At MPS Plastics, all product design, tool and mold making, injection molding, assembly, and finishing are in-house processes. From start to finish, we closely monitor the progress of your project, ensuring problem-free production and on-time deliveries.

With twenty year’s experience solving even the most complicated design challenges, our engineering team consists of seasoned professionals. We welcome the opportunity to share our expertise and work closely with your designers…so close that you can consider us an extension of your own team. We believe such relationships foster trust and respect, both of which are essential to our business philosophy.

To produce great work, MPS Plastics engineers rely not only on their own experience and talent, but also on state-of-the art equipment and software. SOLIDWORKS, CADKEY, FASTCAD, Virtual Gibbs…all speed the design phase. And the faster your product is designed, the faster it is ready for production.
