  • Process for joining a shell with a cartridge case
    Patent number: 4359925
    Abstract: An improved process for joining a shell having a plastic base portion to a cartridge case within a joining region. The joining region extends along a plastic base portion of said shell when it is inserted into the neck portion of the casing and has an upper and lower limit. The base portion is being axially inserted into the neck portion of the casing while being subjected to a relative rotational movement. A glueing or synthetic substance having flow capability is introduced into the neck portion of the casing. This plastic or glueing substance after hardening adheres more strongly to the inner surface of the neck portion than on said plastic base portion.
