Injection Molding Tool Options for Plastic Parts
Choose from two molding options tailored to your manufacturing needs
We make it easy for you to work with us from prototyping through production. Using scientific molding techniques, we optimize your parts for production and monitor them in real-time via our machine connectivity network, saving you time and simplifying process qualification across your development stages. Every step in our process is documented as a data point and that knowledge is applied to each run of your parts. Along the way, we offer DFM feedback and design consultation to improve part design, and in-process CMM inspection to verify critical dimensions and help you qualify parts and process quickly. Finishing options? We have a range of those, too, including Mold-Tech equivalent finishes.
Prototyping or On-demand Manufacturing Tooling?
While the molds themselves are similar, part quantities, lifetime maintenance, quality documentation, and pricing vary depending on which service option is chosen. The right one depends on your project needs.

Injection Mold Tooling Options
We have two options for injection mold tooling to meet your needs wherever you are in the product lifecycle. Our prototype molding process helps you cut product development cycles by weeks—sometimes months—and bridge to production with injection-molded parts within days. Our On-demand Manufacturing process is designed to meet your production needs, and helps you qualify parts quickly to seamlessly transition into production with scientific molding, in-process CMM inspections with GD&T, and a full suite of secondary operations to make sure that your parts show up and perform as expected.
| Prototyping | On-Demand Manufacturing | |
|---|---|---|
| Objective |

Why Use an On-demand Manufacturing Tool?
Start with advanced design for manufacturability feedback, which ensures that your design is optimized before a single part is molded. From there, our scientific molding process generates data and lessons learned and applies them to each run of your parts. Our in-process CMM inspection ensures and verifies dimensional consistency throughout the manufacturing process, and we finish with a 30 part capability study to verify your critical dimensions.
Our on-demand manufacturing service helps you simplify your supply chain so you can get quality parts easier and faster. We meet your inventory needs with no minimum order quantities, and offer supply chain flexibility ranging from bridge tooling and just-in-time (JIT) production to standard production and dual-sourcing strategies.

Enhanced Quality with Digital Inspections
Digital inspection reports on molded parts are available on every on-demand manufacturing order. Our metrology lab uses a 360-degree, 12-position 3D scanner that collects data, identifies dimensional variance, and creates a visual aid and color map for a direct CAD-to-scan comparison.
