Casting is defined: the casting method has a certain shape,
microstructure and mechanical properties of metal parts.
Castings, cast in a variety of methods for metal forming
objects, namely the smelting good liquid metal, with casting,
injection, inhaled, or other casting methods into the prepared
mold, after cooling the shakeout and cleaning, and
post-treatment of a certain shape, size and properties of
objects.
Casting has a variety of classification method: according to the
different metal materials used, divided into steel casting, iron
casting, copper casting, aluminum casting, magnesium castings,
titanium zinc castings, castings, etc. And each type of castings
can be according to their chemical composition or the
microstructure is further divided into different kinds. Such as
iron castings can be divided into grey iron castings, ductile
castings, malleable pieces, vermicular casting, alloy casting,
etc.
According to cast molding method is different, can be divided
into ordinary sand mold casting, the casting metal mold casting,
die casting, centrifugal casting, continuous casting parts,
investment casting, ceramic type casting, electroslag casting
pieces, double metal castings and so on. With ordinary sand
mould castings used most, accounts for about 80% of the total
casting production. And non-ferrous metals such as aluminum,
magnesium, zinc castings, is die casting. My factory produces
various ductile castings, castings, wear-resistant castings,
pump body, pump casing, impeller skeleton.
