264073000 | RANDOM VARIEGATED COLORING DURING MOLDING | 14 |
20090026648 | VARIEGATED BUILDING PRODUCT FORMING PROCESS - A variegated building product solution includes a process for creating variegated building products through the introduction of color infused pellets with base pellets to create an aggregate, non-uniformly mixed pellet mixture as feed material for a molding process. In one aspect, the process involves the introduction of a set of color infused pellets into the stream of feed material pellets at preselected intervals. The feed material pellets includes color of a first hue, and the set of color infused pellets possess at least a second hue at variance from the first hue, such that the combined pellets form the aggregate, non-uniformly mixed pellet mixture. According to the process, the aggregate pellet mixture is moved into a molding chamber for molding of the aggregate pellet mixture into a variegated building product. | 01-29-2009 |
20090045540 | ARTIFICIAL MARBLE USING MULTICOLOR CHIP AND METHOD FOR PREPARING THE SAME - Disclosed herein are an artificial marble using multicolor chips, particularly striped chips, and a method for preparing the artificial marble. Since the artificial marble comprises multicolor chips in a new form together with conventional single-color chips, it enables achievement of various appearances, including designs and colors, thereby being highly differentiated from conventional artificial marbles containing combinations of single-color chips as well as displaying patterns and designs closely resembling natural granite. | 02-19-2009 |
20120241994 | SYNTHETIC CORK WITH A NATURAL CORK APPEARANCE AND METHOD OF MAKING IT - A method of producing random and irregular markings and impressions on synthetic cork stoppers so as to closely mimic the surface texture of natural cork, and the stoppers produced thereby.-In one embodiment, the stopper is produced in a mold featuring a textured inner surface. In another embodiment, the stopper is extruded. | 09-27-2012 |
20120313281 | Ornamentation Of Composites - A method for decorating a composite placed in a mold in a resin transfer molding process includes selectively depositing unbonded pigments on one or more areas of a preform of the composite, and injecting a resin into the mold via one or more resin input ports operably connected to the mold. The injected resin carries the selectively deposited unbonded pigments on a path on one or more areas of the preform of the composite along a direction of flow of the injected resin, thereby creating ornamental pigment flow patterns in the composite for decorating the composite. The method also creates bands of ornamental pigment flow patterns by depositing the unbonded pigments on a transfer medium positioned on the composite, positioning the transfer medium in proximity to the resin input ports, and selectively injecting the resin onto the transfer medium deposited with the unbonded pigments, via the resin input ports. | 12-13-2012 |
20130069267 | Method And Apparatus For Forming Color Swirls In Plastic Containers - Single or multiple colorants are infused into a thermoplastic material during melt processing to form preforms and plastic containers exhibiting a marbleized or swirl-type pattern. A base resin and colorant may be fed into an extruder having an extrusion screw and/or barrel modified in a manner to cause incomplete and non-uniform mixing. The modifications may include notches in some of the flights along the extrusion screw, a reduction in the depth or omission of some of the flights, a reduction in diameter of the extrusion screw, or the provision of a marbleizing torpedo near the discharge nozzle. Other techniques include introducing the colorant into vents present along the barrel, using a barrier screw to keep the components separate along the length of the barrel, using a high pressure pump for introducing the colorant near the discharge nozzle, or using multi-material co-injection techniques for co-injecting the base resin and colorant. | 03-21-2013 |

264074000 | Of surface portion only | 2 |
20090039538 | METHOD OF FORMING A THERMOPLASTIC ARTICLE - A method of forming a thermoplastic article, including the steps of (a) forming a workpiece of a thermoplastic material of a first colour by injection molding; (b) applying a second colour on the workpiece by over-molding part of the workpiece with the thermoplastic material of the second colour by injection molding; (c) raising the temperature of the workpiece to at least the forming temperature of the thermoplastic material; and (d) enlarging the workpiece by blow molding. | 02-12-2009 |
20120181719 | APPARATUS AND MOLD ASSEMBLY FOR MOLDING AND DEMOLDING CEMENTITIOUS PRODUCTS AND METHODS THEREFOR - An assembly for molding and demolding hardened cementitious products comprises a flexible mold and a demolding apparatus. The flexible mold has a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter. The apparatus for demolding the hardened cementitious products from the flexible mold comprises a conveyor, a holding member, a clamp, and a movable member. The conveyor conveys the flexible mold. The clamp grips a portion of the perimeter. The holding member engages the mold. The ovable member moves the clamp and the clamped portion of the mold about the holding member thereby disengaging the flexible mold from the cementitious material. | 07-19-2012 |

20090206503 | In-Line Process for Preparing Wood Plastic Composite Panel With the Appearance and Texture Similar to Natural Lumbers and Apparatus Therefor - Disclosed herein are a method of manufacturing a wood plastic composite panel, including a panel manufacturing process of extruding and cooling a resin complex, such that wood fiber is uniformly dispersed into a synthetic resin matrix, to manufacture the resin complex into the form of a panel, an embossing process of forming a wood pattern corresponding to the cut-open surface of a natural lumber on the surface of the panel to a predetermined depth, and a brushing process of removing some of a synthetic resin layer from the surface of the panel to form linear micro concavo-convex parts to a predetermined depth, and an apparatus for manufacturing a wood plastic composite panel that is capable of efficiently performing the same. The method of manufacturing a wood plastic composite panel according to the present invention has the effect of directly realizing a wood pattern, which has the appearance and the texture similar to the open-cut surface of a natural lumber, on the surface of the wood plastic composite panel, and, at the same time, maximizing the advantage of the material comprising the wood fiber and the synthetic resin. | 08-20-2009 |
