Deburring and Deflashing

Cryogenic Deburring and Deflashing Frequently Asked Questions

Many of our customers ask us about our cryogenic deburring and deflashing process. They have many questions regarding how it works, what kind of burrs it can remove, and many others. Below are the most frequently asked questions we have received along with the answers that our customers need.

What Kind Of Burrs Can The Cryogenic Deburring And Deflashing Process Remove?

For the most part this process can remove light burrs. For example, if you can remove the burr with your finger, it is a good candidate for the process. Heavy burrs on plastics will most likely be removed but will be subject to longer cycle times. Heavy burrs on metals tend to roll or flatten but for the most part will not be removed.

What Materials Are The Most Suitable For Cryogenic Deburring And Deflashing?

While most plastics will have their burrs and flash removed by this process, some work better than others. In particular, ABS, Acetyl, Delrin, LCP, Neoprene, Nylon, PEEK, Polycarbonate, Polypropelyne, PTFE, Silicone, Teflon, Urethane, are well suited for this type of deburring and deflashing.

Will Cryogenic Deburring And Deflashing Remove Burrs From Metals?

Cryogenic Deburring and Deflashing will work on nonmagnetic materials. In particular we have had success running stainless steel, aluminum, aluminum zinc die-cast, and beryllium copper. It will work on other metals, but it relies heavily on how extreme the metal burrs are.

Will Cryogenic Deburring and Deflashing Harm The Structural Integrity Of Medical Parts?

This question gets asked time and time again. All materials have certain freeze points and we run our process above those points. Therefore, only the flash and or burrs are frozen and then removed by the cryogenic grade media. Our customers are more than welcome to check with their materials vendors to make sure that their materials will not be adversely affected.

How Does Cryogenic Deburring And Deflashing Effect External Threads And/Or Critical Tolerances?

Cryogenic Deburring and Deflashing is mainly a non-abrasive process. The cryogenic-grade media will typically remove the burrs and or flash only. The process generally will not damage the parts or adversely affect the part's structural integrity.
