The injection system is responsible for injecting the molten metal into the mold cavity. This system consists of a plunger, which forces the metal into the mold, and a nozzle, which controls the flow of metal. The injection system operates at high pressure, typically around 100-200 MPa, to ensure that the metal is injected into the mold with precision and accuracy.

The mold cooling system is another critical component of the cold chamber die casting machine. Once the metal has been injected into the mold, it must be cooled rapidly to ensure that it solidifies correctly. The mold cooling system typically uses water or oil to cool the mold, and the cooling time varies depending on the size and complexity of the part being cast.
