The  Tumbleblast  Cryogenic  Deflashing  Machine from    Cryonet,  Surat  is  specially  designed  to deflash rubber and zinc-aluminum parts. 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.


Parts  that  have  thin  flash  can  be  quickly  and thoroughly  cryogenically  deflashed.  This  process is  exceptionally  good  at  removing  the  inner dimensional  complex  flash  that  can  not  be removed by any other method.

What is Cryogenic Deflashing?
The 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 media  is thrown by  rotation of barrel and  thus deflashing is done.
