  • Publication number: 20160151952
    Abstract: 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 520° C.

  • Publication number: 20130078328
    Abstract: 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.

  • Publication number: 20100104861
    Abstract: Metalforming tools comprising WC—Co cemented tungsten carbide are provided for warm and/or hot working operations. The WC—Co materials have controlled compositions and microstructures, resulting in properties that allow the material to be used in such warm and hot metalworking applications.

  • Patent number: 6551375
    Abstract: Tungsten powder is mixed with a second powder metal and a binder to be used as small arms projectiles and shot pellets for use in shot guns which is cost effective to produce and which can perform ballistically. Ballistic performance equal to or superior to that of lead would be offered by a material having a specific gravity equal to or greater than lead. The non-toxic projectiles are manufactured in a cost-effective process; yet still produces projectiles and shot pellets that can perform ballistically. This projectile composition can perform substantially as well as lead and lead alloys or better without the need to fabricate the composition from a high temperature molten state which requires large amounts of energy input. In one particular embodiment of the invention, the tungsten powder is blended with iron powder and Portland Cement for constructing projectiles. The tungsten, iron and Portland Cement (W/Fe Portland cement) shot provides a satisfactory substitute for lead shot.
