Dry-Ice spray cleans molds fast. (Keeping up with Tooling).

Power DFX is a new dry-ice blast-cleaning system for molds that is available from Husky Injection Molding Systems Ltd., Bolton, Ont. Developed by Husky and CAE Alpheus, a maker of dry-ice blasting systems in Rancho Cucamonga, Calif., Power DFX reportedly cleans high-cavitation molds in 80% less time than manual methods and eliminates the use of hazardous solvents or disposable wipes. Mold components also do not need to be removed for cleaning. Husky's initial market is PET pre-form tooling, but the system has wide application potential.

The portable system shaves dry-ice blocks, nuggets, or pellets into fine particles. Power DFX then draws the fine particles through small venturi nozzles into a stream of compressed air. The dry-ice spray vaporizes when it hits the mold surface, creating microscopic "explosions" of solid [CO.sub.2] into gas that "flushes away" mold residues, according to Husky sources. The system can clean out injection mold vents and hot-runner manifolds. It can also strip resin from plasticating screws and remove sticky residues from blow molds.

Power DFX uses only 25 cu ft/hr of compressed air and 0.80 lb/hr of dry ice, about one-third the amounts used by other dry-ice systems, according to Husky. It reportedly cleans hard-to-reach areas better than competing systems.
