NITROFREEZE® Cryogenic Deflashing and Deburring is a batch finishing process which employs cryogenic temperatures, tumbling, and polycarbonate media blasting to remove residual flash and burrs from molded or machined parts. The process is best suited for plastics and rubbers though metals with fine machine burrs can benefit as well.
The cryogenic deflashing process removes residual flash from molded plastic or rubber components. Flash appears when material leaks between the surfaces of two molds. Flash along parting lines or at ejector pin sites can be removed with cryogenic deflashing.
Cryogenic deburring offers a batch solution to removing burrs created during machining operations. Burrs appear as small bits of residual material or a raised edge following operations such as grinding, drilling, milling, engraving or turning.
The Deflashing and Deburring Process
During processing, parts are tumbled on each other and blasted with non-abrasive media in a cryogenic atmosphere. The combination of tumbling and blasting serves to remove flash and burrs. View an illustrated step-by-step.
Our cryogenic deflashing and deburring process has sucessfully cleaned most plastics and rubbers.
- Acrylic (eg. Lucite)
- CTFE (eg. Kel-F)
- HDPE (eg. Alathon)
- Polyamide (PA) (eg. Nylon)
- Polyoxymethylene (POM) or Acetals (eg. Delrin, Celcon, Ramtal, Duracon, Kepital and Hostaform)
- Polycarbonate (eg. Lexan, Makrolon)
- Polyphenylene sulfide (PPS) (eg. Ryton)
- Polyether Imide (PEI)
We’re here to help.
Representatives are available to discuss your project requirements and assist you in choosing the appropriate finishing solution for your parts.
If the parts are deemed viable candidates for the process, sampling can be performed to prove out the concept. A consultation is free so we encourage you to reach out.
We are always happy to talk with you.
