Cryogenic Deflashing

Cryogenic deflashing is a process that uses the extremely low temperature of a cryogen such as liquid nitrogen (LIN) to remove flash. The process includes using LIN to freeze and embrittle the flash on the rubber or plastic parts, causing it to break away by applying mechanical stress through tumbling and/or simultaneous media blasting. When combined with media blasting, tumbling enables uniform impingement of the blast media over the entire surface of all parts, removing both internal and external flash.
