The VULCANO is an innovative resonance induction annealing machine for cartridge bullet cases. VULCANO is designed to eliminate neck and shoulder case-hardening resulting from full-lengh resizing after repeated firings.
It restores the ductility o f the case by reducing internal stresses in the brass, making it easier to stretch under pressure rather than crack.
With VULCANO is possible to perform the annealing from the smallest shells to the larger ones such as the .50 BMG obtaining the same process for all the shells. The VULCANO applies, to a work hardened area of brass, a localized heat by magnetic induction and energy of that heat will cause the grain size of the metal to grow. As this happens, the material loses strength (relaxing heat treatment) and regais its tolerance fro stretching without braking. The Annealing process depends for the material, temperature and time applied.
VULCANO is the first annealing machine where you can play in total freedom all these parameters.
