Mountains of Opportunity

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 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.

Over the years, CMS and ERM have succeeded because of three things: great employees, great products and great customers.  Our customers demand the best from us, so our quality policy is to meet and exceed their expectations so significantly that CMS and ERM become their overwhelming suppliers of choice.  We are confident that our employees, equipment, and ISO 9001:2008 certified processes can produce quality products, on time and at a competitive price in today’s marketplace.  We are also proud to offer our products and services from three modern facilities in West Virginia and Virginia comprising over 155,000 sq. ft. of office, manufacturing and warehouse space.  On behalf of our employees, thank you for your time and the opportunity to share our facilities and capabilities with you.  Please schedule a visit to let us show you what we mean by “Mountains of Opportunities.”
