Cryogenic Deflashing
Cryogenic Deflashing
(OP)
I am trying to learn more about our cryogenic deflashing process. Does any one know of an article or book that details this process? In paticular we mold rubber, silicone, and urethane. We are having the most trouble with the silicone compounds. Queations I have would be: What is your ambient temp of the cryo room? Rel. Humidity?? How cold do you go for small silicone parts?? How long do you blast??
Any info will be helpfull. Thanks in advance.

Is there some specific info, or search engine to use? I have Goggled for Cyro Deflash, and found an abundant amount of suppliers for a machine. We already have two of them, but the process has never really been understood. Sure we can produce parts with no flash, but are we doing it efficiently? The guy that was in charge of it before me went by the standard of longer blast time, not colder.
I was looking for some "ballpark" numbers. Currently our "controlled" c-mec room is at 60% RH, that seems kinda high to me, cause the machine frosts up and you can't open the doors when it gets humid out. Now we just run the machines at 3rd shift.
So, again, if any one has any info, I would greatly appreciate it.
Thanks,
Jamie
