Why RJG® Training

Training is a vital step in ensuring your customers receive the highest quality parts. Without trained staff at your press, you can’t be sure that mistakes aren’t being made and bad parts aren’t being shipped. Investing in your team pays off time and time again.

We know plastic better than anyone else in the industry. Simple as that. We’re molders, process engineers, designers… experts.

RJG’s hands-on training allows you to practice as you learn, significantly increasing knowledge retention. Our participant-centered training is a unique approach that puts your needs first and adjusts to what you’re most interested in learning about.

Our goal as trainers is to give you real-world knowledge and tips that you can immediately put into practice when you get home.
