Dry ice blasting for injection molds
Resin build-up, mold release residue, carbon deposits: dry ice blasting cleans your injection molds in place, between cycles, without disassembly or solvent. Zero scratching, immediate return to production.
A dirty mold costs you money
- Resin and release agent build-up degrades part quality and finish over cycles
- Manual cleaning requires full disassembly: hours of downtime per intervention
- Solvents and abrasive brushes risk scratching polished cavities
- Carbon deposits accumulate in vents, causing gassing defects
- Waiting too long between cleanings shortens mold lifespan
Clean mold, back in production fast
- Cleaning in place, on the press, between two production cycles
- No disassembly, no solvent, no abrasive contact with polished surfaces
- Removes resin, release agent and carbon deposits from vents and fine details
- Zero moisture, zero risk of corrosion on tool steel
- Mold ready to run immediately after the intervention
Mold types we clean
Plastic injection molds
Precision cleaning of cavities, cores and ejector systems for thermoplastic injection.
Rubber & elastomer molds
Removal of vulcanisation residue and mold release build-up on rubber compression and injection molds.
Die-casting molds
Cleaning of aluminium and zinc die-casting tools, removal of metal deposits and release agent.
Blow molding tools
Cleaning of cavities and pinch-off areas for bottle and container blow molding.
Composite & RTM molds
Gentle cleaning of composite tooling surfaces without damaging gel coat or fine texturing.
The advantages for your production
Preserves polished surfaces
Non-abrasive process, no risk of scratching or altering dimensions, even on high-gloss polished cavities.
Cleaning in place
Performed directly on the press, between two cycles, with no need to remove the mold from the machine.
Access to vents & fine detail
Reaches narrow vents, undercuts and fine texturing that manual cleaning cannot properly access.
Extends mold lifespan
Regular non-abrasive cleaning reduces wear compared to manual scraping or aggressive solvents.
How often should molds be cleaned?
High-cadence molds
Weekly to bi-weekly cleaning for molds running continuously in multi-shift production.
Standard production
Monthly cleaning for molds in regular, single-shift production runs.
Between material changes
Systematic cleaning when switching resin colour or compound to avoid cross-contamination.
Before long storage
Full cleaning before a mold is stored, to prevent corrosion and residue hardening over time.
