Dry Ice Cleaning for Plastic and Styropor Injection
Dry ice cleaning is effective on the full range of substances found in injection production, including:
- Release agents
- Overspray
- Hardened plastic
- Burnt-on residue and a combination of all the materials used in the process
Clean in place, while the tool is still hot
One of the biggest advantages is that there is no need to remove the mould from the machine. Cleaning can be carried out in situ, and dry ice works even while the equipment is still hot — so there is no waiting for the tool to cool down and no reheating before the next run. What would normally take hours of dismantling, scrubbing and reassembly can now be done in minutes, and the line is back in production almost immediately.
Frequent cleaning has a double benefit: each cleaning cycle gets shorter, and reject rates drop to a minimum because the mould stays consistently clean. The result is a superior finish and higher part quality — achieved without dust, water or chemicals.
Why injection manufacturers choose dry ice
Mould preservation — the non-abrasive process protects the mould surface, extending tool life and lowering replacement costs. Dimensional stability — surface dimensions are maintained with no alteration to the tool. Lower reject rates — a 100% clean mould means fewer rejected parts and less scrap. On-site cleaning — work is done in place, minimising downtime and transport costs. Dust-free and dry — no blasting grit and no water residue or moisture on cleaned surfaces. Reaches the unseen — slots, screen vents and hidden cavities are cleaned thoroughly and simultaneously. Lower labour costs — faster cleaning means fewer hours spent on maintenance.
Dry ice cleaning is the ideal solution for maintaining plastic injection, rubber and aluminium moulds. Intelblast manufactures high-quality, reliable dry ice blasters at affordable prices — and supplies the fresh dry ice to go with them — so you can keep your tooling clean, your rejects low and your production running.
