20110016946 | Coated Tooling - A coated forming tool including a tool component and a wear resistant coating on at least a portion of the tool component. The wear resistant coating includes a bottom coating layer and a top coating layer. The top coating layer has a thickness from about 1 μm to about 12 μm and the coating has a thickness ratio of the bottom coating layer thickness to the top coating layer thickness from about 0.5 to about 5. | 01-27-2011 |
20110111945 | INERT HIGH HARDNESS MATERIAL FOR TOOL LENS PRODUCTION IN IMAGING APPLICATIONS - A tungsten carbide material for use in precision glass molding applications having 6.06-6.13 wt. % carbon, 0.20-0.55 wt. % grain growth inhibitor, less than 0.25 wt. % binder, less than 0.6% wt. % impurities, and balance being tungsten. The tungsten carbide material has a nominal grain size of less than 0.5 microns. | 05-12-2011 |
20120003425 | TiAIN COATINGS FOR GLASS MOLDING DIES AND TOOLING - A system for precision glass molding comprising a substrate and a coating. The substrate has less than 1.2 wt. % minor constituents. The coating comprises TiAl | 01-05-2012 |
20130078328 | Coated Pelletizing Dies - Pelletizing ring extrusion dies comprising a die body having a plurality of holes, wherein each hole has surface at least partially coated with a low-friction coating. The low-friction coatings reduce surface temperatures during operation of the dies, which reduces volatilization and inconsistent flow of the material being extruded. The pelletizing ring extrusion dies possess improved tool life due to the low-friction coatings. | 03-28-2013 |
20130078331 | COATED PELLETIZING EXTRUSION DIES AND METHOD FOR MAKING THE SAME - A pelletizing extrusion die comprising a die body contains a plurality of extrusion holes. Each of the extrusion holes is defined by a defining surface of the die body wherein at least a portion of the defining surface has a low-friction coating deposited thereon. A method for applying the low-friction coating to the defining surface wherein the applying step occurs at a temperature equal to less than about | 03-28-2013 |
20130336776 | CLOSED IMPELLER WITH A COATED VANE - A closed impeller has a base cover, which has a base interior surface, and a second cover. A vane, which has an inlet distal end and an outlet distal end, is on the base interior surface. The vane has low and high pressure side surfaces wherein they have a low or high pressure midpoint, respectively. A hard coating is on the low and high pressure side surfaces. The hard coating has a minimum low and high pressure coating thickness at their respective midpoints. The minimum low, as well as high, pressure coating thickness ranging between about 0.085 and about 0.8 of either one of the maximum outlet coating thickness at the outlet distal end or the maximum inlet coating thickness at the inlet distal end, respectively. | 12-19-2013 |
20130337221 | COATED MEMBER FOR MOVEMENT RELATIVE TO A SURFACE AND METHOD FOR MAKING THE COATED MEMBER - A coated member, as well as a method for making the coated member, adapted for movement relative to a surface wherein a clearance distance between the coated member and the surface exists in a critical region of the coated member. The coated member has a finished size in the critical region. The substrate has an undersized substrate region of a minimum undersizing depth, which is equal to about seventy-five percent of the clearance distance. The undersized substrate region corresponds to the critical region of the coated member. A finished coating scheme is on the undersized substrate region wherein the finished coating scheme is the result of an oversized coating scheme being finished to form the finished coating scheme wherein the coated member is of the finished size in the critical region. | 12-19-2013 |
20140072469 | INERT HIGH HARDNESS MATERIAL FOR TOOL LENS PRODUCTION - In one aspect, tungsten carbide material systems are described herein which, in some embodiments, can provide desirable characteristics including chemical inertness, high hardness, reduced sensitivity to local compositional fluctuations and/or enhanced machining properties. In some embodiments, a tungsten carbide material described herein comprises 5.85-6.13 wt. % carbon, 0.85-1.05 wt. % chromium, less than 0.3 wt. % binder, less than 0.3 wt. % impurities and a balance being tungsten. | 03-13-2014 |
