Simulation of Low Pressure Die Casting (LPDC) via STAR-Cast
Enhanced simulation of mold filling for LPDC-processes is based on STAR-Cast’s multiphase approach, which takes account of controlled gas inlet pressure curves. An easy- to- use, die-cycle warm-up menu enables accurate calculation of initial temperature distribution in the die. STAR-Cast also provides a full range of boundary definitions aimed at simulation of a range of different air outlet techniques.
