| Factory Advantage | Effectively molding PEEK for surgical robotics hinges on mastering its narrow processing window and high melt temperature. The all-electric Zhafir Zeres III 60T is our solution; its servo drives deliver exceptional thermal stability and the shot-to-shot repeatability (<0.1% variation) needed to manage PEEK's high viscosity and prevent hydrolytic degradation. This precision allows us at MechanoFab to produce net-shape, complex components that meet micron-level tolerances and ISO 13485 standards directly from the tool. This single-step process is critical as it eliminates secondary machining operations, thereby avoiding the tolerance stack-up and contamination risks that plague less controlled manufacturing environments. The machine's oil-free operation is an added benefit for FDA-regulated production. |
