The iron sand castings they were using had porosity, so Dura-Bar was a natural alternative due to no sand in the process. Because the impeller is made in multiple lengths, a custom near-net shape from Dura-Bar meant no more pattern costs or long lead times. Superior machinability was an additional benefit, with faster cy cle times and ultimately significant cost sa vings. The conversion to Dura-Bar made a dramatic difference for this customer, with improvement in cost, consistent quality, ma
