickled or use water-soluble cores?

1. Can precision casting be regarded as thin-walled castings?

Precision casting is one of the castings. Its shell is preheated at high temperature, and if the pouring speed is allowed to be slow, it can be made into thin-walled castings. Therefore, in this question, its answer is that if it is not iron, it can also be produced by the process of die casting.

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

As far as precision casting is concerned, water-soluble cores can be used for mold cores, but there are also special requirements. Generally speaking, if demolding cannot be performed on the casting structure, then a water-soluble core can be used on the mold core to achieve a good demolding effect.

3. In the manufacturing process of precision casting, is it necessary to pickle this process?

This sentence, from a professional point of view, is based on the actual situation. If there is dirt or oxide scale on the surface of the casting, then pickling must be carried out to make these removals clean, so that operations such as passivation can be carried out. No need to proceed. Therefore, this question cannot be answered well, because it depends on the actual situation to make a decision.

For precision casting, the above problems are very important and basic, and they are not available to the predecessors. Therefore, it is necessary to understand and give the correct answers so that everyone can know how to deal with them smoothly, so as to improve this The application function of this kind of castings has achieved good economic benefits.
