Abstract
A method of making an explosive charge liner comprises introducing powdered material into a basin defined by a die block, where a punch is shaped to interact with the basin, 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, and removing the explosive charge liner from the die block. The explosive charge liner comprises an aperture in an apex area of the explosive charge liner corresponding to the central portion when removed from the die block.
