ABSTRACT:
A modular manifold system is described. A plurality of generally cylindrical manifold components engage a melt distribution element. The manifold components each have a generally cylindrical body which has an annular cavity formed therein which axially extends with the component body for a predetermined length which separates the component body from a component inner core. A melt runner passage extends axially through the inner core. A heating element in the form of a ceramic insulator sleeve occupies a portion of the annular cavity with a particulate refractory material occupying the remainder of the annular cavity.
