Dry Ice Deburring Services

A piece-by-piece process that removes burrs from intricate machined plastic parts using dry ice.

For Hard To Reach Areas

i3 Micro CleanDry Ice Micro Deburr removes burrs on the exterior and interior of parts, and cleans cross-holes and slots within the parts. The process is effective in removing minor burrs from parts.

Dry Ice Micro Deburring is an ideal solution for parts that have inconsistent burrs. Since the parts are deburred separately, attention is given to the areas of concern. If a work holder is required, Nitrofreeze is expert in developing low-cost fixtures to support the deburring of parts.

Use on Many Materials

Dry Ice Micro Deburring is available for most machined and molded parts, especially on engineered materials and composites.

We have many cases of successful burr removal on parts machined from plastics, polymers, nylons, delrin, Teflon, polypropylene, polycarbonate, ABS, PET, HDPE, PEEK, DAP, Tefzel, PPS, Viton, Torlon, CTFE, Liquid Crystal Polymer, PH Stainless Steels, Aluminum and Beryllium Copper.

Lower Cost & Higher Quality

Dry Ice Micro Deburring is more cost-effective than labor- intensive hand deburring by a significant margin – and it yields superior quality. Our process produces consistent part-to-part results, unlike variations produced by individual operators attempting hand deburring.

The cost to deburr parts as a general rule of thumb is between 10% and 20% of the value of the part, although each part must be considered on its individual characteristics.


Solid blocks of dry ice (CO2) or dry ice pellets are used as a non-abrasive media. The blasting system is connected to a compressed air source that achieves blasting rates as high as 150 PSI. Once the dry ice impacts the surface, it sublimates, causing it to expand 800 times its original size. This allows the burrs to be easily removed.

Send Us Your Samples

Nitrofreeze is pleased to provide a no-cost or no obligation assessment of your machine burr or mold flash problem.
We can review part drawings, photos and actual samples of machined and molded parts.
If the parts are deemed a good candidate for the process, samples can be processed for a nominal fee. We can also evaluate parts on a not-to-exceed cost basis if you have a target cost in mind.

We are always happy to talk with you.
