Patent ID: 8741191

Claim:
A method of making an explosive charge liner comprising: introducing powdered material into a basin defined by a die block, wherein a punch is shaped to interact with the basin, wherein the punch and the basin define a conical shape; excluding the powdered material from a central portion of the basin; pressing the punch into the powdered material in the basin while the powdered material is excluded from the central portion of the basin; compressing the powdered material along the sides of the basin to form the explosive charge liner having an aperture in an apex area, wherein the powdered material achieves a design density along an entire length of the sides of the explosive charge liner based on excluding the powdered material from the central portion of the basin; and removing the explosive charge liner from the die block, wherein the explosive charge liner comprises the aperture in the apex area of the explosive charge liner corresponding to the central portion when removed from the die block.
