ABSTRACT:
Multi-cavity injection molding apparatus having several melt distribution manifolds interconnected by elongated connector bushings. Each connector bushing has an outer sleeve which fits over a nonthreaded cylindrical portion of the main body. The main body is made of a material such as steel with sufficient strength that thermal expansion pushes the manifolds into operating positions slightly further apart without damaging the connector bushings. The outer sleeve of each connector bushing is made of a material such as copper having a coefficient of expansion sufficiently greater than the main body whereby thermal expansion results in the connector bushing forming a seal against melt leakage.
