1. Precision castings, can they be thin-walled castings?

Precision castings, which are a kind of castings, whose shell is preheated at high temperature, and, if the pouring speed is slow, it is possible to obtain thin-walled castings. So, in this case, the answer is yes, and if it's not ferrous metal, it can be done by die casting.


2. Can water-soluble core be used on precision castings?

In precision castings, for the mold core, it is possible to use a water-soluble core, but there are specific requirements. Generally speaking, if the casting structure is not good for demoulding work, then the water soluble core can be used on the mold core, and then, to get a good demoulding effect.


3. Is pickling necessary in the production of precision castings?

This, from a professional point of view, is to see the actual situation, if the surface of the casting is dirty or oxide skin, then it must be pickling, in order to remove these clean, so that passivation and other operations, if not, do not need to be carried out. Therefore, it is difficult to answer this question, because it depends on the actual situation to decide.

For precision casting, it can be said that the above problems are very important and basic, at the same time, is also not in front of, so it is necessary to understand, and give the right answer, so that we know how to solve, and then, to improve the use of this kind of casting effect, get good economic benefits.
