ABSTRACT:
An injection molding system having a manifold nozzle connection that accommodates thermal expansion of the system. A manifold nozzle tubular connector is receivable at a first end within a manifold and at a second end within a nozzle and has a length that bridges a space between opposing surfaces of the manifold and nozzle. The first end of the tubular connector may be threadably and/or permanently attached within a manifold bore in a downstream surface of the manifold with the second end of the tubular connector being slidably received within a nozzle bore in an upstream surface of the nozzle or within a nozzle melt channel. Alternatively, the first end of the tubular connector may be slidably received within a manifold bore in the downstream surface of the manifold or within a manifold melt channel with the second end of the tubular connector being threadably and/or permanently attached within a nozzle bore in an upstream surface of the nozzle.
