Advantages of Die Casting-2

High production efficiency

High machine productivity.

Foe example, homemade J III 3 horizontal cold chamber die casting machine can finish 600-700 times per 8 hours. Small hot chamber die casting machine can finish 3000-7000 times per 8 hours.

Die toolings have long lifetime.

A die tooling that used for aluminum alloy parts have a lifetime of 60k-80k times. Mechanization and automation can be achieve easily.

Good economic effects

High usage rate of material

like metal injection molding parts, die casting parts with good accuracy and good roughness can be used directly, don’t need to be machined or few machined. Which improve the usage rate of material, and reduce the usage of manufacturing machines. The usage rate of material is around 60%-80%, the usage rate of drafts is around 90%.

Cheap prices

It can be achieved that match other parts made of other match with die casting parts by casting, which saves precious metal and work time, and satisfies function requirements, expand the application range, reduce assembling workload, and simply the processing.

However, die casting costs very much, which is the biggest weakness. Compared with other casting processings, its machines, die toolings and relative parts is very expensive. So die casting will get economic only when used for mass production. Besides, die casting is available only for metal with good flowability, and parts with weight between 30g with 10 kg. Normally, the last batch of finished parts have voids, and therefore can’t be heated or welded.
