Introduction to the Casting Industry
Casting is an industry with roots in traditional craftsmanship. There are many types of casting, which are conventionally classified by molding method into: ① Ordinary sand casting, comprising three categories: green sand (moist sand) casting, dry sand casting, and chemically hardened sand casting. ② Special casting, which can be further subdivided based on mold materials into processes using natural mineral sands/aggregates (such as investment casting, loam/clay mold casting, shell mold casting, negative pressure casting, full-mold casting, and ceramic mold casting) and processes using metal as the primary mold material (such as permanent mold casting, die casting, continuous casting, low-pressure casting, and centrifugal casting). Casting processes typically involve: ① Mold preparation (creating the container that transforms liquid metal into a solid casting); molds are classified by material (sand, metal, ceramic, loam/clay, graphite, etc.) and by reusability (expendable, semi-permanent, and permanent), with the quality of mold preparation being a primary factor affecting the final casting quality; ② Melting and pouring of casting metal (casting alloys), primarily involving cast iron, cast steel, and non-ferrous casting alloys; and ③ Casting treatment and inspection, which includes removing cores and surface debris, cutting off gates and risers, grinding away burrs and flash, as well as heat treatment, shaping, rust prevention, and rough machining.
