ABSTRACT:
A heated manifold, for use in the distribution of heated plastic resins to the various cavities of injection molds for thermoplastic materials. The parts of the manifold interlock with each other and contain the high pressures generated by the injection molding presses. The components of the manifold are fitted with seals of metals dissimilar to the manifold, and with a higher coefficient of expansion than the manifold material. The system includes heated bushings which channel the plastic materials to the individual cavities and are fitted with a removable tip which can be adjusted to change the overall length of the bushing.
