DONGRUN CASTING is one of the leading high quality gravity die casting parts china factory manufacturers and suppliers in China. We have customized high quality gravity die casting parts china factory made in China, welcome to check the quotation with our factory.
Internal features or external features that cannot readily be molded, can be provided in castings by the use of cores. Collapsible cores are made in bonded sand, plaster or ceramic materials are expendable. Separate equipment, termed a core box, is required for the production. Cores as located in core prints in the mold or die and these prints are formed as features of the mold or die. Permanent metal cores can be used in the gravity die casting process, especially pressure die casting for which collapsible cores are not currently suitable.
This preliminary consideration of the casting process has provided a basis for process classification according to the permanent or expendable nature of the pattern and mold
