The beneficial effect of considering mold deflection and mold spring-back on the prediction of packing pressure decay and part shrinkage of amorphous polymers has already been demonstrated. In this paper, a similar mold deflection effect is added to the recently developed flow-induced crystallization modelling of semi-crystalline materials during injection molding. The combined effect of improved gate freeze from the crystallization modelling and improved pressure decay due to the mold deflection effect results in improved part shrink and warp predictions. Simulation results are validated against molding data of cavity pressure, shrinkage and warp for a range of polymers.
