Nitrofreeze® provides ISO 9001:2015 and ITAR registered contract deburring services for plastic and metal CNC machined parts. These deburring processes remove residual burrs left over after machining operations with consistent, repeatable and cost-effective results.
Cryogenic Deburring Services
Nitrofreeze® Cryogenic Solutions
How do we Deburr the Parts?
We offer multiple cryogenic processes to remove machine burrs. The formation, location and intensity of the burr requiring removal will determine which deburring process is the most ideal fit.
Our Cryogenic Deburring process utilizes tumbling, freezing and a cryogenic-grade PC media blasting to remove burrs from CNC machined parts.
The Cryogenic Tumble Deburring process removes burrs on the external geometry of machined parts through freezing and tumbling without the use of media blasting.
In addition, our Dry Ice Deburring process removes hard to reach burrs via high pressure blasting of dry ice as a media. This form of deburring is used on high value parts since only one part can be processed at a time.
Who uses Nitrofreeze® Deburring?
Nitrofreeze® is a go-to partner for machine shops and OEM manufacturers. The facility is outfitted with a full range of cryogenic deburring systems to support manufacturers from prototype stages to large production runs. Every new part begins with a free Pre-Production Engineering Evaluation — see our Five R’s evaluation process for how we build, refine and archive the recipe before quoting production.
What Materials can be Deburred?
Nitrofreeze® processes are effective in deburring most polymers and plastics. Even metals with fine burrs (less than 0.008″ thick) have proven successful candidates for processing. PEEK, nylon, acetals (Delrin®), polypropylene, polycarbonate, PTFE (Teflon®), PET, (HD/LD)PE, PVC, ABS, stainless steel, copper, and aluminum are materials frequently deburred with Nitrofreeze® processes.
Our Deburring Service Protect Parts Integrity
Cryogenic Deburring does not affect the surface finish or geometry of the part. The deburring tool provides a safe, clean and cost-effective alternative to traditional hand, vibratory or tumbling methods.
Parts are placed in a chamber, cooled and impacted with polycarbonate media. The machine burrs are frozen and removed quickly and cleanly by the passing non-abrasive polycarbonate media. Little to no dust or residue remains. Only offensive burrs are removed. Edges are maintained without rounding or other material removal.
Our Deburring Process Can Be Used On Many Materials
Our cryogenic deburring service works on plastics, polymers, nylons, delrin, Teflon, polypropylene, polycarbonate, ABS, PET, HDPE, PEEK, DAP, Tefzel, PPS, Viton, Torlon, CTFE, Liquid Crystal Polymer, PH Stainless Steels and Beryllium Copper.
The computer-controlled process generates repeatable and reliable results. Many medical devices and other high value precision components are included in Nitrofreeze’s vast array of successful deburring applications.
Cryogenic Deburring Is Economical & Offers High Quality
Cryogenic Deburring is more cost-effective than labor-intensive hand deburring by a significant margin – and it yields superior quality. Our automated deburring service produces consistent part-to-part results, unlike variations produced by individual operators attempting hand deburring.
The cost to deburr parts can range from less than .01 cent to several dollars per piece. A general rule of thumb: the cost is between 10% and 20% of the value of the part, although each part must be considered on its individual characteristics and geometries.
Cryogenic Deburring Removes Recessed Burrs in Blind and Through Holes
Using a range of non-abrasive polycarbonate media that is sized from 0.015” (smallest) to 0.060” (largest), Nitrofreeze is able to reach inside the most demanding part geometry to remove internal machine burrs. We are experts in developing low-cost custom fixtures to ensure burr removal in blind and through holes and other recessed areas of parts geometry.
Fast Deburring Service
Turnaround for delivery of Cryogenic Deburring is as little as two days after receipt. Nitrofreeze offers same day and one-day service for a small premium. Large volume orders typically require more time to process. Our cryogenic deburring minimums, lead times and part sizes are published in full.
No Deburring Job Is Too Large Or Small
Nitrofreeze supports prototype shops that are working with small quantities as well as high volume production quantities. Part sizes vary from 0.025” with thin walls to much larger parts that measure in inches and have more mass.

Send Us Your Deburring Samples
Nitrofreeze is pleased to provide a no-cost or no obligation assessment of your machine burr problem.
We can review part drawings, photos and actual samples of machined parts.
If the parts are deemed good candidates for the process, Nitrofreeze processes the first sample lot free as part of our Pre-Production Engineering Evaluation — additional lots, measurements or inspection reports are quoted separately. 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.
