Casting technology usually includes: ① casting mold ② melting and pouring of casting metal, mainly including cast iron, cast steel and casting non-ferrous alloy; (3) Casting processing and inspection. Casting treatment includes removing foreign bodies from the core and the surface of the casting, cutting off the riser, shoveling off burrs, overlapping seams and other protrusions, as well as heat treatment, shaping, rust prevention and rough machining.
Forging is a processing method that uses forging machinery to exert pressure on metal blank to produce plastic deformation, so as to obtain forgings with certain mechanical properties, shapes and sizes.
