| 20120088007 | MODULAR CLAMP STATION - A modular mold clamp assembly for use in a molding machine. The assembly has a frame with a base member and oppositely-facing end members, with the oppositely-facing end members having mounting areas provided thereon. First and second platens are movably mounted on the base member between an open and a closed position. The platens are mounted on the frame and are movable relative to the frame without transmitting forces to the frame. The frame, containing the platens, can be mounted or unmounted to the molding machine by the use of mounting hardware cooperating with the mounting area of the frame. | 04-12-2012 |
| 20120086156 | BLOW MOLDING APPARATUS - The invention is directed a rotary molding machine having a wheel mounted for rotation on a pair of shafts positioned along the rotational axis of the wheel. A first shaft cooperates with a first turntable of the wheel and a second shaft cooperates with a second turntable. The first and second turntables extend transversely to the rotational axis. A plurality of modular mold clamp assemblies are positioned on the wheel, with each modular mold clamp assembly being moveable between an open and a closed position. Each modular mold clamp assembly has mounting areas which are mounted with respective mounting locations each turntable. The modular mold clamp assemblies provide the structure and rigidity between the turntables to help maintain the turntables in position relative to each other. | 04-12-2012 |
| 20110052904 | PULTRUSION PROCESS AND RELATED ARTICLE - A pultrusion article and method for manufacturing the same is disclosed. The article has a core of cured thermoset material and foaming agent. Unidirectional fibers are distributed about the periphery of the article. A shell of cured thermoset material encapsulates the unidirectional fibers, with the shell having a greater density than the core. The core and the shell are bonded together. The article provides increased strength without the use of cross-fibers. | 03-03-2011 |
