Abstract:
1. A method of making an explosive charge liner having an improved density along the sides of the liner for use in an explosive charge, the method comprising: introducing powdered material into a basin defined by a die block, where a punch is shaped to interact with the basin, and wherein the powdered material comprises material denser than 10 grams per cubic centimeter; excluding the powdered material from a central portion of the basin; pressing the punch into the powdered material in the basin to form the explosive charge liner, wherein the explosive charge liner comprises an aperture in an apex area of the explosive charge liner corresponding to the central portion, and wherein the explosive charge liner achieves a design density along a length of the explosive charge liner based on the pressing, and fitting a plug into the aperture after the explosive charge liner is formed, wherein the combination of the plug fitted into the aperture and the explosive charge liner defines a shape, and wherein the plug contributes less than 10% of the length of an edge of the shape.
