Cast urethane parts are frequently used when color, surface quality, and toughness are required. Urethane molding is a perfect alternative for insert molding or over molding in low volumes with diverse material choices. Polyurethane casting can also be used for bridge-tooling between a 3D printed rapid prototype and an injection molding with a balance of quality, cost, and time. Urethane cast parts can also be clear, color-matched, painted (including EMI shielding), have installed inserts, and even custom finished.
