were discovered on the impellers. T e order was relatively small, but


Tech Cast’s ability to produce the cast- ings quickly and cost eff ectively has resulted in additional opportunities with SPX. While Tech Cast plans to continue


to receive its 3-D molds from an outside vendor, additive manufactur- ing can reduce tooling costs and lead times, which can make investment casting more competitive by reducing lead times for short-run components. “Traditional investment cast


tooling can take 8-12 weeks to build and may require signifi - cant capital investment, both of which can present barriers to entry into this manufacturing process,” McKinney said. “T e use of additive manufacturing technology to produce quality investment castings represents an area of organic growth opportunities for investment casting manufacturers to expand their businesses.”


SPX’s BB2 is a horizontal, single-stage pump used in a variety of heavy duty applications.
