HPDC Clamp Tonnage Calculator

Estimate the required clamping force for a high-pressure die casting machine.

Total shadow area of part + runners + overflows.

Typical: Al 30–50, Zn 20–35, Mg 30–45 MPa.

Suggested machine size

Tonnage = projected area × cavity pressure × safety factor. Use as a sizing estimate; always confirm against machine specs and gating/process conditions.
