    "factory_advantage": "Tackling the high, non-uniform shrinkage of PA66 is non-trivial, especially for components demanding tight tolerances like server chassis brackets. Its low melt viscosity often leads to flash on less capable machines. This is where our reliance on the Fanuc Roboshot α-SiB 50T provides a distinct edge. Its all-electric servo control delivers superior shot-to-shot repeatability, enabling us to precisely manage injection and packing pressures. This level of control at MechanoFab allows us to compensate for the material's shrinkage behavior directly in the mold, achieving net-shape parts compliant with EIA-310-D standards. This single-step process is crucial for eliminating the tolerance stack-up that causes blind-mate connector misalignment, a common failure point when secondary operations are required.",
