Molding and materials
Production runs across a range of press sizes, with insert molding and unscrewing molds available for parts that need more than a straight-pull cavity.
Ask about your partUpload your drawing. Someone who knows molding writes back today. A 3D-printed prototype can be in your hands tomorrow. Parts show up when you’re ready to assemble.
We take on the parts of the job that are easy to underquote and hard to deliver on: mold design, material behavior, and the discipline to run the same part the same way, shift after shift.

Ask about your partCustom molds and support tooling built for the production volume you actually need: parting-line and hot-runner molds, hydraulic core pulls, and side actions.
Talk tooling
We work from your CAD files, sketches, or an existing part, and 3D-print prototypes in house, as soon as the next day, so you can check fit and form. We help settle material, wall sections, and moldability before a mold is ever cut.
Start a design conversationSecondary operations to hand you a finished part, not just a molded one, so the piece that leaves our floor is the piece that goes on your line.
See what we finish in-houseMolding is only part of getting a product built. We handle the work after the press, so what reaches you is ready to use.
We assemble molded parts, and the components that go with them, into sub-assemblies. That means fewer part numbers for you to buy, receive and track.
Part numbers, logos, dates or serial numbers engraved permanently into the part, so it arrives identified and traceable.
We combine the parts you specify into one kit per assembly, counted and packed, so your line pulls a single package instead of several.
We bring parts to your door a few times a week, timed to when you are ready to assemble. No warehouse space, no waiting on a container.

Our tool room receives, inspects, repairs and qualifies molds built in China, Mexico or anywhere overseas, then runs your parts here in Connecticut.

A part that is right the first time is worth more than a part that is right eventually. Our process is built around catching drift before it reaches your dock.
Set parameters are monitored run to run, so the part you approved in the first article matches the part in run five hundred.
Resin handling, drying, and traceability practices built to keep material properties consistent across a production run.
Parts are checked against print at defined intervals during the run, on our own inspection bench, not just at the end of it.
We have been molding parts and building tools in Waterbury since 1987. We are close enough to bring your parts to your door ourselves, so we do.
