| Factory Advantage | Effectively molding this hygroscopic polycarbonate demands rigorous process control beyond just pre-drying. While others struggle with post-molding machining to achieve final geometry, risking tool deflection and tolerance stack-up, we eliminate these secondary operations entirely. At MechanoFab, we leverage the Arburg Allrounder A 2000T's superior thermal stability and its rigid, FEM-optimized clamping unit. This combination allows us to use the high injection pressures required for this material without platen deflection, achieving net-shape components in a single step. This is how we consistently deliver void-free, hermetically sealable LiDAR components and optically clear radomes with precise thickness, meeting stringent IATF 16949 and IP69K standards directly from the mold. |
