JMC Rollmasters - Dennis Johnston

Dennis Johnston

President/CEO

Dennis began his career as a second generation roll maker in 1961 as a shop laborer at the original ARDCOR Div. of the American Roller Die Corp. Under the mentoring eye of his father Merle L. Johnston he quickly learned the roll making process. His leadership ability, mechanical and mathematical expertise led to rapid advancement within the organization. From laborer to machinist to roll turner (it was manual in those days) to expeditor, to roll shop superintendent. By 1965 with Merle as plant manager and Dennis as shop supt., the Johnstons were running the Ardcor manufacturing facilities. Dennis’ problem solving abilities also meant he was called upon frequently for troubleshooting customers problems in the field.

 

The challenges and rewards of the business environment coupled with an independent spirit inevitably led to the founding in 1967 of Johnston Mfg. Co, Inc. with Merle and Dennis as partners. Their goal was to produce and service tooling for the welded tube and pipe industries. When engineering and manufacturing technology evolved into the digital age Dennis was quick to embrace this new science. He soon began to integrate his skills of roll design and manufacturing into computer software. The goal being to digitize what he believed was an undocumented design and manufacturing process.

 

Through the use of software and CNC equipment tasks that would take hours to perform could be done with a mere mouse click. And, best of all, with no mistakes. All that was needed was database development, CAD source integration, APT language programming for CNC output, bar coding for error free data transfer and networking of all the above. Rather than acquiring generic software products he developed his own. This development is ongoing and renders JMC Rollmasters unimpeded by the limitations of generic or third party software and systems.
