About RJG
RJG traces its roots to 1962, when founder Rod Groleau developed the first in-mold cavity pressure sensor and the industry's first computerized production monitoring system. He founded RJG Associates in 1985 as a consulting and training company, and in 1998 co-founded RJG Technologies to supply sensors and data acquisition systems. The two merged in 1999 to form RJG, Inc., and the company has since expanded internationally, opening RJG Germany in 2013 and acquiring G&A Moulding Technology in the UK in 2024.
The flagship product lines center on cavity pressure monitoring and process control. Lynx single-channel and embedded sensors use strain gage or piezoelectric technology, while multi-channel strain gage and piezo systems connect up to eight sensors to a single mold connection point. The CoPilot controller, including CoPilot Go and Heat & Cool Control, provides real-time process monitoring, and the eDART system was the plastics industry's first digital data acquisition platform with Lynx smart sensor technology. The Hub network server aggregates CoPilot data, and the Application Processor 4.0 handles processor-intensive tasks in harsh manufacturing environments.
RJG equipment serves injection molders across medical device manufacturing, packaging, automotive, consumer goods, and electronics. The company's technology is particularly valued in medical molding, where the CoPilot system has been validated for FDA-compliant processes with IQ/OQ/PQ testing. Molders in these sectors rely on RJG sensors and controllers to detect shorts, sinks, flash, and warp, and to maintain consistent part quality across high-cavitation molds.
On the used market, buyers seek RJG cavity pressure monitoring systems and CoPilot controllers because of their reputation for accuracy, durability, and long service life. The Lynx sensor platform and eDART systems remain widely supported, and used RJG equipment offers a cost-effective path to scientific molding practices. Parts availability and the company's extensive training ecosystem further support resale value, making pre-owned RJG systems a practical investment for molders upgrading process control.
