In-place mold cleaning, without disassembly or cool down
A major problem faced by rubber molders is mold fouling. Build-up of cured material and mold release agents causes molds that stick, blemishes and unwanted flash on final parts, making them unusable and requiring line shutdown for cleaning. Traditional cleaning methods such as manual scraping or glass bead blasting can be time consuming, ineffective, damaging to molds and result in high labor and material costs.
Cold Jet dry ice cleaning allows for in-place cleaning – without major disassembly or cool down. And because dry ice cleaning systems use non-abrasive media in the form of recycled CO2, it won’t damage the molds. With dry ice cleaning, rubber molders can extend their running times and enhance their productivity.
Removing and reinstalling molds may lead to tool wear, as well as risk damage to the tool during out-of-press handling. The use of dry ice blasting eliminates many sources of mold and tool damage.
Tire manufacturers have seen benefits of using dry ice blasting technology in production costs reduced by approximately $1 million per facility annually, press downtime reduced by 65% due to in-press cleaning, annual production increase, elimination of need to hand drill micro vents, near zero-defect levels achieved, reduction in tool damage and a reduction in the need to re-stamp sidewall lettering.
