Injection Molding, From First Shot to Full Production
We manage tooling from design to delivery. No minimum runs.
What We Handle
Design Review
Before any steel is cut, we review your part for moldability: wall thickness, draft angles, gate and parting line locations, and features that can cause sink or warp. Catching these early saves tool changes later.
Tooling
We build tooling in the U.S. or overseas, matched to your part, volume, and budget. Molds are designed in 3D first, so you can see how the tool works before it is built. The tool is yours.
Molding
Short runs to full production, with no minimum run. We match the process and the material to what your part needs to do.

Quality
Parts are inspected before they ship, checked against your drawing and the dimensions that matter most.
Stocked Inventory
We can hold finished parts and ship them as you need them, so you are not waiting on a new run every time you reorder.
Molding Processes
Injection Molding
Molten plastic is injected into a closed steel or aluminum mold. Best for solid parts like housings, covers, brackets, clips, and caps.
Blow Molding
A tube of hot plastic is captured in a mold and inflated with air. Used for hollow parts like bottles, tanks, and containers.
Injection Stretch Blow Molding
A preform is injection molded, then stretched and blown into its final shape. This is how clear, strong bottles like the ones shown here are made.
Rotational Molding
Plastic powder is heated in a rotating mold so it coats the walls evenly. Used for large hollow parts like tanks, bins, and housings.

Common Questions
Do you do injection molding in Kansas City?
Yes. We're based in St. Joseph, Missouri, about an hour north of Kansas City, and work with Kansas City-area companies from prototype to production, with no minimum run.
Is there a minimum run?
No. Buy the tool and run one part, or run thousands. It doesn't matter to us.
Who owns the mold?
You do. The tool is built for your part.
What materials can you mold?
Most common plastics and many specialty resins. Tell us what your part needs to do, and we'll help choose the correct solution.
How long does tooling take?
Typically 4–12 weeks, depending on the complexity of the project.
Do you build tools in the U.S. or overseas?
Both. We choose based on cost, timeline, volume, and quality.
What does tooling cost?
It depends on part size, complexity, and volume. Send us your part and we'll quote it.
Do you also do rotomolding?
Yes. For large, hollow parts like tanks, bodies, and housings, rotomolding is often a better fit than injection molding, with lower tooling cost. We'll recommend the right process for your part.
