Cast a variety of classification methods: according to its different metallic materials, divided into steel castings, iron castings, copper casting, cast aluminum, casting, casting of magnesium and zinc, titanium casting parts.

Each casting according to their chemical composition or further metallographic organization into distinct species.Such as cast iron can be divided into grey cast iron, nodular cast iron, vermicular cast iron, malleable cast iron, alloy cast iron, and so on;

By different cast molding method, can be divided into ordinary sand casting-casting, metal casting, die casting, centrifugal casting, continuous casting, investment casting, ceramic mold casting, electro-slag remelting casting double metal parts, castings, and so on.

With ordinary sand castings up to, about the total 80% of casting production.Non-ferrous metals such as aluminium, magnesium and zinc castings, mostly die castings.

Advantages of large machine tool castings:

1, good stiffness of resin sand, casting sand in the early high strength, which conditions the use of cast iron solidification process of graphitization expansion, effectively eliminate shrinkage, shrinkage porosity defects, achieving less gray cast iron, nodular cast iron, no riser casting riser.

2, full mold casting used in the production of polystyrene foam, and furans resin sand molding.

When the molten metal poured into the mold, and foam in high seashore under the action of liquid metal fast-gasification, combustion and energy dissipation, liquid metal replaced the original position occupied by the bubbles plastic Wang, solidification and cooling the same shape of full mold casting.

3, relatively speaking, LFC for production of single or small quantities of automobile covering parts, machine tool bed and other large traditional sand moulds, and so on has a big advantage, it not only eliminates the high costs of wood type, and easy to operate, shortens production cycles, increase production efficiency, with high accuracy of dimensions, stock allowance small, good surface quality

Flat panel manufacturing of large machine tool castings are mainly used in machine tools, simple accept the casting process.

Low pressure die casting is made of liquid metal under pressure through the cavity filling and solidification process b obtain a casting method of casting.

Due to the low pressure (20~60kPa), so called low pressure die casting.

The process is: in a sealed Crucible (or sealed tanks), into the dry compressed air, liquid metal under gas pressure, rising along the lift tube into the sprue 3, smooth runner 2 to enter the cavity within by 1, and keep the Crucible gas pressure on the liquid surface within, has been up to the complete solidification of castings.

And then discharge gas pressure on the liquid surface, is not in the lift tube solidification of liquid metal flow back to the Crucible, open and remove the castings.

Fundamental characteristics of the low pressure casting process: filling speed, pressure can be adjusted.

Used in low pressure casting molds, metal and Nonmetal-two categories.

Metal-non-ferrous metal castings for large numbers, and mass-produced, non-metallic molds used for single parts and small batch production, such as sand, graphite, ceramics and melting model can be used for low pressure casting, but in producing more is sand.

Low pressure casting with sand molding materials the permeability and strength should be higher than when gravity cast, cavity gases, entirely discharged exhaust duct and porosity of sand grains.

In order to fully take advantage of low pressure casting liquid metal under pressure from bottom to top feeding of castings, at the time of process design, consideration should be given to parts of solidification of casting away from the gate, gate finally solidified so during solidification of castings are feeding through the gate, realization of Directional solidification.
