Design. Mold. Assemble. Ship.
All under one contract.
We don't refer you out for tooling. We don't sub the assembly to a stranger. The
mold, the part, the secondary operations, and the box on the truck — one purchase
order, one source of responsibility.
Engineering-grade resins. Close-
tolerance work. Runs from
prototype to high volume.
Twenty-one presses ranging from 50 to 1,550 tons of clamp force, processing all the major commodity and engineering resins, on the same production floor.
We mold for thin-wall consumer parts, close-tolerance medical components, structural drone brackets, large industrial housings, and everything in between. Computer-controlled process monitoring runs on every press. Robotic part handling on the machines that need it. Operators with twenty- and thirty-year tenures on the ones that don't.
Standard capabilities
Production envelope
The shorthand version of what we can take on, today.
| Tonnage | 50 — 1,000 ton |
| Shot capacity | 2 — 75 oz |
| Part weight | 5 g — 10 lb |
| Volumes | 250 — 5,000,000+ |
| Resin families | 9 engineering grades |
Long mold life starts with the right
tool maker. We’ve spent decades
finding ours.
If you need a new mold, we'll oversee the build with one of the tool makers we've worked with for years — chosen for trouble-free, long-running tools, not the lowest line on a quote sheet. If you have an existing mold that's tired, damaged, or running short, we handle repair, refurbishment, and ongoing maintenance in-house or alongside our partners.
You'll never juggle three suppliers for one part. The mold lives on our floor, the parts come off our presses, and the responsibility starts and stops with us.
Tooling services
From sketch to first shot
Most new tools follow this rough timeline. Faster is possible; slower is rare.
Design review
Engineering reviews part geometry, gating, cooling, and ejection. 1–2 weeks.
Tool build
Build with vetted partner; weekly progress reports. 6–10 weeks typical.
First shot & qualify
Sampling on our floor; dimensional and process qualification.
Finished, packaged, and ready
to ship — without a second purchase
order.
The part coming off the press is rarely the finished good. We handle the in-between — welding, machining, sub-assembly, packaging, kitting — in-house or through carefully selected subcontractors. Either way, we take complete responsibility for the finished good.
If your line needs a tray of forty kitted units in a specific orientation, we'll deliver a tray of forty kitted units in that orientation. If you need cartons palletized to a customer specification, we'll palletize to that specification. If just-in-time delivery saves you warehouse space, we'll release weekly instead of quarterly.
