Custom Injection Molds, Tooling, and Asset Management

In addition to manufacturing the injection molded products, Polyfab LLC also builds the molds and tooling. Our total process management guarantees quality at every step of the injection molding process.

We work with an extensive tooling supplier partners, many of them within two hours of Sheboygan, to build customized molds. Then they are carefully tested to assure accuracy and consistency of manufacturing in accordance with each customer’s unique production part approval process (PPAP). It can typically take up to 24 weeks to build a new mold.
