Our extensive experience with difficult casting jobs is what sets Warsaw Foundry Company above other casting providers. This is why this marine industry client contracted us to produce this complex casting. Designed for use as a water jacket header (riser) in a boat engine application, it required the assembly of complex cores and tight tolerances. This product required the use of our Hunter 10-C automated molding machine with a 14" x 19" flask and our Dependable 200 core machine. The molds were made from green sand and the water jacket header was cast from automotive gray cast iron per SAE G3000. After casting, the water jackets were shot blasting and ground per the customer supplied specifications. Weighing 19.73 lbs., we maintained the required tolerances to ±.030". Quality assurance was certified with final inspection, visual inspection, and Brinell hardness testing. Typical turnaround time was 4-5 weeks for cored assemblies; we currently produce 500 pieces 2 to 3 times a year for this client.
