We are a global, full-service injection molding solutions company focused on improving quality in all aspects of life—from plastic parts to career advancement, reduced scrap in our landfills, improved safety standards, and more. We are passionate about what we do because we love it, and because we know that we are making a tangible difference in the world.
We have been transforming the industry since 1985, but our history reaches back much further than that. Our founder, Rod Groleau, developed the first in-mold cavity pressure sensor and the first computerized production monitoring system in 1962. He changed the industry forever, and we carry on his legacy through continuing to push the boundaries every single day.
To transform injection molding companies by delivering knowledge and data from the plastic’s point of view.
