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.

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