Cryogenic deflashing technology—uses a system whereby rubber or plastic parts are placed in a machine chamber, exposed to extremely cold temperatures (achieved with the use of liquid nitrogen) and then tumbled in barrel and blasted with a polycarbonate media.

Because the burrs/flashes have a much thinner surface area comparing with their mass, burrs/flashes “FREEZE” very quickly and become brittle. 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. Cryogenic deburring leaves a clean part—with no dust or other residue remaining—with 100% burr removal.

Cryogenic deburring and deflashing are ideal for die cast metal parts, complex rubber parts, precision electrometric parts, medical parts and micro electronic parts.

PROCESSING PRINCIPLE
With the decrease of the temperature, rubber/plastic parts enters into hardened, brittle, and crystallized process, its flexibility is gradually lost. It is easily broken by external force when it is under brittle temperature. Flash of the molded products is generally much thinner than finished product itself, it become brittle earlier than product in the low temperature. Cryogenic deflashing machine applies this principle, works in the time range when flash is brittle while products still keeps its flexibility, hit the flashes by high speed projected special plastic media, clear out the brittle burr. The flashes can be easily removed and the product not be damaged.

Product Feature
Function
Our machine is widely used in removing the flashed of small rubber and plastic parts like Orings, gaslets and other molded parts.
With the cryogenic processing technology, the flashes are firstly freezed and then shoted down the high speed projection media(Ploycarbonate blast). The surface quality of molded rubber and plastic rubber parts can be impoved greatly.

Main benifits
High efficiency: The machine can replace about 60-80 worker to removing the flashes.

High precision: It can remove small and hiddened falshes which cannnot be removed by handworkers and improve precision of the products.
Low cost: It also has a feature of lower cost comparing with processing the parts by handworkers.
