1.Product Introduction
Kaihua's Automobile Plastic Part Car Pillar Mould belongs to the company's automotive interior system mould category, dedicated to manufacturing A-pillar, B-pillar, and C-pillar parts for vehicles. The product is developed to meet the needs of global automotive markets, serving not only Chinese national brands (SAIC, Geely, BYD) and joint-venture brands (FAW-Volkswagen, BBAC, Shanghai GM) but also international premium brands (McLaren, Tesla, Mercedes-Benz) and Tier 1 suppliers (Yanfeng, Faurecia, Magna).
To ensure durability and precision, the mould adopts premium materials: mold steels from Buderus (Germany), BAOSTEEL, and LKM; hot runners from global top brands like YUDO and Kyuventive; and standard parts from MISUMI (Japan) and HASCO (Europe). It is processed by top-tier 5-axis machining equipment (e.g., MAKINO, FIDIA, DMG), achieving an industry-leading tolerance to guarantee seamless compatibility with automotive assembly lines.
In addition, two of Kaihua's prominent Automobile Plastic Injection Molds—the Headlight Cover Mould-Double Color Mould and the Car door mould—have received wide praise in the industry.
