No doubt about it, injection molding is MPS Plastics’ forte. Our experience with virtually all thermoplastics, ranging from commodity grades up to exotic, high-performance, engineering grades renders projects other companies might find difficult practically routine for us. Also, this experience with diverse plastics, from ABS to Zytel, matches our experience with diverse industries, as we have served the automotive, biomedical, telecommunications, and consumer industries…among others. If you are interested, we will gladly provide references.

At MPS Plastics, our array of equipment includes machines ranging from 28 tons to 400 tons, and can handle shot sizes as small as 0.10 ounces and as large as 32 ounces. That represents a lot of flexibility with regard to part size.

Finally, once your product is ready for production, we’ll do short, medium, or long runs…whatever it takes…to help you get your product to market. And that includes finishing and assembly.
