Abstract
A flexible plate system for a hot runner assembly includes a backing plate; a manifold plate detachably connected to the backing plate; a manifold positioned between the backing plate and the manifold plate and having at least one nozzle associated therewith; and wherein the manifold plate has at least one plate slot that allows the nozzle to extend through the manifold plate and having at least a first lateral dimension substantially larger than the outside diameter of the nozzle. The manifold plate and the backing plate may be configured to have at least one manifold plate cavity and at least one backing plate cavity to accept at least one nozzle insert and at least one piston cylinder insert respectively, the nozzle insert having a nozzle bore or a plurality of insert slots therethrough for installation of the nozzle, and the piston cylinder insert having a cylinder bore for a piston cylinder.
