In 1985, Rod Groleau started a training and consulting company (then named RJG Associates, Inc.), where he developed techniques for retrieving data for plastic conditions inside the mold, previous to this only data from the molding machine itself was used for processing techniques. By 1999, the company developed controls allowing for different "stages" of molding and the "DART" (Data Acquisition and Retrieval with Transducers) system, which allowed for data to be retrieved by personal computers. In 1998, the company began offering Master molder certifications, a training program of robust scientific techniques which is highly valuable to employers in the industry.[7][8][9][10] Since then, the company has continued to develop further innovations that have a major impact on the industry.[11][12]

We have an extensive in-house tool-room, equipped with the latest technology and staffed by experienced mould toolmakers. Our tool-room ensures optimum tool availability, on-time production to plan and high service levels for every customer.

RJG Inc. is a training, technology, and consulting company that specializes in the injection molding industry. They offer training courses around the globe, including Master Molder I and II, Systematic Molding, Injection Molding Essentials, and more.[1] They also offer CoPilot, a process control system that allows for data extraction of plastic conditions inside the mold using pressure sensors, transducers and strain gauges. The company is responsible for pioneering DECOUPLED MOLDING® techniques which have since become industry standard.[2][3][4][5][6]
