Rubber loses its elasticity after being rapidly cooled at cryogenic temperature by liquid nitrogen (or liquid carbon dioxide), it first become hardened then embrittled and finally crystallized. The flashes become embrittled much quicker compare to parts due to low thickness, creating the difference in hardness and embrittlement of rubber parts and flashes.

At this stage a mechanical impact is given by tumbling in a barrel and / or blasting with media by rotation of barrel and thus deflashing is done.

The process uses liquid nitrogen, barrel rotation and media (steel balls, ceramic balls or other suitable media) in varying combinations to remove the flash in a highly precise, economical and expedient manner.

As flashes have a much thinner surface area compared to the product , the flashes "FREEZES" very quickly and become brittle. The tumbling action—combined with the impact of the media—removes the flashes without damaging the part itself. Parts that have thin flash can be quickly and thoroughly deflashed. This process is exceptionally good at removing the inner dimensional complex flash that can not be removed by any other method.

After the process is complete, parts are returned to ambient temperature and their properties returns too. The physical properties of the moulded rubber parts are not affected during the deflashing process. Cryogenic deflashing leaves a clean part—with no dust or other residue remaining ; with nearly 100% flash removal. Cryogenic deflashing is ideal for die cast metal parts, complex rubber parts, plastic parts, medical parts etc. due to its unique features of high productivity, high precision and low cost.

■ We offer Cryogenic Deflashing service to customers for their rubber and plastic components. The Process eliminates the concern of supplying parts of visibly different quality to the customer.
