History of innovation
RJG has been responsible for many innovations in the plastics industry:
- Scientific Molding seminar
- Commercial strain gage cavity pressure sensors
- DECOUPLED MOLDINGSM techniques
- eDART System™ - the plastic industry's first digital data acquisition platform
- Master MolderSM and Tryout Shop Certification programs
Our business is helping molders supply absolute quality parts to their customers. We do this by providing process control systems, cavity pressure sensing technology, and processing training to the injection molding industry.
