How Die Casting Works

December 25, 2025

The process relies on a "shot" of molten metal being injected at pressures typically between 1,500 and 25,000 psi.

The 5-Step Cycle:

Preparation: The die halves are cleaned and sprayed with a lubricant to regulate temperature and help the part release.
Injection: The die is clamped shut. Molten metal is injected into the cavity via a hydraulic piston.
Cooling: The metal solidifies rapidly inside the water-cooled die.
Ejection: The die opens, and ejector pins push the solid casting out.
Trimming: Excess metal (called "flash" or "runners") is clipped off using a trim die or saw
