ABSTRACT:
A plastic injection blow molding manifold has progressively smaller passageways defined at the mating surfaces between its two primary members. The circular cross sectional inlet area is reduced by one-half in a first cross passageway, and then further reduced in two additional cross passageways in an eight nozzle version. All of these cross passageways are defined at said mating surfaces, and the respective ends of such additional cross passageways communicate with paired outlets, each of which outlets has an associated nozzle and coaxially arranged heating element.
