Rapid Tooling, Serious Endurance
Bridge tooling is your accelerator, not a compromise. Manufactured from aluminum or soft steel, it’s the strategic shortcut that eliminates the gap between 3d printing and mass manufacturing.
It empowers you to validate market demand with genuine, production-grade parts today, all while retaining the flexibility to fine-tune your design without committing to the huge cost of full serial molds. Go to market faster, smarter, and cheaper.
Our bridge tools give you the ultimate competitive edge: the speed of a prototype with the endurance of a production mold. We can have your custom tool ready under 5 weeks, yet our rigorous engineering ensures it’s built for the long haul—capable of running up to 40,000 high-quality shots.
