20090263525 | APPARATUS FOR MANUFACTURING LIQUID SILICON FOAM IN THE FORM OF ROLL - The present invention relates to an apparatus for manufacturing a roll-type liquid silicone rubber foam having no surface viscosity and a thin film shape with a greatly reduced thickness of 0.2 mm, which is capable of manufacturing a roll-type liquid silicone rubber foam having a predetermined width (300 mm-1,000 mm) in a continuous process useful for mass production. The apparatus includes a first PET film-supplying unit, adapted to supply a first PET film having a predetermined width; a liquid silicone rubber-supplying unit, adapted to apply a liquid silicone rubber containing a foaming agent and a curing agent on a surface of the PET film, which is supplied from the first PET film-supplying unit; a second PET film-supplying unit, adapted to supply a second PET film having no stickiness on the liquid silicone rubber applied to the first PET film, which is transferred from the first PET film-supplying unit through the liquid silicone rubber-supplying unit; a second PET film-recovering unit, adapted to recover the second PET film transferred from the second PET film-supplying unit; a foaming and curing unit, positioned between the second PET film-supplying unit and the second PET film-recovering unit and adapted to foam and cure the liquid silicone rubber disposed between the first PET film and the second PET film and to control a thickness of the liquid silicone rubber which is being foamed; and a liquid silicone rubber foam-take-up unit, adapted to take up the liquid silicone rubber foam as the final product into a roll form, which is transferred from the foaming and curing unit during the recovery of the second PET film into the second PET film-recovering unit. | 10-22-2009 |
20100028475 | COMPRESSION MOLDING METHOD AND DEVICE THEREFOR - A compression molding method capable of preventing contamination of abrasion powders generated by scoring to thereby improve the product yield is provided. The compression molding method, including a fixed mold and a movable mold arranged opposite each other, includes: contacting a slide board connected with a movable die plate on the movable mold side via a spring, with the parting face of the fixed mold by a spring force; further advancing the movable mold after injecting resin into a cavity in the mold, and compressing and molding the resin filled in the cavity by a core, provided in the movable mold, penetrating through the slide board. A resin film is disposed between the fixed mold and the slide board, and one surface of the resin in the cavity is compressed by the core via the resin film. | 02-04-2010 |
20100034911 | NANOIMPRINT STAMPER AND A FINE-STRUCTURE TRANSFER APPARATUS USING THE STAMPER - A nanoimprint stamper with a novel structure is provided that can simultaneously conform to two types of anomaly in the shape of a transfer substrate, i.e., a warpage and surface protrusions (including foreign objects) that differ greatly in the wavelength of variation, and which is capable of performing transfer with a smaller number of defects and in a uniform way. | 02-11-2010 |
20100119634 | CARBON COMPOSITE MOLD DESIGN - A mold assembly or system includes a moldbase that holds mold inserts and has embedded fluid lines to facilitate cooling during part formation. Mold inserts combine to form mold cavities that receive carbon fiber and resin components to form a carbon composite based part. A permanent release coating along a mold component surface that contacts the carbon fiber and resin components facilitates the release of the finished part from the mold component. Guide pins and guide pin receiving holes facilitate accurate alignment of mold components. Ejector pins within respective ejector pin shafts help eject a finished part from a respective mold component. An ejector pin shaft cover transfers force from an ejector pin to eject a finished part and also prevents substantial passage of resin into the ejector pin shaft. A fluid actuated ejection system provides fluid based mechanical forces to the ejector pins to facilitate finished part ejection. | 05-13-2010 |
20110274779 | DEVICE FOR PRODUCING A STRUCTURE - The invention relates to a method and a device for producing a structure made up of at least two bodies in a cavity of a mold defining the structure. | 11-10-2011 |
20130189387 | TEXTURED RELEASE LINER CONTAINING AN ORGANIC PARTICULATE PHASE - A release liner can include one or more release layers. The release layer can include a thermoplastic polymer matrix. Moreover, the release layer can include an organic particulate phase. The organic particulate phase can be dispersed in the thermoplastic polymer matrix. In one embodiment, the organic particulate can include micronized PTFE particles. The PTFE particles can be present in the release liner such that the surface roughness S | 07-25-2013 |
20140023740 | PRESS-FORMING MOLD AND METHOD FOR MANUFACTURING PROTECTIVE FILM FOR PRESS-FORMING MOLD - A press-forming mold has a protective film for preventing seizing during press-forming formed on at least a forming surface that comes into contact with a formed body. The protective film is formed by PVD. An arbitrary selection section extracted from the surface of the protective film is divided into a plurality of individual sections; and, when the gradient of the surface at the n | 01-23-2014 |
20150056316 | APPARATUS FOR MANUFACTURING EVA SHEET FOR SOLAR CELL SEALANT - The present invention relates to an apparatus for manufacturing an EVA sheet for a solar cell sealant by uniformly arranging and melting heat adhesive resins, comprising: a powder supplying unit provided in the form of a container containing a heat-adhesive resin powder inside same and comprising a discharge outlet in the lower portion thereof; a powder-arranging roll which has a concave recess pattern on the surface thereof so as to contain the heat-adhesive resin powder and which is arranged so as to seal the discharge outlet; a circulation belt which circulates while passing through a lower portion of the powder-arranging roll; a heater unit which heats and melts the heat-adhesive resin powder applied onto the circulation belt; and a peel-off roll disposed at the rear end of the heater unit so as to separate the heat-adhesive resin powder sheet melted into a film from the circulation belt . | 02-26-2015 |
20150064294 | Release Device Applied in Electronic Package - The present invention relates to a release device applied in electronic package, wherein the release device is attached to the inner surface of a transfer modeling mold for electronic package. In the present invention, the release device consists of a substrate and a release layer formed on the substrate, wherein the substrate is made of a plastic material with the thickness of 0.016 mm˜0.5 mm, and the plastic material can be PET, PP, PC, PE, PI, or PVC. Differing from the substrate, the release layer is made of a pure silica gel or a silica gel/rubber compound with the thickness of 0.02 mm˜2 mm. The release device can provide a releasing force for facilitating the modeled device formed by using the transfer modeling mold be easily separated from the mold, and avoid part of manufacture material from remaining in the inner surface of the mold. | 03-05-2015 |
