Abstract
A hot runner nozzle tip and hot runner nozzle tip components are disclosed, the nozzle tip, and the assembled tip components, form a channel that has a first annular segment that has a cross-sectional area that increases in size away from a tip inlet, and a second annular segment that extends from the first annular channel segment. A hot runner tip assembly is also disclosed. The hot runner tip assembly includes a tip component having an attachment portion, an extension portion that projects from the attachment portion, and a bore that extends therethrough. A sleeve having a rib that extends outward therefrom surrounds the extension portion. The sleeve contacts the tip component at a first contact area and at a second contact area so as to create a void therebetween, and the first and second contact areas are offset from the rib.
