摘要： A method of making a fragmenting structure for an explosive device includes placing a volume of fragments of a deformable metal material into a press mold, the fragments having sufficient surface adhesiveness to adhere to each other upon being compressed together, e.g., by coating the fragments with adhesive. The fragments are compressed together in the press mold to form the fragmenting structure as a rigid and substantially void-free structure of compression-deformed, mutually adhering metal fragments, the fragmenting structure being sized and shaped for subsequent incorporation into the explosive device. An explosive device includes an explosive charge and a fragmenting structure adjacent to the explosive charge, the fragmenting structure being a rigid and substantially void-free structure of compression-deformed, mutually adhering metal fragments. The structure may have been manufactured by the disclosed method.

摘要： Disclosed is a cartridge case for various caliber ammunition that consists essentially of a powdered metal and/or powdered metal alloy that is formed into the cartridge case through an injection mold processing. Also disclosed is a method for forming a cartridge case, which may include use of Metal Injection Molding (“MIM”) processes to produce the cartridge case which retains a primer, propellant, and/or a bullet. The method can include metal injection molding an initial part, and also at least one of tapering and trimming the initial part to form the finished cartridge case. Further embodiments can include the use of Finite Element Method (FEM) analysis to develop an optimized MIM design.

摘要： The firearm cartridge has an upper chamber adapted to house gunpowder and a bullet, a lower pocket adapted to house a primer, and a flash hole extending there between. The lower pocket has a ledge disposed generally perpendicularly to the flash hole. The flash hole is formed with a perimeter wall that has a convex curvature adjacent to the ledge of the primer pocket. The convex curvature of the flash hole perimeter wall can either be a continuous curve, or can be approximated by a series of smaller facets, as might be produced in various manufacturing processes.

摘要： The invention relates to a method for producing a deformation bullet, consisting of a projectile core made from lead in a tombac jacket. So that the performance of the bullet, such as the accuracy, deformation and energy transfer in the target medium can be adjusted and a homogeneous core of the bullet is created, the structure of which has a predefined breaking point on the center axis of the bullet, the following method steps are suggested: a. manufacture of a cup-shaped tombac jacket, introduction of lead into the tombac jacket and soldering of the lead with the tombac jacket in order to produce a blank, b. introduction of a pre-existing defect into the lead of the blank by pressing a die displaceable on the center axis of the blank into the lead and then removing the die, c. final pressing of the blank into the final shape of the deformation bullet with outer longitudinal grooves on the ogive and with a rear inner cone 6, wherein a pressing force larger than 7000 N is used during the final pressing process.
