Parametric Study for Runner Modification of Die Casted Part with Venting Systems

High pressure die casting (HPDC) creates complex components by injecting the molten metal inside the cavity at high pressure. Failure in die casting may reduce product mechanical properties, surface quality, and life cycle. This research aimed to investigate the die-casting process of an inspection...
