Southeast Michigan-based Tri-Way Mold & Engineering is an expert in creating both prototype and production plastic injection molds. Tri-Way started off making tiny, precise injection molds in 1976; in 1995, we moved into larger molds, mold repairs, and mold engineering modifications.

We relocated to our current location in Roseville, Michigan, where we now employ a large number of skilled plastic injection mold experts, in 2000. For more than 45 years, we have kept on offering our clients top-notch service and blazingly quick response.
