Many foundries have solved the bottleneck problem in the cleaning and finishing departments by first updating their shakeout system. The amount of sand carryover as well as the sand adhering to the castings is the single biggest factor relating to shotblast costs (labor to operate, shot consumption, energy consumption, replacement wear parts, and maintenance time).

By reducing the sand from going into the casting cleaning department and helping it stay in the sand system where it belongs, the benefits go right to the bottom line. In addition to saving on all the above shotblast cost, other savings include less wear on the dust collectors, less waste streams, less airborne silica dust, and less clean up time.

When the castings are pre-cleaned in the shakeout system, the cleaning/finishing bottleneck is eliminated. Couple the pre-cleaning with casting cooling and the production flow is really streamlined.
