1) The casting has a certain degree of dimensional accuracy. Under normal circumstances, than ordinary forging, welding forming accurate dimensions.

2) the use of a wide range. Casting without casting size, thickness and shape of the complexity of the effects of casting thickness of up to 0.3 ~ 1000mm, length from a few millimeters to ten meters, the quality from a few grams to 300 tons. Most suitable for the production of complex shape, especially the cavity complex parts, such as a complex body, box, impeller, the engine cylinder, propeller.

3) low cost and overall economic performance, energy, material consumption and cost are other metal forming methods can not be compared.

4) The casting material can be used, almost to melt into a liquid alloy can be used for casting. Such as steel, cast iron fly all kinds of aluminum alloy, copper alloy, added alloy, iron alloy and alloy castings bowl. For the less brittle plastic alloy material (such as ordinary cast iron, etc.), casting forming process is the only feasible in industrial production to the most widely used cast iron, accounting for more than 70% of total production castings.
