Why Dry-Ice for Galvanization Dry-Ice Cleaning?

Post-dip ash and dross cling to parts and fixtures. Hand scraping is slow and risks gouging the zinc layer; wet blasting on hot steel invites corrosion and slippery floors.

CO₂ pellets accelerated to high velocity flash-sublimate on impact. The thermal/acoustic micro-impulse shears brittle ash and dross off the surface without abrasive contact or moisture.

You preserve coating thickness, shorten touch-up, and keep the line moving. Less rework, safer floors, and faster fixture maintenance boost throughput and delivery reliability.

Key takeaways

  • Post-dip ash and dross cling to parts and fixtures.
  • CO₂ pellets accelerated to high velocity flash-sublimate on impact.
  • You preserve coating thickness, shorten touch-up, and keep the line moving.

Core Benefits

  • Scratch-free finish

    Non-abrasive process preserves zinc thickness and appearance.

  • On-line cleaning

    Treat hot parts and fixtures without cool-down or water permits.

  • Lower rework

    Reduce hand touch-up and reject loops caused by coating damage.

  • Safer floors

    No water, slurry, or grit—cut slip and corrosion hazards.

  • Faster fixture care

    Restore hooks/jigs quickly to maintain uniform coating results.

  • Consistent throughput

    Short, predictable cycles maintain takt at the outfeed.

  • Fewer consumables

    Eliminate abrasives and solvent wipes; simplify disposal.

  • Easy to stage

    Portable units set up near kettle or packing with plant air.

From Inquiry to Production in 3 Steps

  1. 1

    1. On-line trial

    Set a small outfeed station and time ash removal on representative parts and fixtures.

  2. 2

    2. Process & ROI model

    Dial in nozzle/insert and airflow; estimate pellet use, labor delta, and coating rework avoided.

  3. 3

    3. Deploy at outfeed

    Stage a repeatable CO₂ clean before packing; extend to fixture maintenance by the kettle.

We cut scraping to near zero and stopped marking the coating. Parts move straight to packing, and fixture resets are way faster.
