The die casting process consists of several key steps. First, the die is pre-heated to ensure consistent metal flow and reduce thermal shocks. Next, the molten metal is injected into the die under high pressure, filling the cavity quickly and preventing the formation of air pockets. Once the metal cools and solidifies, the die is opened, and the finished part is ejected. This method offers high efficiency and accuracy, making it ideal for piston production.
