You’ve finished the prototyping phase. Your design is locked, the stakeholders are happy, and the market is waiting. But here’s the rub: you aren’t quite ready to pull the trigger on a $50,000 steel mold for 100,000 units. You need parts now: maybe 500, maybe 5,000: to bridge the gap between your R&D lab and the full-scale factory floor.

Welcome to the world of bridge production.
