Plymouth Foundry, Inc. was asked by an Industrial Pump Company to provide impeller castings. Plymouth Foundry needed to be able to handle this project by producing impellers that were completely finished and ready to use. This can be time consuming and difficult without breaking off the vanes of the impellers, thus damaging them. The impellers needed to be poured out of gray and Ductile iron. The customer also needed a company that is both ISO 9001:2015 and PPAP Certified. Plymouth Foundry was able to take on the project without specific accommodations.

Plymouth Foundry was able to complete the service without damaging the newly poured impellers by hanging them on a tree that rotates while the steel shot cleaned the casting free of production debris. This process eliminated the need of tumbling the castings that would greatly increase the chances of damaging or breaking off the impeller vanes. This project allowed Plymouth Foundry, Inc. to think outside of the box. This created job specific routings on how a fragile casting is processed through the foundry. This allowed Plymouth to meet the customer’s quality impeller needs.
