Electric Cryogenic Deflashing Machine, Brand Name : PRC

Cryogenic deflashing technology—uses a system whereby rubber or plastic parts are placed in a perforated stainless-steel barrel located in the machine chamber, exposed to extremely cold temperatures (achieved with the use of liquid nitrogen, which is up to -130℃) and then tumbled in barrel and blasted with a polycarbonate media motivated by a high speed(up to 7000rpm/min) wheel. Because the burrs/flashes have a much thinner surface area comparing with their mass, burrs/flashes “FREEZE” very quickly and become brittle while the mass still not. The tumbling action—combined with the impact of the media—removes the burrs without damaging the part itself.
After the process is complete, parts are returned to room temperature and their properties returns too. The physical properties of your moulded rubber parts are not affected during the deflashing process.
Cryogenic deburring leaves a clean part—with no dust or other residue remaining—with nearly 100% burr removal.
Cryogenic trimming and deflashing are ideal for die cast metal parts, complex rubber parts, precision electrometric parts, medical parts and micro electronic parts due to its unique features of high productivity, high precision and lower cost.
