ADHESIVE LIP FOR A HIGH STRENGTH POLYMER-BASED CARTRIDGE CASING AND MANUFACTURING METHOD

摘要

A high strength polymer-based cartridge casing can include a first end having a mouth and a neck extending away from the mouth. Next, a shoulder extends below the neck and away from the first end. The cartridge can have a frangible portion capable of being split upon discharge of a projectile. A projectile 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.

主权项

1. A high strength polymer-based cartridge casing inclosing a volume, comprising:
a first end having a mouth; a neck extending away from the mouth; a shoulder extending below the neck and away from the first end; a bullet configured to impact a target and disposed in the mouth; and a relief formed in the neck proximate to the mouth and forms a gap between the neck and the bullet; and an adhesive disposed in the gap and in contact with the bullet, wherein at least the mouth, the neck, the shoulder and the relief are formed of at least one polymer.
