AscoJet presented its Dry Ice Blasting system, a non-abrasive method of cleaning molds. This method uses compressed air to accelerate dry ice pellets onto the molds at a speed of up to 300 m/second. After impact, the dry ice pellets immediately go back into the atmosphere, leaving behind a clean, dry surface.

The new Delta-Phase Shakeout presented at GIFA by Carrier Vibrating Equipment Inc. is designed to easily adjust to product change, almost eliminating sand carryover and casting damage. The patented Delta-Phase Shakeout uses a variable angle of attack to adjust effectively to each new casting that it encounters. It also can increase output and quality by maximizing sand removal while decreasing maintenance costs and downtime.

Didion International featured its New Mark 5 Series Rotary Media Drum which performs shakeout, sand conditioning, double sand screening, casting cleaning, and casting cooling in one efficient step, so the facility stays much cleaner with less airborne silica dust. By combining these processes metalcasters can save $40-$80/ton. The patented design has the lowest operating cost per ton in the industry worldwide.

The Mark 5 Series streamlines production by delivering cool and clean castings directly to the finishing department. The return sand is blended and conditioned so it is consistent in temperature and moisture content providing better control at a mixer. The sand stays in the system where it belongs. Dust collection is extremely efficient due to the small open area of the dram, and it requires 75% less dust collection than a vibrating shakeout rated at the same capacity. Counterflow air eliminates fugitive dust from escaping, protecting workers from airborne silica dust.

Other system improvements include water quenching directly following the machine to eliminate long cooling conveyors further saving equipment costs, energy, time, and space. For foundries using casting baskets and stage cooling, water quenching following the Rotary Media Drum can streamline production flow and eliminate the bottleneck in the cleaning room.

On display at the General Kinematics booth was the firm's Two-Mass, High-Frequency Vibratory Shakeout and its Vario-Drive shakeout system that was schedule for delivery to Sibelektromotor in Tomsk, Russia. The vibratory shakeout boosts casting throughput by compensating for varying load conditions, assuring full, non-dampening performance. These systems can handle up to 100,000 lbs. and are driven with sealed vibratory motors, eliminating the need for v-belts, pivoted motor bases, couplings and large bearings. The Vario-Drive shakeout system (which is not available in the U.S. or Canada) allows users to adjust casting retention time with the push of a button. In addition, the systems long-lasting components and heavy-duty construction offer extended uptime and low maintenance operation.

Also on display were three new models in the Ducta-Series of rotary drums--Ducta-Sprue, a sprue mill, Ducta-Screen, a rotary shakeout, and Ducta-Clean, a rotary media drum. Ducta-Sprue removes sand from sprees and gates, then collects and conveys it away for recycling while crushing mold and core lumps for higher reclamation rates. Ducta-Screen processes molds to separate and remove sand from castings. Sand exits the drum onto a vibratory conveyor, removing hot sand from the rotating body. Ducta-Clean offers cleaner castings and reduced maintenance by rubbing castings with media to remove tramp sand while separating sprue and gates from castings.

The IceTech Combi presented at GIFA combines dry ice pellet production and dry ice blasting.
