Overview

Engineering that simplifies your part and your costs

Plastic part design is our specialty — we can take your idea from thought to finished part in a short amount of time. We work through design details to simplify your product and always design with the end use and assembly in mind, lowering your labor costs.

Our Engineering Workflow

From concept review to a production-ready, prototyped design.

1

Design & DFM

We refine your concept for manufacturability — wall thickness, draft, gates, and assembly — to make the part simpler, stronger, and cheaper to produce.

2

Prototype

Our Design Center pairs CAD workstations with five in-house 3D printers (FDM and SLA), so designs go from screen to testable part without leaving the building.

3

Tool & Produce

We have the production mold built by trusted partners to our design, then our presses turn the approved design into finished parts.

Why Pioneer

In-house expertise that turns investment into profit

Pioneer's expert team can turn your initial investment into substantial profit with an expertly crafted prototype and final manufactured product — educating you on the options at every step.

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.

Part & mold design

Decades of design experience to create the best version of your product and the tool to make it.

Tool & die shop

Collins Engineering repairs, modifies, and maintains tools in-house; new molds are built by trusted partners to our spec.

Design Center

A dedicated space with CAD workstations and five 3D printers — validate fit, form, and function before investing in tooling.

Guidance at every step

We educate you on the molding process so you know exactly what to expect.

Already have a design — or just a sketch?

Either way, send it over. Our engineers can take a finished CAD model, a rough napkin sketch, or anything in between and turn it into a manufacturable, production-ready part. Early DFM input saves the most time and money.

★★★★★

"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."

Engineering Services FAQs

Can you design my part from just an idea?+
Yes. Plastic part design is our specialty — we can take your idea from a thought to a finished part in a very short amount of time, handling design, prototyping, tooling, and production.
What is design for manufacturability (DFM)?+
DFM means engineering the part so it molds reliably and economically — optimizing wall thickness, draft, gating, and assembly. We always design with the end use and assembly in mind to lower your costs.
Do you build the tooling for the parts you design?+
We manage it end to end. We design the tool and have it built by trusted partners to our spec; our in-house Collins Engineering shop then repairs, modifies, and maintains it, keeping design and tooling tightly coordinated.
Can you prototype before we commit to a mold?+
Yes. Our Design Center has five in-house 3D printers (four FDM, one SLA) beside our CAD workstations, so you can test and refine the design — even run initial production — before investing in a production tool.
What does design for manufacturability look like in practice?+
DFM is the discipline of designing a part so it can be molded reliably, repeatably, and economically. In practice this means keeping wall sections uniform so the part cools evenly, adding draft so it ejects without drag marks, positioning gates where flow will fill the cavity completely without knit lines in visible or load-bearing areas, ribbing thin walls for stiffness rather than thickening them, and planning parting lines where they will not interfere with function or appearance.
What design problems do you catch early?+
Thick bosses that create sink marks on the opposite surface. Sharp internal corners that concentrate stress and crack in service. Zero-draft vertical walls that scuff on ejection. Undercuts that quietly double tooling cost by requiring a slide. Text or logos placed where they cannot be machined cleanly. Every one of these is inexpensive to fix in CAD and expensive to fix in hardened steel — which is why early engagement saves the most money.
Should I prototype before committing to a production tool?+
A production mold is a significant investment, and the worst time to discover a fit problem is after the steel is cut. In-house 3D printing lets you hold the part, test assembly with mating components, check ergonomics, and validate critical dimensions in days rather than weeks. Several inexpensive iterations at this stage routinely prevent a costly tooling revision later.
What happens between approved design and production?+
Once the design is signed off, the mold is built to our design by a trusted tooling partner, we run first articles for your inspection and approval, and the part moves into scheduled production. Because design, tooling, and molding all live under one roof, feedback loops that normally take weeks between separate vendors happen in hours.
