Precision molding method of precision casting

Precision casting includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, and lost foam casting. One of the more commonly used is investment casting, also known as lost wax casting: select suitable investment materials (such as paraffin) to make investment molds; repeat the steps of dipping refractory paint and sprinkling refractory sand on the investment mold, hardening the shell and drying; then Melt the internal investment mold to obtain a cavity; bake the mold shell to obtain sufficient strength and burn off the remaining investment material; cast the required metal materials; solidify and cool, and clean the sand after the shelling, thereby obtaining high Precision finished product. According to product needs or heat treatment, cold processing and surface treatment.
