Patent application number | Description | Published |
20080315449 | METHOD AND APPARATUS FOR FORMING HIGH STRENGTH PRODUCTS - A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a cumulated laminated output with nano-sized features. | 12-25-2008 |
20120189789 | METHOD AND APPARATUS FOR FORMING HIGH STRENGTH PRODUCTS - A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape. | 07-26-2012 |
20140034355 | MICROLAYER COEXTRUSION OF ELECTRICAL END PRODUCTS - The present invention including the disclosed embodiments thereof generally relate to extruding multiple laminated flow streams using microlayer extrusion, and in particular to creating and forming products with electrical properties that are formed from layers and particles with dimensions in the micro to nanometer range. | 02-06-2014 |
20140242310 | Extrudable Oriented Polymer Composites - A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of micro- to nano-polymer layers. These new shapes contain contiguous layers of milli- to nano-polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries. | 08-28-2014 |
20140308506 | Extrudable Polymer Composites With Membrane Barrier Properties - The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to the cyclical extrusion of materials to generate small sized grain features, generally in the range of nanosized grain features, in a tubular or profile shape, in which the individual nanolayers possess pores and/or polymer crystals oriented parallel to the extrusion flow direction and including products with enhanced permeation properties. | 10-16-2014 |
20150147496 | EXTRUSION WRAPPING DEFLECTOR - A method for wrapping a stream of material or stream of layers of materials includes feeding a stream of material or stream of layers of materials into a die containing a wrapping deflector which acts to wrap the stream into a tubular or profile shape. | 05-28-2015 |
20150158233 | Method Of Tubular Microlayer And Multi-Component Co-Extrusion Via Deflector Perturbation - The present invention relates to a method of transforming multilayered and/or multi-component streams into tubular shapes prior to or during extrusion by passing the streams over a deflector. The invention also relates to dies containing spiral, bowtie, circumferential and/or wrapping deflectors and products made by such methods. | 06-11-2015 |
20150298380 | MULTICOMPONENT APPROACH TO STANDARD AND MICROLAYER COEXTRUSION - The aspects of the disclosed embodiments provide unique extrusion methods and apparatus to create a multi-component product made from various streams of molten plastic. The method for creating multicomponent multilayered products includes merging multiple streams containing individualized component and layer designs into a single stream to form a rod, tube, pipe, filament, or profile shape. | 10-22-2015 |
20150298381 | METHOD OF MULTI- DEFLECTOR BALANCING AND STRENGTHENING - The disclosed embodiments relate to extrusion systems and involves a method to promote self-balancing of flow velocity while enhancing the strength of the end product by off-setting seams. This invention focuses on using a system of more than one deflector to produce multiple rings which are then quickly merged to produce a more quickly balanced ring. | 10-22-2015 |
