Abstract
An injection molding system comprising:
- a manifold,a nozzle comprising a nozzle body having an outer circumferential surface that reduces in cross-sectional diameter or radial length beginning from a selected upstream point to a selected downstream point,a sleeve having a hollow bore having an inner surface complementary to the outer circumferential surface of the nozzle body such that the downstream end of the nozzle body is insertable into the upstream end of the hollow bore and further insertable downstream through the hollow bore to a point of maximum downstream travel at which the outside circumferential surface of the nozzle body engages the inside surface of the hollow bore, the engaged surfaces preventing further downstream travel of the sleeve body through the hollow bore.
