Design and Planning

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.

For a free, no obligation quote,

why not send us your CAD drawings via e-mail to rich@mpsplastics.com, or send a hard-copy blue print or file-on-disk?

Tooling

Some injection molders do just that…inject molds. Here at MPS Plastics, however, we manufacture your molds and all auxiliary tooling in-house. If you need to make a sudden change, no problem.

You have access to the expert toolmaker and engineer responsible for your project because everything is here at MPS Plastics.

Our fully equipped Tooling Center, which includes high-tech CNC milling equipment and EDM machines, offers you the utmost

in quality, precision, and flexibility. Once the computers, CNC and EDM machines have finished their work, MPS Plastics toolmakers then take over and apply the finishing touches, thoroughly checking

every detail.

MPS Plastics recognizes that not every project requires a complex, high-volume, and therefore expensive tool. That’s why we are willing to produce limited-life molds, mold inserts, and soft molds.

In fact, we encourage it if it’s best

for the project. Because it makes sense, and prevents you from squandering scarce financial resources. COST EFFECTIVENESS is an integral part of our business philosophy.

Finally, we are pioneering

a cost-saving technique we call

"time-share" molding.

Contact our Plant Manager at rich@mpsplastics.com to find out if this technology can help you save money.

Molding 

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 550 tons, and can handle shot sizes as small as 0.10 ounces and as large as 84 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.
