High Pressure Die Casting - an overview ScienceDirect

3 High-pressure Die Casting. High-pressure die casting is a process in which molten metal is forced under pressure into a securely locked metal die cavity, where it is held by a powerful press until the metal solidifies. After solidification of the metal, the die is unlocked, opened, and the casting ejected.

HPDC vs LPDC Die Casting cameldie

High-pressure die casting (HPDC) High-pressure casting is a process in which molten metal is poured into a pressure chamber so that the molten metal fills the mold cavity at high speed and then solidifies under high pressure to form a casting. The flow speed during filling can reach 30-80mm/s, and the time for filling the cavity is extremely short.
