ERC Company was founded by Mike and Pat Coy in 1972. With over 40 years of experience ERC Company has become a recognized leader in the precision sheet metal and CNC machining industries of Southern California. ERC Company began as a manufacturer of dental ovens, sandblasters and dust collectors for dental laboratories. The company evolved into a job shop over the years due in part to the many original equipment manufacturers at trade shows seeing our dental equipment and asking us to manufacture parts for them.
