Cryogenic Deflashing Process

1: Parts are staged for production with the volume of the order broken down into batch sets. Shown here an operator loads a batch of parts into the basket to be submitted for processing.
2: The basket is seated onto rails in a stainless steel lined chamber. The operator then inputs or bar code scans the process recipe for the specific part. Process parameters are populated in the system and the operator may begin the cycle.
3: Once the programmed temperature is reached, basket tumbling begins and parts are simultaneously blasted with a cryogenic grade polycarbonate media. Throw wheel speed (controlling media velocity) and basket rpm (controlling tumbling rate) are both computer maintained to the pre-programmed recipe.
4: Blasting and tumbling continue for the designated cycle duration
5: Once blasting stops, the parts continue to tumble for a brief period to remove any residual deflashed material and to dislodge any remaining media. Processed parts (in the basket) are removed from the chamber.
6: The now deflashed parts are emptied into a net that is suspended in a holder and blown with compressed air to remove any remaining flash particulate.
7: Parts are set in a wired mesh containment to air dry in ambient temperature as they await final inspection.

Send Us Your 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 machined 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.
