| Min Feature Size | Min Wall Thickness: ~1.0 mm; Min Hole Diameter: ~1.0 mm (highly dependent on material and depth-to-diameter ratio). |
| Precision Grade | Typically achieves part dimensional tolerances of ±0.10 mm to ±0.25 mm, conforming to ISO 2768-m. With a high-quality mold and a stable, optimized process, critical dimensions can be held within ±0.05 mm. Excellent shot-to-shot weight repeatability, typically <0.2%, is standard. |

| Factory Advantage | Molding optical-grade Polycarbonate 2405 for POCT devices presents a significant challenge due to its hygroscopic nature and the need to eliminate birefringence. Our approach hinges on the exceptional process stability of the Haitian Mars III 200T. Its servo-hydraulic system delivers precise, repeatable control over injection and holding pressures, which is critical for preventing the internal stresses and sink marks that plague laser-based diagnostics. While competitors may rely on secondary annealing to correct optical flaws, the MechanoFab process leverages the Mars III's robustness to achieve a net-shape, stress-free optical window in a single step. This strategy not only eliminates costly post-processing but also ensures consistent part-to-part quality, fully compliant with ISO 13485 standards for mission-critical medical components. |
