Deflash Rubber & Plastic Parts at −196°C with Zero Distortion
Liquid nitrogen, high-speed media blasting and precision barrel rotation remove flash cleanly from the most complex inner geometries — a process trusted since 1999 by Cryonet, Surat.
Cryogenic Deflashing Process Details
The Cryogenic Deflashing Machine from Cryonet, Surat is purpose-built to deflash rubber and plastic parts. Liquid nitrogen, barrel rotation and media — steel balls, ceramic balls or other suitable media — combine in varying ratios to remove flash precisely, economically and fast.
Load the parts
Moulded parts are placed in a perforated stainless-steel basket, which rotates inside a well-insulated blast chamber — keeping every part in motion through the treatment cycle.
Chill below glass transition
Liquid nitrogen is injected into the chamber while the basket rotates, evenly lowering part temperature until the rubber drops below its glass transition point and turns brittle.
Below glass transition tempBlast the brittle flash
A high-speed impeller directs plastic media at the tumbling parts inside the rotating basket. Travelling at speed, the media cleanly trims brittle flash — including inner, dimensionally complex flash no other method can reach.
Impeller speed up to 7,200 RPMSeparate media & finish
The machine separates reusable media from debris — flash and dust — and continues the cycle, leaving a high-quality, flash-free finished part ready for use.
What Materials We Can Deflash
Most rubbers, plastics and composites can be successfully and economically deflashed with our cryogenic deflashing service.

Criteria for Cryogenic Deflashing
Getting the best finish, speed and nitrogen economy starts upstream — at flash design and mould quality.
Keep it thin
Ideal flash thickness is around 0.1 mm. Thinner flash means a faster process, a better finish, and lower consumption of liquid nitrogen, power and time.
Avoid tear & trim design
Tear and trim designs should be avoided. Where unavoidable, shift the flash further away from the component to protect critical surfaces.
Consistency is everything
Correct, consistent moulding is the single most important factor for success. No machine can overcome or eliminate moulding defects — consistent input is the only path to consistent finished output.
