We recently received an order to make tooling for this impeller, but our customer only had a drawing.  We made a 3D Cad model using SolidWorks2016 and generated toolpaths for our CNC.

Once the pattern and core box were cut we rigged them to run at the foundry.  The core box needed vents because that core was blown.

At the foundry they made a sand mold of each half of the pattern and the cores were made and set in the mold to form the interior passages of the casting.

Once the molds are closed the castings are poured, after cooling they are shook out, ground, and shot blasted to give it a nice surface finish.  Our total timeline on this part was less than 2 weeks from receipt of the drawing to finished casting.  The foundry only made one so we can provide a dimensional report to their customer for approval before running the balance of the order.
