Abstract
A hot runner system includes a manifold having a heater and a manifold channel network extending between a manifold inlet and a plurality of manifold outlets for distributing a molten plastic. A nozzle seated against the manifold and received in a respective manifold outlet has an extension portion received in the respective manifold outlet, a body portion projecting downstream from the extension portion, and a nozzle channel extending through the extension portion and the body portion. The hot runner system further includes a nozzle support seated against the nozzle, the nozzle support including an upstream nozzle support and a downstream nozzle support, the downstream nozzle support is discrete from and in slidable contact with the upstream nozzle support, and the downstream nozzle support having a looser fit with the body portion of the nozzle than that of the upstream nozzle support's fit with the body portion of the nozzle.
