Process spotlight – Cryogenic deflashing
Additional insight provided by Jordan Anderson of Nitrofreeze in Worcester, MA. Nitrofreeze offers both cryogenic and dry ice deflashing and deburring services. Process: Automated and programmable batch process utilizing cryogenic temperatures, basket tumbling, and non-abrasive media. The cryogenic-grade polycarbonate media varies in size from a 0.004″ blend to 0.060. Batch capacity: Batch processing...

Cryogenic Batch Deflashing
Cost-effective deflashing method utilizing a combination of cryogenic temperatures, non-abrasive media, and tumbling.
Thermal energy deflashing
Thermal energy deflashing uses transient burning
of the mixture of O2 and H2 (or O2 and CH4) to burn
out flash.
| Cryogenic Deflashing | Thermal Energy Deflashing | Magnetic Abrasive Deflashing | Blast Deflashing | Ultrasonic Vibration Deflashing |
|---|
| Process | Cryogenic temperatures, tumbling, and blasted PC media | Transient burning of the mixture of O2 and H2 (or O2 and CH4). | Magnetically-driven steel pins abrade the part surface. | Blasted metal powder media. | Ultrasonic vibration induced water serves to remove residual material. |
| Suitability | Suitable for most polymers and rubbers. | Can burn part surfaces. Allowable for plastic and rubber parts with no aesthetic tolerance. | Applicable for parts produced from low elongation material (<2%). | Produces rough finish. Suitable for parts without aesthetic requirement. | Suitable for most plastic and metal components. Not suitable for rubber parts due to toughness. |
| Advantages | Non-abrasive. Good for parts with strict flash and aesthetic tolerances. Can support large volumes per cycle. | Relatively quick cycle time, which suits mass production. More appropriate for metals. | Two to three minute cycle time. Steel pins can be reused. | Can be designed for an automatic line with a transport belt as well as as a manual spray gun. Relatively low cost. | Effect for plastic materials shows good results without damaging the part surface. |
| Disadvantages | In-house integration cost is relatively high. | Plastic component can be burned on all surfaces. Can’t be used for parts with a high-quality surface requirement. | Effect not good for plastic and rubbercomponents because of the “softness” of the flash. | Highly abrasive. Not suitable for parts with a high aesthetic surface requirement. | Can struggle deflashing parts with difficult geometries. |
