Our facility is fully equipped with 3- and 4-axis CNC machining equipment as well as manual machines to meet the general machining demands of various industries, including rail, truck, construction, pump, energy, mining, and prototype automotive. Plymouth Foundry specializes in machining custom components from castings as well as flat sheet or bar stock. Through machining, we add value to cast parts by facing, turning diameters, adding slots, pockets, holes, and complex surface contours. Gray iron and ductile iron sand castings, alloy steels, aluminum, stainless steel, and carbon steel are common materials that we machine. Special materials processed include plastic, nylon, and fiberglass reinforced plastic.

By utilizing our one-stop casting and custom machining services, OEMs and other industrial customers can reduce their overall product development cost significantly. Our machining capabilities include turning, milling, drilling, broaching, and grinding. CNC turning centers at our facility can machine parts up to 24" in diameter.

Our Brown & Sharpe CMM and DCC CMM systems enable us to verify part dimensions to your custom specifications. Plymouth Foundry’s division managers ensure smooth execution of your jobs from foundry to machine shop and keep you informed of the project status. Depending on your manufacturing needs, we also offer value-added services such as painting, assembly, and packaging.
