Cryogenic Deflashing

Cryogenic de-flashing is the process by which components are subject to a rapid cooling effect to embrittle them, with a stream of polymer particles then propelled at the component to remove moulding flash and burrs.  Typically, this process involves cooling the components to temperatures from -70°C to as low as -120°C so it is imperative that the media used in this environment can withstand, not only these extremes of temperatures, but can do so while maintaining structural integrity and the impact energy created by the propulsion systems.

Normally propulsion is achieved by wheel driven blast systems and vary in diameter from 240mm to 450mm, with wheel speeds ranging from 20,000 rpm to just 7,000 rpm.  At the Mac’Ants Group, we have a differing range of Polyflash compounds suitable for use in these applications, which are capable of withstanding these punishing operational conditions.
