    "factory_advantage": "Processing PC/ABS blends for ground terminal radomes presents challenges with shrinkage and sink marks. Our approach leverages the Sumitomo SE-EV-A 450T's all-electric platform, providing the thermal stability and shot-to-shot repeatability needed to counteract the material's inherent 0.4-0.7% shrinkage and potential for warpage. The key advantage comes from Sumitomo's Z-Molding system, which allows for precise, responsive injection pressure control. This enables us to eliminate sink marks in thick-walled sections directly within the molding cycle, a common defect that often requires secondary fixes. At MechanoFab, we produce a net-shape, dimensionally stable component compliant with IP67 and UL746C standards in a single step, ensuring perfect antenna alignment without costly post-processing.",
