If you want to improve part quality and reduce flash defects our processes will prove advantageous to you. Nitrofreeze offers manufacturers and injection molders a batch method to remove residual flash from molded plastic and rubber parts. Our service provides consistent, repeatable and cost-effective results. Every new part begins with a free Pre-Production Engineering Evaluation — see our Five R’s evaluation process for how we prove and document the recipe before quoting production.
Cryogenic Deflashing Services
Nitrofreeze® Cryogenic Solutions
Who uses cryogenic deflashing?
Nitrofreeze provides flash removal services to molders and OEM manufacturers that make injection molded, extrusion molded and compression molded parts.
What materials can be deflashed?
Most rubbers, plastics, and composites have been successfully deflashed with our cryogenic process.
Common candidates include silicone rubber, FKM, EPDM, neoprene, LSR, fluorosilicones, ABS plastic, PEEK, Delrin and other acetals, nylon, PPS, HD/PEs, PEIs including Ultem, Vespel, polypropylene, zinc, and polycarbonate.
How do we remove flashing from the parts?
We provide multiple methods for deflashing plastic molded parts. The location and intensity of the residual mold flash will determine which process is the most suitable.
Injection Molded Plastic Part Deflashing
Our cryogenic deflashing service offers a fast and repeatable process to remove flash from plastic parts. Through freezing, tumbling and blasting polycarbonate media at your injection molded plastic parts, we are able to remove residual mold flash time and time again. We have processed injection molded parts from manufacturers in the medical, automotive, electronics, defense and aerospace industries.
Rubber Deflashing
The Cryogenic Deflashing process was originally created to remove mold flash from rubber parts. We are able to deflash rubber parts that are injection molded, extrusion molded and compression molded. We have processed parts made of various durometers. We typically deflash rubber parts made of EPDM, neoprene, Viton, Buna-N, nitrile, natural gum, SBR, butyl, and other elastomers.
Silicone Rubber Flash Removal
Our Deflashing Service is often used by molders who work with silicone rubber. Silicone rubber, by its nature, is very viscous causing it to flash during the molding process. The Nitrofreeze Deflashing service removes mold flash from silicone rubber parts. We deflash parts made of liquid silicone rubber and even special blends of silicone rubber that include conductive fillers such as silver, graphite, nickel.
Extend Mold Tooling Life & Reduce Costs
Cryogenic deflashing can extend the overall lifetime of mold tooling. Minor wear that causes flash can be remediated with cryogenic deflashing. This finishing step reduces downtime, and the costs associated with replacing or rehabilitating worn mold tooling. It is a cost-effective method when compared to hand deflashing and new mold tooling investments.
Our Plastic, Silicone and Rubber Deflashing Service Protects Parts Integrity
Cryogenic Deflashing is a fast and efficient process that provides complete removal of mold flash without affecting the surface finish. Therefore, it is a safe, clean and cost-effective alternative to traditional methods.
Parts are placed in a chamber, cooled, tumbled and impacted with plastic polycarbonate media. Mold flash is removed quickly and cleanly. No dust or residue remains after deflashing.
Fast & Affordable Cryogenic Deflashing
Cryogenic Deflashing is more cost-effective than labor-intensive hand deflashing by a significant margin. The cost to process parts can range from less than .01 cent to several dollars apiece. General rule of thumb: cost is between 10% and 20% of the value of the part, although each part must be considered on its individual characteristics.
Turnaround for delivery of our deflashing service is as little as two days after receipt. We also offer same day and one-day service for a small premium. Large volume orders typically require more time to process. See what to know before you send us parts for minimum order, part sizes, materials we don’t take, and how the first run works.
No Cryogenic Deflashing Job Is Too Large or Small
Nitrofreeze supports prototype molders that produce small quantities, as well as high volume molders with large production quantities. We process parts that range in sizes from 0.025” with thin walls to much larger parts that measure across many inches. No job is too large or small for our process to handle.

Cryogenic Deflashing Gallery
Our Cryogenic Deflashing process utilizes gaseous nitrogen as a cryogen to freeze the parts while they are tumbled and blasted with plastic media. This process is able to remove mold flash from difficult to reach areas including cross-holes, blind holes and other difficult geometries.
Dry Ice Deflashing
Our Dry Ice Deflashing process allows mold flash to be removed from difficult geometries such as internal holes, cross-holes, blind holes, small slots and crevices. The process utilizes high pressure air to blast dry ice media at the areas requiring deflashing.
Send Us Your Cryogenic Deflashing Samples
Nitrofreeze is pleased to provide a no-cost or no obligation assessment of your mold flash problem.
We can review part drawings, photos and actual samples of molded parts.
If the parts are deemed a good candidate 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.
