Applications
Dry Ice for Metal Shrink Fitting and Cryogenic Engineering in Pakistan
Precision Metal Contraction for Pakistani Engineering Workshops
Precision engineering workshops in Rawalpindi and Karachi use solid CO2 at -78.5°C to cryogenically contract metal components. Cryo-contraction preserves metal grain structure — unlike high-heat welding which weakens alloys — delivering interference fits that hold permanently under operational loads.
High-Density Blocks for Heavy Duty
We supply highly compressed dry ice pellets that can be cut to fit custom bearing dewars and fuel tank sizes — delivered to engineering workshops in Rawalpindi and Karachi.Seamless Shaft & Bearing Fitting
Placing heavy gears, pins, or sleeve bearings in solid CO2 contracts their dimensions for press-fit assembly into tight housings. Engineering workshops across Rawalpindi, Karachi, and Lahore use this method for precision bearing installations.
Explosive Tank Inerting & Safety
Before cutting or welding fuel tanks in Pakistani automotive and industrial workshops, dry ice pellets dropped inside sublimate into inert CO2 gas — displacing explosive oxygen vapours and preventing dangerous combustion.
Asphalt Temperature Retention
Construction projects across Pakistan maintain hot asphalt and binders at ideal temperatures during long-distance transits between sites, using dry ice pellets to control heat emission rates.
