Our own tool shop

Molds built in our own tool shop

We build new injection molds on U.S.-made mold bases in our company-owned tool shop and run them on our own presses in Tennessee and Ohio, so the people who build your mold work with the people who mold your parts. The same shop evaluates and repairs transferred molds and keeps every tool in shape with preventive maintenance and dry-ice cleaning.

We prioritize U.S.-made components: every mold starts on a U.S.-made mold base, and we choose American-made components wherever they are available.
