Not your run-of-the-mill training course

There is a reason Master Molder® is listed as a requirement in job descriptions across the globe. We offer an outstanding, participant-centered learning experience that provides solid skills you can apply immediately at your facility. We’ve worked with experts in the training field to design a program that provides the perfect balance of lecture and activity-driven teaching to maximize knowledge retention.

In this class, you’ll learn to apply advanced methods, strategies, and techniques of injection molding from the plastic’s point of view. This training is taught in a real-world production floor environment and is so effective that it won the Pike’s Peak Award.

Why RJG Training Courses

Award Winning

RJG’s training is so effective that it won the Pike’s Peak Award.

Real-World Experience

Participants are able to solve real-world problems to connect what they learn in the classroom to the plant floor.


Learning doesn’t just take place in a lecture hall—it happens through doing and practicing on machines in our fully-loaded, world-class facilities.

Experienced Trainers

Our trainers are just like you—they’ve been plant managers, molders, and engineers, so they understand what issues you face on a day-to-day basis and how to solve them.


Interested in implementing DECOUPLED MOLDING® strategies after taking this course? We can help.


Each class is built around its participants—it focuses on student interaction and problem-solving to greatly increase understanding and knowledge retention.


What Our Past Students Say…

We are now able to make more than twice as many parts in the same amount of time—one process part output increased from 16,000 to 40,000 parts per day. Our scrap rates have also decreased significantly since implementation. We now have a more robust injection molding process that is less sensitive to resin lot to lot variability thanks to Decoupled II molding.

Christopher Weaver, Project Engineer at MEDRON LLC

We chose RJG’s training courses because they are well recognized and respected in the industry, and they complement our internal training very well. RJG training goes into greater depth than most, it’s challenging, and you get a sense of accomplishment when you complete a course. Our two companies working together sets us up for success.”

Eric Pipkin, Technical Operations Manager at New Berlin Plastics

RJG’s method of training made a huge impact on our company and will continue to make a difference in the industry as a whole.

Jose Bando Huerta, Mechanical Process and Molding Engineer at Robert Bosch Sistemas Automotrices SA de CV

RJG training is unlike any other injection molding training available today, and I believe the results we have seen speak for themselves. We’ve been able to eliminate ongoing quality issues that we weren’t able to resolve prior to working with RJG, and we plan on continuing to work with them in the future.
