How much do you know about die casting?

Do you know how the name of die casting comes from? It originates from its reusable molds made from steel which are called dies. These molds can not be made from other alloys unless they can withstand high amount of pressure which is used to get the molten metal into the mold. Then you will know the reason why dies must be created from metal and not from sand or other material. The molds must be strong enough and not easy to crumble.

In certain industries where quantity and quality count, die casting process is considered to be a perfect procedure to manufacture high volume of same casting parts without any quality or pattern deviation in a very short time of period.

According to different alloys, there are different casting machines: the Hot-chamber and the Cold-chamber. If raw materials you use are zinc, tin and other lead-based alloys which all belong to low-melting point metals, then you can adopt hot-chamber die casting. The alloy

is to be melt and fed into a section of the machine which is called gooseneck. Then a piston forces the alloy into the mold.

For the casting alloy with higher melting points such as aluminium, zinc alloy with large composition of aluminium, magnesium and copper, the cold-chamber die casting is used. The alloy is to be melt in a separate furnace and then to be poured into the injection cylinder and at last to be shot into the mold.

Due to the high volume, relatively simple steps compared with other castings, good surface finish and dimensional consistency, die casting is commonly used to create commercial goods.
