Versatile CNC Machined Gray and Ductile Iron Casting Solutions

Whether your custom castings require a rough cut, a qualifying cut or precision close-tolerance finished machining, our CNC machine shop is expertly tooled and staffed to handle the same size and geometry of the castings we produce in our foundry and pattern shop. When it comes to your custom CNC machined products and prototypes, our optimized production system translates into unbeatable turnaround times with uncompromised quality and consistency.
