The final processing method of various properties are different casting is in the cavity made in advance into the molten metal liquid, to be solidified to form the required shape of the process; And forging is to heat red to a certain state (has not melted) block metal into the cavity, and give it a certain pressure to get the required product shape of the process upstairs of the forging method belongs to die forging.

Casting is divided into: pressure casting, investment manufacturing, metal casting, low pressure casting, ceramic casting, centrifugal casting, solid casting, magnetic casting, continuous casting, vacuum casting, extrusion casting, graphite casting. Forging is divided into: free forging, tire forging, die forging, precision forging, extrusion, upsetting forging, rolling forging.

The raw materials used in casting and forging are different. For brittle materials can not use forging, forging can only use plastic materials.

Casting raw materials are: gray cast iron, ductile cast iron, malleable iron, carbon steel, alloy steel, all kinds of bronze, aluminum alloy, stainless steel and so on.

Forging raw materials are: low and medium carbon steel, alloy steel, copper and copper alloy, aluminum alloy, magnesium alloy, titanium alloy, stainless steel and so on.
