Cryogenic Chambers for Tool Life Enhancement & Precision Metal Treatment
Cryogenic Chambers are industrial cryogenic treatment systems designed to improve tool life, wear resistance, and dimensional stability of metal components. By exposing tools, dies, and precision parts to controlled ultra-low temperatures using liquid nitrogen, cryogenic treatment alters the internal microstructure of metals, resulting in permanent performance improvements.
Manufactured by Comet Environs, our cryogenic chambers are engineered for industrial reliability, repeatable thermal cycles, and long-term continuous operation.
Cryogenic Chamber – Process and Working Principle
Cryogenic treatment is a controlled sub-zero thermal process in which components are gradually cooled to temperatures as low as –190°C using liquid nitrogen (LN₂). After reaching the target temperature, parts are soaked for a defined duration and then returned to ambient or elevated temperatures at a controlled ramp rate.
This controlled cryogenic processing results in:
Conversion of retained austenite into martensite
Improved carbide precipitation and distribution
Reduction of residual and internal stresses
Increased hardness and wear resistance
Unlike conventional heat treatment, cryogenic treatment affects the entire material structure, delivering permanent and uniform performance improvement.
Cryogenic Chamber Benefits – Proven Industrial Results
Cryogenic treatment delivers consistent and measurable gains in tool life and productivity across industrial applications.
| Sr. No. | Application | Average Life (Before) | Life After Cryogenic Treatment | Improvement Ratio |
|---|---|---|---|---|
| 1 | Copper resistance welding tips | 2 weeks | 6 weeks | 3.0× |
| 2 | Progressive metal-working dies | 40,000 hits | 250,000 hits | 6.25× |
| 3 | Blanking of heat-treated 4140 & 1095 steel | 1,000 pieces | 2,000 pieces | 2.0× |
| 4 | Broach for C-1020 steel torque tube yoke | 1,810 parts | 8,620 parts | 4.75× |
| 5 | Broaching forged connecting rods | 1,500 parts | 8,600 parts | 5.73× |
| 6 | Gang milling T-nuts (C-1018 steel) | 3 bars | 14 bars | 4.67× |
| 7 | AMT-38 cut-off blades | 60 hours | 928 hours | 15.4× |
| 8 | 33-inch trimmer blades | 28 hours | 140 hours | 5.0× |
These performance gains lead to:
Reduced tooling replacement frequency
Improved machining consistency
Lower production downtime
Reduced overall manufacturing cost
