ABSTRACT:
A seal is provided between a nozzle and a manifold. The seal provides a melt channel between an outlet of the manifold and a nozzle channel. The seal has higher thermal expansion coefficient than both the nozzle and the manifold to provide an improved seal between the manifold and the nozzle when the injection molding apparatus is at an operating temperature.
