DIRECT VISUALIZATION OF CONVENTIONAL INJECTION MOLDING

摘要

A transparent mould with two injection locations, allowing flow visualization on both conventional and two materials injection molding, was used in this research. The aim of this work is to monitor and assess the polymer melt behavior under controlled processing conditions, during the filling and holding stages of the molding cycle. Visual access in the mould is allowed by the sapphire windows, surrounding the cavity. Visualization results are combined with local pressure and temperature measurements and compared with Moldflow MPI software simulations.
