How to Remove Flash from NBR Rubber Rings at the Parting Line?

 Nitrile rubber (NBR) is widely used in precision sealing components for automotive, medical, and electronics industries due to its excellent oil resistance, wear resistance, and elasticity. However, under 60x electron microscopy, micro-flash at the parting line remains a persistent issue. Traditional manual or mechanical trimming methods risk product damage and suffer from low efficiency, failing to meet high-precision requirements.

NS-60 Cryogenic Deflashing Machine

To address this challenge, our technical team has optimized cryogenic deflashing technology using theNS-60 Cryogenic Deflashing Machine, paired with custom micro-perforated part baskets to prevent small components from being lost during processing. By precisely controlling freezing temperature, media flow rate, and deflashing duration, flash is efficiently removed, significantly improving surface smoothness to meet high-magnification inspection standards.
