Forging casting 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. Forging (forging and stamping) is one of the two major components. Through forging, it can eliminate the defects such as loose as-cast produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than castings of the same material......
