Your Satisfaction is Our Business

To ensure that we can exceed the expectations of our valued customers, we frequently update and invest in our foundry, ensuring that our processes, machinery, and procedures are as innovative as possible. We’ve built our reputation as a leading, New England-based nonferrous alloy casting foundry specializing in producing world-class metal alloy castings for a wide assortment of industries, including aerospace, automotive, biotech, electronics, firefighting, imaging, medical, military, packaging and statuary. Unlike most foundries, a large portion of our metal alloy castings contains multiple materials. We cast copper and aluminum around other materials such as cast iron cores and heaters. We’re always pushing the boundaries of what’s possible with alloy castings. As our list of capabilities expands, so does our client base.

Our foundrymen follow a strict set of documented procedures and efficient production methods. This enables us to guarantee our customers repeatable, consistent and affordable products. We also offer a variety of value-added services, including pattern design/production, heat treating, annealing, machining, powder coating, painting, anodizing and assembling for completely finished parts. In addition to these services, we also offer these unique capabilities which set us apart from other foundries:
