Through continuous optimization and development of the process, shell mold casting can not only meet the strict requirements of modern industry for the accuracy and quality of castings, but also adapt to diverse and complex market demands.

[0003] During the shell making process of precision casting, it is necessary to ensure the drying of the shell mold. However, it is relatively difficult to dry the castings with slender hole structures during the shell making process. Often, the outer surface has been dried while the inside of the holes is still wet. Although solutions such as using ceramic cores can avoid this problem, the cost of ceramic cores is high and they are not suitable for small batch production. Summary of the Utility Model
