The difference between casting, forging, stamping, and casting
The difference between Casting, forging, stamping, and casting
(1) Casting is the melting of the raw material to allow it to naturally form in the forming mold. Forging is to heat the raw material to a certain temperature and then use the tool to forge the forming. Stamping is to stamp the raw material with a suitable stamping die. Die Casting is to use pressure on the basis of casting The melted material is poured into the mold to give it a higher density or a more precise shape. Casting: The molten liquid metal fills the cavity to cool. Porosity is easily generated in the middle of the parts.
(2) Forging: It is mainly formed by extrusion at a high temperature. The grains in the part can be refined. The thickness of the part is basically equivalent to the stamping used for forming the sheet. The thickness of the parts is very different, the shape is complex, not hot, and die-casting is used. 1. Casting is divided into two types: high pressure casting and low pressure casting. To put it simply, after the metal is melted, the pressure is not the same as the pressure of the model, and the temperature of the heated metal is not the same as the machine used for casting. 2, forging is also a way of casting, the difference is that the temperature at the time of forging is lower, and some can be made of metal in semi-molten state.
(3) Stamping is a process in which a semi-finished product is made into a finished product with a punch press and the like at room temperature. 4, die casting is also a way of high temperature casting, when the structure is more complex, more difficult castings, you can use the die casting machine, the metal is heated to a liquid state, pressed into the mold, cooling the mold to open the product after removal Casting method.
