Abstract
The present disclosure relates to a system for forming a cartridge case, the system including a series of stages, each stage comprising a sequential location in the system, and each stage comprising a process step, wherein each process step is synchronized to occur within a substantially simultaneous stage interval, the stages including: an annealing stage, a head forming stage, and a taper stage. The present disclosure also relates to a method for manufacturing a cartridge case, the method including: receiving a single cartridge case at a time in a first direction into an annealing chamber through a first opening, passing an alternating current through an inductive coil for a certain time period to heat the cartridge case, releasing the cartridge case from the annealing chamber in the first direction through a second opening, and performing a forming step on the cartridge case.
