ABSTRACT:
A purgeable plastic injection filter nozzle for trapping and eliminating contaminants from molten plastic material in a plastic injection molding apparatus. A nozzle body has an internal main channel therethrough for flow of the molten plastic. A purging hole intersects the main channel and exits the side of the nozzle body. A rotatable housing is mounted in the nozzle body at the intersection of the main channel and the purging hole. A trap is mounted in the rotatable housing for trapping contaminants in the plastic. The housing is rotatable between a first position wherein the trap is in the flow of the molten plastic, and a second position wherein the trap may be purged of contaminants through the purging hole.
