Abstract
A method of manufacturing a casing for an ammunition cartridge includes injection molding a first polymer forming a first part of the casing. The first part is cylindrically shaped along a longitudinal axis extending from a projectile end opposite a stepped end. The stepped end forms a first end of a mechanical connection. A portion of the injection mold is removed and an additional injection mold is disposed about the stepped end of the first end of the first part and a second polymer injected forms a second part of the casing. The second part includes a second stepped end forming a second end of the mechanical connection. The first and second end are mechanically locked together preventing a separation of the first part from the second part. A thermal swagging tool forms a conical tapered region along the projectile end of the first part.
