Selection of Tool Steel for High Pressure Die Casting Dies High-pressure die casting (HPDC) is a high-speed process in which molten metal is injected into a steel die under pressures of 6.9\u2013206.8 MPa (1,000\u201330,000 psi). The cavity fills and solidifies within seconds, exposing the die surface to repeated thermal and mechanical loading.
