The meaning of the word is different:
1. Forging: Use hammering and other methods to make a metal material in a plastic state into a workpiece with a certain shape and size, and change its physical properties.
2. Casting: The processing method of melting the metal into a liquid and then pouring it into a mold, cooling and solidifying and cleaning to obtain a casting of the desired shape. Various objects with complex shapes can be made.
The production process is different:
1. Forging: is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes, and one of the two major components of forging (forging and stamping) .
2. Casting: It is a method of casting liquid metal into a casting cavity suitable for the shape of the part, and after it is cooled and solidified, the part or the blank is obtained.
Different uses:
1. Forging is generally used in the processing of forgings of a certain shape and size.
2. Casting is a relatively economical method of forming blanks, which is generally used for parts with complex shapes.
