Abstract
An injection molding nozzle tip insulator includes an inner annular portion in contact with the injection molding nozzle tip, and an outer annular portion in contact with the inner annular portion, the outer annular portion being less thermally conductive than the inner annular portion so that the insulator has a stepped heat gradient profile from an inside to an outside thereof.
