Abstract: A shaped charge liner formed by injection molding, where the liner comprises a powdered metal mixture of a first and second metal. The mixture includes about 50% to about 99% by weight percent of the first metal, about 1% to about 50% by weight percent of a second metal, about 1% to about 50% by weight percent of a third metal. In one embodiment, the first metal comprises tungsten, the second metal may comprise nickel, and the third metal may comprise copper.

Abstract: A shaped charge liner formed by injection molding, where the liner components include powdered metal and organic binder. The liner components are blended then processed within an injection molding device and urged from the molding device into a mold where a liner shape is formed. The liner shape is debinded, both mechanically and chemically. Mechanical debinding involves heating and chemical debinding comprises treating the liner shape with a solution to dissolve and remove the binder components. The process of forming the shaped charge liner does not include sintering. The present process can also use “green products” formed by the injection molding device that are not debinded. A shaped charge case can also be formed using the present method. The added step of sintering can be applied to the process of forming the shaped charge case.

Abstract: A method of producing a liner for a shaped charge comprising mixing a composition of powdered metal with plasticizers and binders to form a paste. The paste is then particulated and injected into an injection mold. The paste is molded into a molded liner shape and then chemically treated to remove plasticizers and binders from the molded liner shape. After being removed from the injection mold the molded liner shape is sintered inside of a furnace. The powdered metal composition can be comprised of a mixture of from 60% to 97% by weight of powdered heavy metal and from 40% to 3% by weight of cobalt, or the powdered metal composition can be comprised of a mixture of from 60% to 97% by weight of powdered heavy metal and from 40% to 3% of copper, the preferred heavy metal being tungsten.
