ABSTRACT:
A process for integrally molding an assembly having parts in a die lock situation, in a single modeling step, with the process steps of has the steps of providing a composite component with a predefined contour, molding a core fuel rail integrated with the composite component, connecting the core fuel rail to a main core structure, overmolding the combined core fuel rail and main core structure to form a finished assembly, removing and melting out the combined core fuel rail and main core structure and extracting the composite component to provide the finished assembly with a substantially accurate finish. The core fuel rails and injector pockets are molded together with the main manifold body in a single step although the injector pockets are in a die lock situation relative to the main manifold body. The interior surfaces of the injector pockets molded using the present invention have a substantially accurate finish.
