About Custom Manufacturing Services Inc

Custom Manufacturing Services, Inc. (CMS) and East River Metals, Inc. (ERM) operate from three facilities in Princeton, West Virginia, and Rocky Gap, Virginia. The business traces its roots to 1979 when Bob Graf founded East River Metals to produce metal enclosures for its sister company, American Mine Research. In 1995, Graf established Custom Manufacturing Services to combine ERM's sheet metal expertise with American Mine Research's electro-mechanical assembly capabilities. The two entities together provide precision sheet metal fabrication, turnkey electro-mechanical assembly, and powder and wet spray coating. Core processes include laser cutting, forming, welding, hardware insertion, and outsourced plating. The combined footprint spans more than 155,000 square feet of manufacturing, office, and warehouse space across the two states. Customers span mining, aerospace and defense, electronics, food processing, industrial machinery, and oil and gas. Named clients include American Mine Research, Moog, Pascor Atlantic, Forensic Computers, JBS, Caron, and Smyth Co. Machine. The company emphasizes complete in-house control over fabrication, assembly, and finishing to deliver quick turnarounds and consistent quality. Its quality policy targets exceeding customer expectations, supported by ISO 9001:2015 certification and statistical process controls such as CpK studies and FMEA.
