    "factory_advantage": "Effectively molding complex polycarbonate optical lens mounts for XR devices hinges on defeating warpage and shrinkage. The extreme hygroscopic nature of this polymer demands absolute process stability, which is where we leverage the Engel duo 900T. Its superior thermal management and the shot-to-shot repeatability of the CC300 controller give us precise control over melt viscosity and packing pressure. This allows the MechanoFab team to achieve net-shape parts with complex geometries directly from the tool, meeting stringent CE and RoHS standards without secondary operations. By engineering away the need for subsequent machining, we completely avoid the associated risks of tool chatter, burrs, and the critical tolerance stack-up that compromises lesser manufacturing approaches. The result is a dimensionally perfect component, optimized for optical performance.",
