Production details
1. Product feature and application
(1) Product feature
l Unmatched Accuracy
Our imported 5-axis machining equipment delivers micron-level precision for large-size Car Door Panel plastic Mold and Car Door Panel Automotive Mold. Every mounting hole, hinge position and edge seam of finished Automobile Plastic Part fits perfectly during assembly, sustaining consistent stable output throughout long-term Door Panel Molding and Door Panel Moldings.
l Smart Flow & Cooling Control
All Interior Automotive Mold and Car Interior Mold are fitted with exclusive hot runner systems and 3D printed conformal cooling channels. The design balances melt flow evenly when processing PP+T20 reinforced materials, shortens molding cycles and optimizes flatness of finished parts to raise your overall production capacity.
l Premium Surface Finishes
All Automotive Injection Moulds and Automotive Molds undergo ultra-fine mirror polishing. The Car Door Panel Mould consistently produces flawless glossy or textured surfaces that fully satisfy strict aesthetic standards for premium car interior parts, improving both appearance and durability of door panels.
l Durability That Lasts
Our Car Door Panel Automobile Mold adopts certified high-grade mold steel including 1.2344, 1.2343, 1.2738HH and 1.2738, paired with standardized heat treatment and nitriding. The mold retains stable precision beyond 500,000 injection cycles and effectively lowers your daily maintenance expenses.
