Precision casting, which can be called investment casting for short,
1. Precision casting, is there any other name for it? Can it be used to produce more sophisticated and complex castings?
Its short name is "investment casting", and its English name is "precision casting". In addition, from the property point of view, it belongs to the special casting, rather than ordinary casting. In the specific application, there are many, for example, used to cast some more sophisticated and complex castings. So, on question two, the answer is yes.
2. What can be summarized as the process flow of precision casting?
The process of precision casting, if summarized, is five parts: wax pressing, shell making, pouring, post-treatment and inspection. Among them, pressing wax is including pressing wax, repairing wax and group tree these three. And shell, is hanging sand, hanging pulp and air drying these three. Its post-treatment includes sandblasting, shot blasting, correction and pickling, etc., and in the inspection, there are four wax inspection, initial inspection, middle inspection and finished product inspection.
3. Investment casting in precision casting, is its development prospect good?
Investment casting in precision casting. With the development of investment technology, it can be used to make both small and large castings. Its size in the casting, can reach 2 meters, in the casting wall thickness, thin wall type can reach 2 mm. In addition, the geometric tolerance and surface roughness of castings have been greatly improved. So, to sum up, its development prospects are very good.
