Cryogenic Deflashing Machine for Rubber Trimming by Nitrogen PG-40T
Product Description
PROCESSING PRINCIPLE
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.
FUNCTIONS
Our machine is widely used in removing the flashed of small rubber and plastic parts like O-rings, gaskets and other molded parts.
With the cryogenic processing technology, the flashes are firstly freeze and then shot down the high-speed projection media (Polycarbonate blast). The surface quality of molded rubber and plastic rubber parts can be improved greatly.

ADVANTAGES
Cryogenic deflashing provides various advantages over manual deflashing and other traditional deflashing methods.
The process maintains part integrity and critical tolerances.
Since it is a batch process, the price per piece is far less as many more parts can be processed in a given amount of time.
Cryogenic deflashing extends mold life. Rather than replace or repair a mold (which typically involves downtime and high cost), the parts can be deflashed. This is typical of parts molded at the end of their product lifetime.
The process is computer controlled, therefore removing the human operator variable from the process.
The process offers consistent results from lot to lot.
Cryogenic deflashing is non-abrasive.
The cost per part is generally well below any alternative technique.
