Estimating the term…
The present invention pertains to the field of the arms industry and metallurgy, and also to the fields of materials engineering and chemical engineering. More specifically, the present invention refers to a novel ammunition cartridge comprising reinforced polymer and the manufacturing process thereof. The ammunition cartridge serves for receiving the gunpowder so that explosions can occur inside the weapon barrel. The technology proposed reduces the quantity of components to be pre-manufactured and assembly processes on the product, producing a full cartridge, directly upon injecting the thermoplastic, and can also use bi-component injection. With this, the portion of the collar ring can be made entirely of fiber-reinforced polymer material, which reduces the weight of the item and is beneficial for the useful life of the weapon in the bolt region.
An ammunition cartridge comprising a head portion and a body portion, said head portion having one end formed by a ring (3), said ammunition cartridge (1) being characterized by the body portion and the head portion made in a single piece and comprising a metal insert (2) in the head portion.
