Abstract

By means of this method it is possible to produce projectiles with single- or multi-element projectile bodies of different shapes and sizes simply and in a time-saving way. The jacket (1) of the projectile consists of a projectile tip (3), which is fixedly connected with a projectile casing (2) and has a centering device (5, 9) in its interior, in which the projectile body (6) is guided and maintained. The projectile body (6) is essentially cylindrical or has a diameter which increases toward the rear. The back of the projectile casing (2) is closed by means of a sealing body (15), which partially extends around the projectile body (6). In the course of producing the projectile, the projectile tip (3) is injection-molded to the projectile casing (2) in a first step, and in a second step the projectile body (6) is pushed into the centering device (5, 9). In a third step the sealing body (15) is injected into the projectile casing (2), after which the projectile body (6) is completely enclosed in the injected material at the front at a shoulder (11), laterally, and at the rear.

Claims

1. A projectile comprising:

a jacket;

a projectile body; and

,

a plastic injection molded rear sealing body;

wherein said jacket further comprises a plastic projectile tip which is injection molded onto a metal projectile casing so that said projectile tip extends forward from the front end of said casing and said projectile tip includes an interior recess to act as a centering device for said projectile body;

further wherein said projectile body comprises a plurality of partial projectile bodies which are inserted into axial alignment within said jacket with the assistance of said projectile tip recess and are fixed in place by injection molding said rear sealing body into a rear portion of said casing.

2. The projectile in accordance with claim 1 wherein the partial projectile bodies consist of different materials.

3. The projectile in accordance with claim 1, wherein at least one of the partial projectile bodies is selected from the group consisting of ductile metal, frangible metal and an incendiary composition.

4. The projectile in accordance with claim 1, wherein the partial projectile bodies have recesses and peg extensions for mutual centering.

5. The projectile in accordance with claim 1 wherein said projectile tip recess further includes longitudinal channels.

6. The projectile in accordance with claim 1 wherein the projectile tip and the rear sealing body are formed of a heat-resistant, fiber-reinforced thermoplastic material.
