What is the difference between casting process and forging process?

There are so many castings and forgings on the market nowadays that many people don't know much about these two processes. What is the difference between casting and forging? In what areas are they used?

Casting and forging are actually quite differentiated. I believe you are already very familiar with castings, casting refers to the hot metal is artificially and naturally solidified and molded to obtain the demand for castings, in the process of production, there will be pores, sand holes and other defects. Nowadays, steel castings have been widely used in many industries, such as construction machinery, construction machinery, aerospace equipment, etc. Forging refers to the use of forging mechanical tools to exert a certain pressure on metal materials, so as to carry out plastic deformation and other processes to obtain forgings with a certain shape and function. In the process of forging, the porosity defects of the forging will be eliminated, which greatly improves the strength of the forging. Forgings are often used in diesel engines, marine forgings, and aircraft forgings.
