Our Facilities

Gateway Plastics, Inc. specializes in plastic injection molding for major corporations across North America. Since our start in 1970, we’ve grown consistently over the years and now occupy a state‑of‑the‑art 280,000 sq. ft. facility in metropolitan Milwaukee.

Our expertise includes in‑house design of custom plastic product solutions as well as in‑house tooling, mold construction and all secondary operations from assembly to warehousing and distribution. We are recognized for our high quality products, competitive prices and on‑time delivery.

We take great pride in our facilities, our people and our commitment to quality — which includes official certification to the ISO 22000:2005 Standard for food safety and FDA compliance. In fact, while inspecting our facility, a global manufacturer commented that our entire operation was cleaner than most clean rooms.
