| Factory Advantage | Tackling the dimensional instability of hygroscopic PA66 is where we excel, especially for critical AI server components. The material's high, non-uniform shrinkage often forces others into secondary operations, compromising tolerance stack-up for blind-mate connectors. We bypass this entirely by leveraging the superior platen rigidity and thermal stability of our Chen Hsong JM Mark 6 208T machines. The robust clamping system prevents mold breathing and flash, even with PA66's low viscosity. More critically, precise thermal control across the cycle minimizes differential shrinkage, allowing us at MechanoFab to mold net-shape parts like fan shrouds and connector blocks that meet UL 62368-1 requirements. This single-shot approach eliminates post-processing variables, directly mitigating chassis resonance and ensuring consistent alignment. |
