1. Casting is a process which metal liquid is poured into a casting mold.
After cooling, solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. Casting blanks are almost shaped, so that they can be processed without machining or a small amount of processing, reducing costs and machining time.
They are mostly used to produce complex shapes and normal working condition.
2. Forging is a processing method that uses forging machinery to exert pressure to metal blanks obtaining mechanical properties, certain shapes and sizes. After the steel is forged, its internal structure has great changes.
A. The coarse grains are crushed into small and uniform grains and compacted tightly with each other.
B. The coarse grains are crushed into small and uniform grains and compacted tightly with each other.
C. Some brittle impurities are pulverized, while plastic impurities are elongated with the deformation of the metal and become fibrous structure, which greatly enhances the toughness of the material
