Import 2018 Newest Customized Auto Door Hinge — Buy in Bulk from Supplier in China

This customized auto door hinge is manufactured by Ningbo Chengzhan Auto Parts Co., Ltd. in Yuyao, Zhejiang, China, designed for vehicle door assemblies requiring precise fitment and reliable operation. The hinge is built for repeated open-close cycles typical of automotive applications, with the supplier's own description indicating it is a 2018 design iteration intended for customised vehicle platforms rather than generic aftermarket use.

Automotive door hinges of this class are typically produced from stamped steel or zinc alloy components, with surface treatments such as electrophoresis coating or zinc plating to resist corrosion. Typical hinge assemblies include a pivot pin, mounting brackets, and sometimes a check mechanism to hold the door at set positions. Industry-standard tolerances for automotive hinges generally fall within plus or minus 0.1 to 0.2 millimetres on critical mounting dimensions to ensure consistent door alignment and seal compression.

Buyers of this product are typically automotive OEMs, tier-one parts suppliers, and vehicle assemblers sourcing replacement or custom-spec hinges for specific vehicle models. Ningbo Chengzhan lists major clients including BYD, Volkswagen, Ford, Mazda, Honda, and Toyota, suggesting the product is positioned for volume procurement rather than retail sale. Trade terms, minimum order quantities, and lead times are not published on the listing, so importers should request these directly from the supplier along with sample availability and tooling charges for custom specifications.

Ningbo Chengzhan Auto Parts Co., Ltd. is based in the Yuyao Industrial Development Zone, Zhejiang, China, and was formally established in 2016 after transitioning from CiXi Chengzhan Hardware Co., Ltd., a hardware and small appliance business founded in 2000. The company shifted its focus to automotive parts manufacturing from 2010, and now operates with over 85 employees across 10 departments including Quality Control, Technical, Molding, and Production.

The supplier operates two workshops dedicated to stamping and assembly, and holds ISO 9001 certification obtained in 2008 along with TS 16949 certification from 2012, which is rechecked and updated annually. Their listed client portfolio includes major automotive brands such as BYD, Volkswagen, Ford, Mazda, Honda, Toyota, Nissan, and commercial vehicle makers like Yutong Autobus and JMC. The listing does not publish response rate data, so buyers should expect to allow time for initial contact and clarify communication channels directly with the supplier.
