ABSTRACT:
An injection molding manufacturing apparatus and method that facilitates the formation of a blind hole in a two-component assembly in which a first component is molded in-situ in a second component. A first cylindrically-shaped component having a transverse socket with a blind hole is injected molding and then transferred into and molded in-situ within the second component in such a way that the blind hole is blocked-off by a second central core pin during molding of the second component. In this manner, the two-component in-situ assembly includes a blind hole formed in a socket.
