Abstract
A hot runner system having a nozzle received in a well in a mold plate. The nozzle has a melt channel, a nozzle body through which the melt channel extends, and a collar connected to and spaced apart from the nozzle body. A manifold is seated against the nozzle. The manifold has a melt channel in fluid communication between a source of moldable material and the nozzle channel. A bearing member against which a seating surface of the collar is supported is received in the well, and a biasing member is seated between a step in the well and the bearing member. The biasing member has plate loading surface and a nozzle loading surface. The nozzle loading surface and the plate loading surface are concentric with the seating surface of the collar and are circumferentially offset from the seating surface of the collar in opposite directions.
