Molding processes
We match tooling and process to your part and quantity, from a handful of samples to small production runs.
Injection molding
Insert molding
Threaded inserts molded in
Brass nuts and metal parts go into the mold, so no post-assembly is needed
Overmolding
Soft-touch grips and two-color looks
A TPU / TPE layer over a rigid part for grip, damping or a second color
Pilot runs
Pre-launch batches and validation
Small batches after first-article approval to validate assembly and market response
Why injection molding prototypes
Invest in a mold once and every part after that is consistent in size and finish.
-
01
Highly consistent
Parts from the same mold match in dimensions and appearance, ideal for repeated assembly and testing.
-
02
Low unit cost
Once tooling is spread across the run, unit price drops with quantity, beating 3D printing and CNC at volume.
-
03
Production materials
The same resin grades as mass production, so test results reflect the final product.
-
04
Complex features
Snap fits, ribs and bosses are molded in one go, and inserts or overmolding cut assembly steps.
Where it fits
-
Pre-launch pilot runs
A first batch after design freeze for certification, channel samples and market testing.
-
Functional and assembly testing
Parts that need production materials to check strength, heat resistance and fit.
-
Parts with inserts or soft touch
Handles, buttons and housings with threaded holes that need inserts or overmolding.

What are injection molding prototypes?
Injection molding forces molten plastic into a mold cavity, where it cools into a part. It is the most common way to mass-produce plastic parts. Prototype molding usually uses aluminum or soft steel tools, which cost less and are faster to make than production molds, so you can build a batch before committing to production tooling.
For a few cosmetic or fit-check parts, 3D printing or CNC is usually faster and cheaper. Once you need dozens of parts or more, production materials, or production-grade consistency, prototype molding is the better fit. Before tooling we run a manufacturability review covering draft angles, wall thickness and undercuts to reduce mold changes.
