For More Information: Cold Jet LLC / 513-716-6330/513-382-1168 / FIGURE 5: This automation cell includes a dry ice deburring system. It also improves worker safety by eliminating their exposure to such chemicals. By eliminating secondary waste streams, it also supports the zero-landfll initia- tives of many companies. Dry ice cleaning is approved by the U.S. Food and Drug Administration, U.S. Environmental Protection Agency and U.S. Department of Agriculture. Extended mold life. Dry ice cleaning extends the asset life of a mold because it does not wear away critical mold tolerances such as parting lines, shutoffs, roll-over edges, etc. Faster cleaning. Mold clean- ing with micro-particle dry ice is typically four to six times faster than traditional cleaning meth- ods. It increases plant capacity by minimizing downtime, and because molds can be cleaned in the machine, it extends produc- tion runs. Additional Uses In addition to mold cleaning, micro-particle dry ice systems are also often used to deburr and defash plastic parts (see Figure 4). Many such deburring/defash- ing systems are automated in-line with blast nozzles mounted onto sub-spindles or off-line in automation cells. Dry ice systems also can be integrated into such production solutions with the blast on/off signals controlled by the automation cell, and the dry ice level and sys- tem ready signals provided by the blast unit (see Figure 5). Mold cleaning is critical to the production of quality products, and micro-particle dry ice cleaning systems can be effective maintenance and production solutions that enable proces- sors and mold maintenance personnel to do more with less time and fewer resources.
