Abstract
A valve pin bushing assembly for an injection molding apparatus. The assembly includes a bushing body for connection to a manifold, a flexible barrier having a first end that is continuously connected to the bushing body, and a valve pin continuously connected to a second end of the flexible barrier. The valve pin extends through a nozzle in a downstream direction towards a mold gate, wherein the valve pin is movable in an upstream direction and in the downstream direction for opening and closing the mold gate. The flexible barrier seals a channel of molding material from an outside space.
