A tandem transfer press includes a fixed head (14), a moving platen (18) which is translatably disposed with respect to the head platen (14), and a floating die plate (20) which is translatably disposed between the moving platen (18) and the head platen (14). A first mold (42, 43, 44, 46, 48) having one or more cavities formed therein is disposed between the moving platen and the floating die plate. A second mold (52, 53, 54, 56, 58) having one or more cavities formed therein is disposed between the floating die plate and the head platen. A closing means (32) is attached to the moving platen (18) for closing the press by advancing the moving platen (18) toward the head platen (14) such that the first mold (42 ,43, 44, 46, 48) is sealingly engaged between the moving platen (18) and the floating die plate (20) and the second mold (52, 53, 54, 56, 58) is sealingly engaged between the floating die plate (20) and the head platen (14). A transfer means (50, 60) in flow communication with the cavities of the first and second molds transfers molding compound to the cavities of both the first mold (42, 43, 44, 46, 48) and the second mold (52, 53, 54, 56, 58) when the press is closed. |
