High-cavitation injection molds require near-perfect surface replication. For a German automotive lighting supplier, JUPAICNC’s 5-axis machines with 0.1µm resolution produced polycarbonate lens molds with 0.02µm Ra finishes. The Smart Thermal Control system maintained bed temperature within ±0.5°C during 72-hour continuous runs, preventing stress-induced birefringence in final products. Post-mold measurements showed 99.2% of 2.8 million lenses met optical clarity specs.
JUPAI’s trochoidal milling strategies reduced roughing time by 41% on hardened tool steel (HRC 62). By optimizing tool engagement angles in real-time, we extended end mill life 3.8x while maintaining 4µm profile accuracy. The client reduced mold development cycles from 14 weeks to 8 weeks – their fastest project turnaround in 30 years.
