264323000 | Sliding motion between material and mold surface (extruding finite articles) | 9 |
20080272518 | METHOD OF COMPRESSION MOLDING MOTOR VEHICLE COMPONENTS AND PARTS MADE THEREFROM - The invention is a method to make compression molded motor vehicle parts from a charge of composite material with resin and fibers, such as sheet molded compound. The parts have voids, such as holes and gaps, that form in the compression mold under heat and pressure and not in secondary processing steps. The resin in the charge is melts in a reservoir in the mold to form resinous material from the charge. A flow front of resinous material is allowed to flow into a flow path around a restriction corresponding to the shape of the void from the reservoir. The flow front carries sufficient reinforcing fibers into the flow path. At least part of a border for the void forms in the flow path. The configuration is allowed to at least partially set. | 11-06-2008 |
20090174118 | Method and device for nano-imprinting - A nanoimprint system according to one embodiment of the present invention is a system for performing a pattern transfer onto an object to be molded by pressing a mold against the object to be molded using a head, characterized in that the head has a flat pressing surface during pressing the mold and is slid onto the mold while pressing the mold. | 07-09-2009 |
20100133726 | Polymer mortar composite pipe material and manufacturing method - Composite material and plunger-cast pipe manufacturing method and system wherein the composite material includes waste, chemically unmodified PET material, one or more waste filler materials (e.g. rock crusher fines, lime sludge or waste coal combustion by-products), and fiber reinforcement (e.g. glass, metal, ceramic, carbon, organic, and polymer fibers) and wherein the PET material is melted and mixed in a container to disperse filler material and fiber reinforcement in the PET material. The resulting mixture can be formed into a tubular pipe shape using the plunger-cast manufacturing method and system wherein a plunger piston and inner collapsible mold are pushed into the melted composite material contained in an outer mold. When cooled and solidified in the mold, a composite material having a matrix comprising PET with filler material and fiber reinforcement distributed in the matrix is formed in the shape of a tubular body. | 06-03-2010 |
20100201034 | Method and apparatus for molding a laminated trim component without use of slip frame - An apparatus for producing a molded product from a sheet-form raw material blank has first and second mold tools that each respectively include a respective inner core mold and a respective outer edge mold laterally adjacent thereto. Drive elements drive the outer edge molds relative to a machine frame, and drive the inner core molds relative to the outer edge molds. A molding process involves closing the outer edge molds to hold an edge rim of the material blank while allowing slippage thereof, and then closing the inner core molds to three-dimensionally deform and mold a central portion of the material blank while pulling required additional material by slippage through the outer edge molds. A separate slip frame is not used. The edge rim held by the outer edge molds remains as a permanent mounting rim or flange of the finished molded product. Edge waste is minimized. | 08-12-2010 |
20100244321 | Production Of UHMWPE Sheet Materials - UHMWPE panels of large width may be ram extruded from a slit die in a stable process, by restraining a panel which exits the die below the crystalline melt temperature against movement away from the die by a back pressure device, so as to exert a back pressure between the back pressure device and the die, the back pressure device preferably constructed of a plurality of differentially adjustable elements so as to be able to compensate for changes in processing characteristics over time. Vertically restraining UHMWPE panels as they further cool also greatly improves product characteristics. | 09-30-2010 |
20100264564 | METHOD FOR SOCKET-FORMING AN END OF A THERMOPLASTIC MATERIAL TUBE, IN PARTICULAR OF A POLYOLEFINIC MATERIAL, TUBE FOR PRESSURIZED FLUIDS - A method for socket-forming an end of a thermoplastic material tube, according to which the end is firstly widened without forming the socket and is then stabilised; the widened and stabilised end being finally socket-formed. | 10-21-2010 |
20100314800 | SOLID STATE DEFORMATION PROCESSING OF CROSSLINKED HIGH MOLECULAR WEIGHT POLYMERIC MATERIALS - Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a combination of high tensile strength and high oxidative stability. The materials are especially suitable for use as bearing components in artificial hip and other implants. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted crosslinked UHMWPE. | 12-16-2010 |
20150008621 | METHOD OF PRODUCING PRESSED PAPER PIECE AND APPARATUS THEREFOR - The objective of the present invention is to provide a method of forming a pressed paper piece by deep drawing a sheet of blank that is primarily made of paper in use of a punch and a die, and a production apparatus for implementing the method, whereby no distinguishable wrinkles are formed in upright portions of the pressed paper piece. The method of producing a pressed paper piece according to the present invention, implemented when deep drawing a sheet-like blank that is primarily made of paper in use of a punch and a die, includes maintaining a predetermined gap between a first blank holder and the die in an outer peripheral region of a process portion of the blank and applying a pressure to a radially inner region thereof via a second blank holder, thereby reducing wrinkling by an effect of integrated functions exerted in both regions of the blank. | 01-08-2015 |
20150061187 | Method for producing a reinforcement member of composite material - A method for producing a reinforcement member of composite material. The method includes producing a planar preform by stacking sheets of pre-impregnated fibers, heating the preform, and deforming the preform on a mold surmounted by an upper die whose shape confirms to a central portion of the reinforcement member to be obtained. The reinforcement member wings are in contact with the mold at two opposite lateral sides of the upper die after deformation. The deformed preform is also baked. Prior to deformation of the preform, a coating is applied promoting a sliding between the preform and the mold during the deformation. The coating comprises two tear-off strips superimposed on each other. A first tear-off strip is in the form of a pre-impregnated material in contact with the preform and a second tear-off strip is in the form of a dry material superimposed on the first tear-off strip. | 03-05-2015 |
