    "factory_advantage": "Molding a hygroscopic ABS/PC blend for ground terminal radomes presents significant challenges with shrinkage and sink marks, which can compromise antenna alignment. Our approach centers on the Fanuc Roboshot α-SiB 220T's all-electric precision. The machine’s closed-loop servo control and exceptional shot-to-shot repeatability give us surgical control over injection pressure and temperature. This allows us to precisely manage the material's high melt viscosity and 0.4-0.7% shrinkage factor. By optimizing the packing phase with the machine's AI-driven process stability, MechanoFab produces thick-walled, dimensionally stable radomes that are free of sink marks and meet IP67 specifications as a net-shape part. This single-step process completely eliminates the risk and cost associated with secondary machining or rework that often plagues parts made on less capable, thermally unstable machines.",
