Prototype Cast Iron Castings
Prototype Cast Iron Castings are a key part of our low-volume and prototype casting services at CPM Industries. We specialize in managing gray iron casting projects from start to finish — including pattern tooling, casting, machining, and testing — with full process control and flexibility.
With an in-house pattern shop and machine shop, we can respond quickly to changes, minimize costs, and reduce lead times. Our foundry network supports a wide range of part sizes and complexities, giving you access to the right casting partner for each project.
Whether you need a single casting or a short run, CPM provides complete turnkey support for prototype gray iron castings — including secondary processes like heat treat, inspection, painting, and coating.
