Custom Plastic Parts — From Concept to Finished Product

Let's turn your custom plastic part concept into reality. With 40+ years of part and mold design experience, Pioneer designs it, tools it, molds it, and ships it — all in-house.

Design & Tooling

We design your mold and have it built by trusted tooling partners; our own Collins Engineering shop then modifies and maintains it in-house for quick changes and long tool life.

Mold & Inspect

Presses from 75 to 1,200 ton force resin into the cavity; a rigorous QC system catches defects before anything is packaged.

Ship Anywhere

From the heart of the Midwest — hours from Indianapolis, St. Louis, Louisville, and Nashville — we ship efficiently to you or your retail partners.

Why manufacturers choose Pioneer for custom parts

We take pride in personal relationships — many customers have stayed 30+ years. We understand how hard customers are to earn and how important they are to keep, so we go above what is required.

All of it runs on an ISO 9001:2015 certified quality management system — documented processes, traceable materials, and controlled inspection on every run, not just the ones being watched.

Injection Molding vs. 3D Printing — which fits your part?

Before you request custom injection molding

Custom molding involves significant up-front tooling, typically $10,000–$250,000 based on size and complexity. If your project needs 1,000 units or fewer, alternative methods like 3D printing may be more cost-effective — just ask and we will guide you.

★★★★★

“We needed a custom, highly unique new device — but more importantly, a supplier partner that could be counted on to deliver an incredibly high impact project on an aggressive timeline. The supplier-partner submitted what was asked, but also took it a step further by providing a 2nd solution that cast their own unique design spin. This design set them apart from the group and, with their value-add on cost and timing, made it an easy decision on who to partner with. They say it’s easy to make things different but really hard to make them better. I can say today that this year’s supplier of the year winner helped make us better for many years to come.”
