Patent abstract
A collar for an injection molding apparatus includes an upstream end for maintaining a head of a hot runner nozzle in contact with an outlet surface of a manifold and a downstream end for abutting a mold plate. An inner surface of the collar contacts an outer surface of the nozzle in order to align a nozzle channel of the nozzle with a manifold channel outlet of the manifold. A noncircular ridge protrudes from the inner surface of the collar in order to reduce contact between the outer surface of the nozzle and the collar.
