the process of cryogenic deflashing

For the freezing procedure of the batch, ultra-low temperature tiny drops of liquid nitrogen are injected to the loaded parts.

During the nitrogen’s fast physical state conversion from liquid to gas, the extracted energy causes shock-freezing of the burrs which reach the embrittled condition immediately.

The current moulded parts still remain rest-elastic, therefore no damages from coolness tension can take place. The shock-frozen burr – not solid and elastic as the  moulded part itself – can now be removed with high efficiency by the jet energy of blasing media.
