Structural Aluminum Becomes the Next Robotics Scaling Hurdle

While artificial intelligence dominates robotics headlines, the physical reality of scaling from a few hundred units to tens of thousands rests on structural hardware. According to the International Federation of Robotics, annual installations are projected to climb from 603,000 in 2025 to 806,000 by 2029, putting immense pressure on supply chains. MES Inc. founder Hiten Shah notes that teams often attempt to maintain prototype designs as they move toward mass manufacturing, only to face costly redesigns and schedule delays once tooling is already committed.

To avoid these pitfalls, engineers must shift their strategy before locking in designs. Billet machining, while effective for early-stage development, frequently fails to translate to the die casting, extrusion, or forging processes required for volume efficiency. Engineering Manager Brad Layne emphasizes that components such as harmonic drive casings and structural frame members require distinct metallurgical and process approaches. By conducting design-for-manufacturability reviews and qualifying suppliers early, manufacturers can bypass the risk of losing entire tooling cycles during the critical transition to full-scale production.
