抄録

This article deals with the polymer behavior within the mold cavity during the packing-holding process of injection-molding from the viewpoint of pressure transmission. The packing-holding process is used to be adopted in the practical injection-molding of polymeric materials to reduce the generation of molding failure due to shrinkage of polymer melt, but sometimes the packing-holding process may induce another type of failure such as residual strain and birefringence. The author revealed the behavior of polymer melt in the mold cavity by using visualization techniques, and the reduction mechanism of molding failure due to the packing-holding process was discussed on the basis of P-V-T characteristics of the polymer material.
