ABSTRACT:
A two-piece hot runner manifold with plastic flow channels formed as recesses in the two mating surfaces. One or more mating structures, such as posts and sockets, ridge and groove configurations, or the like, are provided along the mating surfaces of the two mating manifold members. A bonding material, such as bronze, can be used to hold the two pieces of the hot runner manifold together. Cross pin members are preferred for use in securing the two mating manifold members together.
