Types and Processes of Metal Casting

② Special Alloy Casting can be divided into special alloy casting with natural mineral sand as the main molding material (such as Investment Casting, mud casting, casting workshop shell casting, negative Pressure Casting, solid casting, ceramic casting, etc.) etc.) and special casting with metal as the main casting material (such as metal mold casting, Die Casting, continuous casting, low pressure casting, centrifugal casting, etc.).

Metal casting processes typically include:
① Preparation of Casting Mold (containers that make liquid metal into solid castings), casting molds can be divided into sand molds, metal molds, ceramic molds, mud molds, graphite molds, etc. And permanent mold, the quality of mold preparation is the main factor affecting the quality of castings;
② Melting and pouring of cast metals, cast metals (cast alloys) mainly include cast iron, cast steel and cast non-ferrous alloys;
③ Casting treatment and inspection, casting treatment includes removal of foreign matter on the core and casting surface, removal of pouring risers, relief grinding of burrs and seams and other protrusions, as well as heat treatment, shaping, anti-rust treatment and rough machining.
