A Special Message from RJG, Inc.


The later in the process issues are addressed, the more expensive and less effective the project.

TZERO: Do you have a strategy for your injection molding simulation?

Would reducing time to market and waste eliminate headaches for you and your supply chain?

RJG’s TZERO™ program helps world-class companies cut the cost and time wasted on adjustments during a tool launch. Our unique TZERO approach provides a framework for collaboration between engineering and manufacturing in review of part design and simulating, educating, optimizing, and assessing the mold development process to avoid molding uncertainties.

Making changes down the line in the tool launch process is time-consuming and expensive. Our tools allow you to catch any necessary adjustments early, launch the tool using a documented scientific plan, and rely on more than just hope when launching the mold for the first time.

Our competitive advantage is our injection molding knowledge coupled with our global scale and depth of language proficiencies, allowing us to support you across the globe.
