What is high pressure die casting (HPDC)?

In a high pressure die casting process, molten metal or metal alloy is injected at high speed and high pressure into the mould. Horizontal high pressure die casting machines ensure the die closes completely. These are rated by how much closing force they can apply and, for Italpresse Gauss machines, that can range from 550 to 5700 tonnes.
