Die casting is metal type pressure casting on a die casting machine, which is the most productive casting process at present. There are two types of die casting machines, hot chamber die casting machines and cold chamber die casting machines. today we are talking about cold chamber die casting, Keep Reading.
What is cold chamber die casting
Cold chamber die casting is a kind of die casting machine in which the injection chamber and the injection punch are not immersed in the molten metal, but the quantitative molten metal is poured into the injection chamber, and then the plunger push the molten metal into the die casting die. after shaped and cool down. the casting parts been ejected out by ejector pin. this process is called cold chamber die casting, now Cold chamber die casting is mainly used for the production of aluminum alloys. Because the melting point of aluminum alloy is relatively higher.
What is the difference between cold chamber die casting and Hot chamber die casting?
The press chamber of a cold chamber die casting machine is separate from the holding furnace
The hot chamber die casting machine (hot air die casting machine) is immersed in the liquid metal of the holding and melting crucible, and the injection parts are not directly connected to the machine base, but are mounted on top of the crucible
Cold Chamber Die Casting Advantages and Disadvantages
|Cold Chamber Die Casting Advantages||Cold Chamber Die Casting Disadvantages|
|Thin-walled and complex products Can work||Wall thickness need thinner than 8mm|
|Large size parts can be produced||Easy have Shrinkage Porosity inside of Parts|
|Dimensional stability||Can not Run Heat treatment|
|Diversified surface treatment||Die casting die expensive|
|High efficiency||Take up more space, more manual operation|
|High strength, not too difficult technically and cheap|
|Wide range of applications|
