Verwendet man für die Herstellung von Kartuschenrohren eine HD-Polyethylen-Formmasse, welche ein Gleitmittel enthält, kann auch bei hohen Produktionsgeschwindigkeiten störungsfrei gearbeitet werden.
摘要:
A high strength polymer-based cartridge casing (100) can include a first end having a mouth (208) and a neck (206) extending away from the mouth. Next, a shoulder (204) extends below the neck and away from the first end. The cartridge can be have a frangible portion capable of being split upon discharge of a projectile. The shoulder (204) can have unequal outside and inside shoulder angles. The casing can also include an insert (400) having a rim at one end or a plurality of ribs extending longitudinally along a wall between the shoulder and the bottom of the cartridge and spaced radially from each other around a circumference of the wall. A projectile (50) can be disposed in the mouth and a relief can be disposed on the neck near the mouth and projectile. The relief can form a gap between the neck and the projectile to receive an adhesive.

摘要:
An insert for a high strength polymer-based cartridge casing (400) can include an outside, an inside formed within the insert, and a back end (402) disposed at a rear of the cartridge casing. The back end includes a rim (406) and groove (404) disposed around the outside of the insert and a primer pocket disposed inside the back end. Also included is a front end, opposite the back end, having an overmolded area (408) disposed around the outside of the insert above the primer pocket and a basin, having a depth, formed inside the overmolded area. A flash hole (418) can be included inside the insert and communicating between the primer pocket (416) and the basin. The flash hole has a perimeter and a ring disposed around the perimeter of the flash hole, including a height starting at a bottom of the basin, disposed toward the front end, and less than the depth of the basin.
