ABSTRACT:
A heated resin supply hose for supplying molten resin in a molding process, such as a RTM process, includes a removable inner core tube or conduit that can be readily removed from reusable supply hose components after each injection cycle to make a molded article. The reusable hose components include a core-receiving conduit for slidably receiving the core conduit and a heating element on the core-receiving conduit as well as additional hose component layers. The used core conduit having residual resin therein is removed from the core-receiving conduit and replaced by a new core conduit that is inserted in the core-receiving conduit in making another molded article.
