The stainless steel molding is based on the requirements of the casting process and is based on the determination of the molding method and the preparation of the molding material. The accuracy of investment castings and the economics of the entire production process depend primarily on this process. In many modern foundry workshops, modeling and making cores have been mechanized or automated. Commonly used sand molding core-making equipment includes high, medium and low pressure molding machines, air punch molding machines, box-less injection molding machines, cold core box core machines and hot core box core machines, and coated sand core machines.
