       BRAVO Jet machine is a versatile machine designed to remove flashes inherent in molded rubber products and zinc-diecast products. It has achieved this purpose by taking advantage of the characteristic brittleness of rubber and zinc-alloy in low temperature environment which is generated by the infusion of liquid nitrogen (LN2)

      The freeze-deflashing method by opted BRAVO jet machine is now an alternative to traditional stamp methods, This freeze deflashing method is able to trim flashes of molds by freezing them first then removing their embrittle portions.

      For instance, rubber loses its elasticity after being cooled, it first become hardened then embrittled and finally cristalized, Rubber would be so easily reshaped, particularly under the embrittling temperature, by a slight deforming of the material.

      As the molded rubber products (or zinc-alloy diecastings) are filled into the polygonal barrel, the liquid nitrogen sprays onto the parts, effectively freezing the flash, A turbine style blast wheel spins at speeds from 4500~7200RPM, propelling the Cryogenic-grade plastic media at the parts, The impacting pellets cleanly break off the flash without damaging the rubber parts.
