4.Product feature and application
(1) Product feature
● Unmatched Accuracy
Our advanced 5-axis machining centers deliver high-level precision, even for oversized car door panel molds. This guarantees perfect fit of mounting holes, hinges, and edge seams—eliminating assembly issues and ensuring reliable performance in mass production.
● Smart Flow & Cooling Control
With tailor-made hot runner systems and 3D-printed conformal cooling channels, we ensure stable melt flow and efficient cooling. For reinforced PP+T20 materials, this means less warpage and shorter cycle times—boosting both quality and productivity.
● Premium Surface Finishes
Our ultra-fine polishing process allows molds to deliver flawless high-gloss or textured surfaces. The finished door panels meet the standards for direct application in premium automotive interiors, delivering enhanced aesthetics and durability while maintaining minimal defects.
● Durability That Lasts
We use certified high-grade steels such as 1.2344/1.2343,1.2738HH and 1.2738, combined with advanced heat treatment and nitriding. This ensures stable precision for over 0.5 million cycles and reduces maintenance needs, giving you a mold built for long-term performance.
