Established in Seattle by Mike and Bert Robins in 1986, SeaCast operates four full service investment casting foundries. In addition to casting, the facilities (Marysville WA, Seattle WA and East Greenwich RI) offer extensive support services such as CNC machining, heat treat and assembly. The company serves a wide variety of industries including: aerospace, industrial pumps, industrial gas turbines, medical, transportation and computer hardware. To meet rigorous customer requirements, SeaCast’s manufacturing processes have earned ISO9000, AS9100 and NADCAP certifications. Over 350 dedicated employees comprise SeaCast's workforce and the company remains privately held.

To broaden SeaCast’s wide alloy capabilities, the company has built a new titanium vacuum melting facility in Butte, MT. Production started in early 2011.
