Abstract: A resin transfer molding (RTM) apparatus (10) that includes: an extruder (4); at least two mold cavities (15) contained within a mold (16, 18) in the apparatus, arranged so that resin can be extruded from the extruder (4) into the mold; a nozzle (20) for delivering resin from the extruder (4) into the mold; runners (25) in the body of the mold to deliver resin from the nozzle (20) to a mold cavity (15) within the mold; a venting area (29) contiguous to each mold cavity to permit gases to escape from the mold cavity (15) when the mold cavity is infiltrated with resin; and a press (12) to force the mold (16, 18) closed during at least resin injection. An advantageous feature of the present invention is that the mold may be configured to accept a part (19) that is characterized by variations in length, width, and/or thickness, such as a wheel beam key. Also, an RTM process. The process includes: placing a porous preform, e.g.
