Dry Ice Blasting Applications:

Dry Ice Blasting Technology for Core Box Cleaning

Safely clean core boxes online, while reducing downtime, improving product quality and eliminating the risk of damage

Buildup of resin and sand on core box vents prevents core material from solidifying, and often causes vent clogging, which reduces product quality and creates scrap. Traditional cleaning methods are very slow, ineffective, can damage tooling and destroy vents on the core boxes.

Dry ice blasting equipment quickly and safely removes the buildup while the core boxes are online without creating secondary waste. The process is non-abrasive and will not damage screens, vents or the tooling. Cleaning core boxes with dry ice cleaning leads to a significant reduction in production downtime and scrap rates.

We estimated that it would pay for itself in six months, but it took only one month. This machine is incredible. Every foundry needs to own a dry ice cleaning system!
