Casting, forging, stamping, casting difference
(1) Casting is the melting of raw materials to make it in the molding mold natural Molding
Forging: Heating the raw material to a certain temperature and then using the tool Forge
Stamping: Stamping of raw materials with suitable stamping die
Die casting: On the basis of casting the pressure will be used to inject the melted material into the mold to obtain a higher density or more precise shape
Casting: Molten Liquid metal fills the cavity to cool. The hole in the middle of the workpiece is easy to produce.
(2) Forging: It is mainly formed by extruding method at high temperature. The grains in the workpiece can be refined.
The thickness of the parts is basically suitable for stamping with sheet metal forming.
Parts thickness, complex shape, not heated, with die-casting.
1, casting is divided into two kinds: high-pressure casting and low-pressure casting. Simply put, when the metal melts, pressure is different from the pressure of the model, the temperature of the heating metal and the machine used to make it.
2, forging is also a casting way, the difference is that the temperature of the forging is lower, some can be in the half molten state of the metal into the finished product.
3, stamping is at room temperature, with a punching machine and other products into the finished product process.
4, die-casting is also a way of high-temperature casting, when the structure is more complex, more difficult than the larger castings, you can use the die-casting machine, metal heating into liquid, pressure into the mold, cooling after the opening of the mold to remove the product of a casting.
