ABSTRACT:
An injection molding melt distribution manifold and method of making it with a melt passage extending from a single inlet to a plurality of outlets. The melt passage has a branching portion formed by machining matching grooves in opposing surfaces of two steel plates and then integrally brazing them together. The manifold has an embedded electrical heating element received in a channel formed by two other matching grooves in the opposing surfaces of the two plates. The channel is then integrally filled with nickel by heating under a partial vacuum. The electrical heating element which extends around and is in or near the same plane as the branching portion of the melt passage to ensure rheological and thermal balance of the melt flowing therethrough.
