JMC Rollmasters designs and manufactures custom tooling for welded tube and roll-forming mills, pairing its own roll-design software with CNC production and integrated manufacturing documentation. The company’s software tracks the neutral axis as metal moves through each forming pass, allowing strip-width recommendations and roll contours to be developed from dynamic forming data rather than generic formulas. Johnston Manufacturing’s tube-roll operations were later merged with Hartsgrove Machine in Rock Creek, Ohio, bringing JMC’s engineering systems together with HMI’s roll-manufacturing capabilities.
Precision Rollform TechnologiesFounded in 1951 by two Swedish craftsmen, Precision Rollform Technologies has spent more than six decades producing standard and custom metal parts through roll forming.
