Overview of Permanent Mold Casting with Bronze
Permanent Mold Casting is a metal casting process that uses reusable Steel molds (dies), ensuring consistent quality and tighter dimensional tolerances. In the case of Bronze Permanent Mold Casting, molten Bronze is poured into these precision-engineered Steel molds either by gravity or low pressure. The result is a dense, fine-grained casting with superior mechanical properties compared to sand castings.
