Carl M. Cummings Manufacturing Co (CMC) is a subsidiary of Maven Engineering Corporation, originally a division of TRW. With a history dating back to the 1920s, CMC specializes in the manufacturing of valves using a unique flash welding process that reduces the risk of cracking or breaking, setting their valves apart from competitors. Their computer-controlled flash welder ensures precise control over the heating and forging phases, while the use of Fiber Optics guarantees optimum quality in the manufacturing process. CMC's valves are known for their superior grain flow, providing exceptional strength and reliability, and are used in locomotive, marine, and industrial engines worldwide.
As part of their commitment to quality, CMC stamps all of their valves with identification on the stem, enabling traceability of material and certifications. With a focus on reliability and longevity, CMC's valves undergo a forging process that refines the grain structure and enhances the physical properties of the metal, including strength, ductility, and toughness. Operating under an ISO 9001 2008 Quality Management System, CMC ensures that each valve meets rigorous standards through thorough inspections and documentation. With a dedication to excellence, CMC continues to be a trusted manufacturer of valves for various industries.
