Projectile, Ammunition and Method of Manufacturing a Projectile

Abstract

The present invention relates to a projectile, in particular a diabolo, for ammunition of a pneumatic weapon, a CO2 weapon or a spring-loaded weapon, wherein the projectile is made of a mixture comprising metal and 2 to 15% by weight of plastic, based on the total weight of the projectile.

1 . A projectile, for ammunition of a pneumatic weapon, a CO2 weapon or a spring-loaded weapon, wherein the projectile is made of a mixture comprising metal and 2 to 15% by weight of plastic, based on the total weight of the projectile. 
     
     
         2 . The projectile according to  claim 1 , wherein the metal is contained in the projectile in an amount of 85 to 98% by weight, based on the total weight of the projectile. 
     
     
         3 . The projectile of  claim 1 , wherein the metal is selected from the group consisting of copper, iron, zinc, tin, magnesium, tungsten, cemented carbide, sintered metal, and mixtures thereof. 
     
     
         4 . The projectile according to  claim 1 , wherein the metal in the projectile is in the form of particles. 
     
     
         5 . The projectile according to  claim 4 , wherein the particles have an average diameter of 5 to 15 μm. 
     
     
         6 . The projectile according to  claim 1 , wherein the plastic is a thermoplastic elastomer. 
     
     
         7 . The projectile according to  claim 6 , wherein the thermoplastic elastomer is natural rubber or an ethylene alkyl acrylate copolymer, preferably ethylene butyl acrylate copolymer. 
     
     
         8 . The projectile according to  claim 1 , wherein the mixture has a density of 4 to 12 g/cm3. 
     
     
         9 . A projectile for ammunition of a pneumatic weapon, a CO2 weapon or a spring-loaded weapon, wherein the projectile is made of a mixture of metal and plastic formed by means of extrusion and has an injection point for the metal-plastic mixture, the surface of which differs from an adjacent surface of the projectile. 
     
     
         10 . The projectile according to  claim 9 , comprising a tail provided with the injection point, wherein in particular the injection point surface differs from an adjacent surface of the projectile at least in the region of the tail. 
     
     
         11 . The projectile according to  claim 9 , the surface of which is mechanically and/or chemically treated at least sectionwisely, in particular coated, in particular lacquered or electroplated. 
     
     
         12 . Ammunition for a pneumatic weapon, a CO2 weapon or a spring-loaded weapon, comprising a projectile according to  claim 1 . 
     
     
         13 . Method for manufacturing a projectile for ammunition of a pneumatic weapon, a CO2 weapon or a spring-loaded weapon, in which plastic granules and metal powder are provided, the plastic granules and the metal powder are mixed and then introduced by means of extrusion into an injection mold forming the outer shape of the projectile. 
     
     
         14 . The method according to  claim 13 , wherein the plastic granules and the metal powder are mixed to provide a mixture comprising metal and 2 to 15% by weight of plastic, based on the total weight of the projectile.
