Utilizing high-gloss paint-free materials and multi-station precision mold-rotating technology to achieve mirror-grade parting line control ≤0.05mm for automotive interior pillars. The two-shot composite molded parts (substrate thickness: 2-5mm) employ dynamic mold-temperature compensation and Mucell process to eliminate weld lines and flow marks, with surface hardness exceeding 2H. Ideal for luxury vehicle A/B/C pillar trims, passing 9H pencil hardness tests and -30°C~80℃ thermal cycling validation.
