CO2 blasting

Dry ice blasting is useful in such areas as coater cups, teos valves, ammonium nitride, etch parts, and implant parts. The CO2 EconoBlast model PT-110 (14 in. wide and weighing just over 100 pounds) employs rice-sized dry ice pellets that disappear on impact with the targeted surface. It is available with a variety of guns and has a storage capacity of 110 pounds. Alpheus Cleaning Technologies Corp., Rancho Cucamonga, CA; ph 800/445-6131.
