A customer that we have proudly produced parts for since the late 1980s recently (2022) approached us about a crankcase for one of their industrial air compressors. It houses the crankshaft, crank, and connecting rods all while reducing vibration. This 49.5 lb class 30 gray iron crankcase takes a 44 lb isocure core which is placed into a mold made on a Hunter 20 (20x24). Warsaw foundry produces shell and oil cores inhouse, and we outsource isocure cores to a local supplier. Final inspection includes a brinell hardness test and visual inspection.
