In mold manufacturing, we can usually hear casting and forging. What is the difference between these two manufacturing processes?
1. Casting: Casting is the process of smelting metal into a liquid that meets certain requirements, pouring it into a mold, cooling, solidifying, and cleaning to obtain castings (parts or blanks) with predetermined shapes, sizes and properties. It is the basic craft of modern machinery manufacturing industry.
The cost of the blank produced by casting is low, and it can show its economical efficiency for parts with complex shapes, especially with complicated inner cavities; at the same time, it has a wide range of adaptability and better comprehensive mechanical properties. However, the materials (such as metal, wood, fuel, molding materials, etc.) and equipment (such as metallurgical furnaces, sand mixers, molding machines, core making machines, shakeout machines, shot blasting machines, cast iron plates, etc.) required for casting Many, and will produce dust, harmful gases and noise and pollute the environment.
2. Forging:
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 is one of the two major components of forging. Through forging, the as-cast looseness and welding holes of the metal can be eliminated, and the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of machinery with high load and severe working conditions, forgings are mostly used in addition to simpler shapes that can be rolled, profiles or welded parts.
