Cryogenic Equipment Manufacturer — Deflashing, Deep Treatment & Freezing
India's First Choice for Deep Cryogenic Treatment
CryoNet designs, manufactures and commissions custom cryogenic equipment — from deflashing machines and deep cryogenic treatment systems to IQF freezers and cryogenic grinders — for the automobile, machine tool, pharmaceutical, food and aerospace industries.
What Is Cryogenic Equipment, and Why It Matters
Cryogenic equipment uses controlled exposure to extremely low temperatures — as low as −196°C with liquid nitrogen — to change how a material behaves, without adding heat, chemicals, or abrasives. The same underlying principle powers five very different outcomes: brittle flash that shears away cleanly, metal that resists wear for longer, food that freezes without losing texture, and rubbery material that grinds into a fine, pure powder.
At CryoNet, every machine is built in-house at our Surat facility and configured around the customer's part geometry, material, and production volume — not sold as a generic, one-size-fits-all unit.

Our Cryogenic Equipment Range
Five machine categories, each engineered in-house and customised to your part size, batch volume, and process requirement. Full details for every machine below.
Cryogenic Deflashing Machine
Tumbling-barrel machines that freeze rubber, plastic, and die-cast parts to embrittle the flash, then mechanically shear it off — leaving the part undamaged.
- Process TempUp to −196°C
- Flash Removal~100%
- Best ForRubber, plastic, zinc die-cast
Spin Tear Trim Deflashing
A controlled spin-and-tear mechanism finishes complex, thin, or internal flash that standard tumbling can't reach — ideal for intricate moulded geometries.
- ActionSpin + Tear + Trim
- FinishClean, residue-free edge
- Best ForComplex / inner flash parts
Deep Cryogenic Treatment System
Computer-controlled chambers that cool tools, dies, and components to ultra-low temperatures, refining the metal's crystal structure for longer wear life.
- Process TempUp to −190°C
- Result2–5× wear life improvement
- Best ForTools, dies, machine components
IQF Freezers (Individual Quick Freeze)
Continuous-flow cryogenic tunnels that freeze food items individually within minutes, locking in texture, colour, and shelf life without clumping.
- Freeze TimeMinutes, not hours
- OutputFree-flowing, individually frozen
- Best ForFood, seafood, fruits & veg processors
Cryogenic Grinding / Pulverising System
Liquid-nitrogen-cooled grinding lines that embrittle heat-sensitive or rubbery material before milling, producing finer, purer powder with no thermal degradation.
- Process TempSub-zero, pre-grind cooling
- OutputFine, uniform powder
- Best ForRubber crumb, spices, plastics, resins

Freeze it brittle, tumble it clean
Our cryogenic deflashing machines use liquid nitrogen to rapidly cool moulded rubber, plastic, and die-cast parts. The thin flash carries far less mass than the part itself, so it embrittles and crystallises first — opening a window where mechanical tumbling shears the flash away cleanly without touching the part underneath.
How it works
- Parts are loaded into a rotating barrel and cooled toward −196°C with liquid nitrogen
- Differential embrittlement makes the flash brittle while the part stays within its safe range
- Controlled tumbling — with steel or ceramic media when needed — shears off the brittle flash
- Parts return to ambient temperature with original physical properties fully restored

Reaching the flash that tumbling can't
Some flash sits in deep grooves, internal bores, or dimensionally complex pockets where standard barrel tumbling can't make consistent contact. Our spin-tear-trim units add a controlled rotational tearing action that reaches into these difficult zones, finishing parts that would otherwise need manual hand-trimming.
How it works
- Parts are held and spun against a calibrated trim mechanism after cryogenic embrittlement
- Controlled tearing action pulls thin, inner flash away from complex part geometry
- Works as a precision follow-up stage to bulk cryogenic deflashing
- Eliminates hand-trimming for hard-to-reach internal flash lines

India's first choice for deep cryo treatment
Our DCT chambers gradually cool tools, dies, and components to ultra-low temperatures, holding them there before a controlled return to ambient. This refines the underlying metal's crystal structure — converting retained austenite to martensite and precipitating fine carbides — for measurably longer wear life and better dimensional stability.
How it works
- Programmable, gradual cooling avoids thermal shock to the component
- Components are held at deep cryogenic temperature for an extended soak period
- Controlled ramp back to ambient, often followed by a tempering cycle
- Process is permanent — the gain stays with the part for its working life

Lock in freshness, item by item
Our IQF tunnels move product through a continuous cryogenic freezing zone, freezing each piece individually rather than as a block. Because each item freezes within minutes, ice crystal formation inside the cells stays minimal — preserving texture, colour, and nutritional quality far better than slow conventional freezing.
How it works
- Product moves on a continuous belt through a cryogenic spray or immersion zone
- Liquid nitrogen or CO₂ rapidly drops surface and core temperature
- Individual pieces freeze separately, staying free-flowing for easy packing
- Fast freeze rate minimises cell damage, preserving quality and shelf life

Finer powder, without the heat damage
Conventional grinding generates friction heat that softens rubbery or heat-sensitive material, leading to clogging, oxidation, and coarse particle size. Our cryogenic grinding lines chill the feed material with liquid nitrogen first — making it brittle enough to shatter cleanly under the mill, producing finer, purer powder in a single pass.
How it works
- Feed material is pre-cooled with liquid nitrogen to embrittle it before milling
- Brittle material fractures cleanly instead of smearing or melting under friction heat
- In-line nitrogen injection keeps grinding chamber temperature low throughout the run
- Produces a finer, more uniform particle size with no thermal or oxidative damage
