铸造分为两种：高压铸造和低压铸造．简单的说，就将金属融化后，压如模型的压力不一样，加热金属的温度和用来铸造的机器都不一样．
There are two kinds of casting: high-pressure casting and low-pressure casting. In short, after melting the metal, the pressure is different, and the temperature of heating the metal is different from the machine used for casting
2、锻造也是一种铸造的方式，区别在于锻造时的温度更低一些，有些可以在半熔化状态下将金属做成成品的方式．
2. Forging is also a way of casting. The difference is that the temperature of forging is lower. Some methods can make metal into finished products in semi molten state
3、冲压就是在常温下，用冲床等机器将半成品做成成品的过程．
3. The process of making semi-finished products by punching machine at room temperature
4、压铸也是高温铸造的一种方式，当遇到结构比较复杂，难度比较大的铸件时，可以使用压铸机，将金属加热成液态，压入模具内，冷却后打开模具取出产品的一种铸造方式。
4. Die casting is also a way of high-temperature casting. When encountering castings with complex structure and great difficulty, a die casting machine can be used to heat the metal into liquid state, press it into the mold, open the mold after cooling, and take out the product.
