We welcome you to browse our website and learn more about our company and the services we provide including: Metal Fabrication, Electro-Mechanical Assembly and Paint & Finishing. Our History at Custom Manufacturing Services, Inc. In 1979, Bob Graf founded East River Metals, Inc. to develop metal enclosures for its sister company, American Mine Research, Inc. At the time, AMR needed quick turnarounds on cosmetic and tight-tolerance enclosures. Building upon the experience of fabricating AMR’s products, ERM soon began fabricating parts for other companies interested in outsourcing their sheet metal work. In founding Custom Manufacturing Services, Inc. in 1995, we took the opportunity to combine the knowledge and experience of metal fabrication at ERM and electro-mechanical assembly at AMR. Today, both CMS and ERM offer state-of-the art precision sheet metal fabrication services, and CMS further offers turnkey electro-mechanical assembly services to a diverse group of successful customers in a wide range of industries.
