In the cryogenic shot-blast deflashing process, our patented cryogenic grade polycarbonate media (CG) is blasted at rubber parts by means of a turbine blast wheel that spins at speeds of up to 6,000-10,000 RPM. The media impacts with the parts (frozen by means of liquid nitrogen) which are tumbled in the blast machine. Temperatures can reach -300° F (-184° C), effectively freezing the flash, or the excess where the mold halves meet, which is created during the rubber molding process.

This process will quickly deflash parts in an approximate 3-5 minute cycle. Once the parts emerge from the blast system and warm to room temperature, they are perfectly shaped with no signs of flash or damage.
