We Design It

With over 35 years of plastic molding part design & mold design experience, Pioneer has the background, expertise, and determination to create the best version of your product and build the mold to produce it.


We Build It

Our skilled tool and die craftsmen use lathes, mills, or CNC machining to build the mold at our in-house tooling shop, Collins Engineering, Inc. In-house plastic machining & tooling saves you time and money with quick design modifications and a mold guarantee.


We Mold It

We take that mold and use plastic injection to produce your plastic products. In the molding process, injection molding machines force liquid resin into the mold cavity to form the part. Pioneer currently operates 22 modern plastic injection molding machines ranging from 75-ton to 880-ton clamp force.


We Inspect It

Pioneer utilizes a rigorous quality control system when testing plastic products for defects or imperfections. Only the highest quality plastic molded parts will be packaged after the quality control testing process.​ All molds at Pioneer Plastics are on a preventative maintenance schedule between production runs, so your mold always stays in excellent condition.


We Ship It

With a geographically centrally-located headquarters, we ship your finalized plastic products directly to your consumers and retail partners. Our 50,000+ square foot production and distribution facility is located in the heart of the Midwest, just a few hours from Indianapolis, St. Louis, Louisville, and Nashville. We have excellent access to all major transportation networks, allowing us to ship your custom plastic parts efficiently.
