Hot runner system

A hot runner system comprising:

• a manifold having a heater for maintaining the manifold at a suitable processing temperature and a manifold channel network extending between a manifold inlet and a plurality of manifold outlets, the manifold channel network for distributing a molten plastic from the manifold inlet to the plurality of manifold outlets;
• a nozzle seated against the manifold and received in a respective manifold outlet, the nozzle having
• an extension portion received in the respective manifold outlet and in conductive thermal communication with the manifold,
• a body portion projecting downstream from the extension portion, and
• a nozzle channel extending through the extension portion and the body portion;
• and
• a nozzle support seated against the nozzle and in which the body portion of the nozzle is received, 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.
