The difference between forging and casting

The difference between forging and casting lies in definition, technology and characteristics.

1, different definitions

Forging: by hammering, etc. Metal materials in plastic state are made into workpieces with certain shapes and sizes, and their physical properties are changed.

Casting: the process of melting metal into liquid and pouring it into a mold, cooling, solidifying and cleaning to obtain castings with required shapes, which can manufacture various objects with complex shapes.

2, the process is different

Forging: it is a processing method that uses forging machinery to exert pressure on metal blank to produce plastic deformation to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging (forging and stamping).

Casting: it is a method of casting liquid metal into a casting cavity suitable for the shape of the part, and cooling and solidification to obtain the part or blank.

3. Different characteristics

Casting: It can produce parts with complex shapes, especially blanks with complex cavities.

Forging: Forging can eliminate defects such as as as-cast porosity and optimize the microstructure of metal during smelting. At the same time, because the complete metal streamline is retained, the mechanical properties of forgings are generally better than those of castings of the same material.
