ABSTRACT:
A stack injection molding apparatus includes a melt homogenizing element provided between a first transfer nozzle, which is coupled to a melt source, and a second transfer nozzle, which is coupled to a manifold. The melt homogenizing element is used for redistributing a melt stream in order to provide a homogenized melt stream having a generally uniform temperature and viscosity profile or sectional distribution.
