A method of forming a molded device, such as a stopper, requiring minimal post-molding processing includes providing a four-plate mold assembly (52) having top plate (54), a sprue/vent plate (56) including a core portion (62), a main plate (58) including a recess (66) defining a mold cavity (68) having a contoured surface (70), and a bottom plate (60), closing the mold assembly (52) such that the core portion (62) enters into the recess (66) in the main plate (58) to define a space (72) corresponding to the shape of the stopper (10, 110) to be molded. A polymeric material is introduced into the mold cavity (68) to form the stopper (10, 110). A barrier layer (14, 114) can be inserted between the main plate (58) and bottom plate and adhered to the molded device (10, 110). The plates are opened and the molded device is removed.

A garment worn by a wearer has an exterior shell and an interior shell with various impact absorbing material between the exterior shell and the interior shell. The impact absorbing material includes multiple structures, such as rods or filaments, capable of deforming when force is applied then returning to its state prior to application of the force. In various embodiments, the impact absorbing material is manufactured using injection molding to allow positioning of various structures in the impact absorbing material relative to each other during manufacture. During manufacturing, one or more living hinges are included in portions of the impact absorbing material to allow certain portions of the impact absorbing material to be accurately positioned relative to each other. Other manufacturing methods may be used, such as three-dimensional printing may be used to include structures in the impact absorbing material.

Sacrificial additively manufactured molds having a dissolvable material for use in thermoplastic injection molding processes at plastic melt temperatures in the range of 70-450 degrees C. and injection pressure in the range of 0.2-400 MPa.

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.
