Fujian Guanwei Auto Parts Co., Ltd., operating under the brand name GW JDM, has built a four-decade manufacturing history centered on differential products, pin shaft products, stamping parts, and forging products for the automotive, machinery, and engineering sectors. Headquartered in Xiamei Town, Nan'an, Quanzhou, Fujian, China, the company describes its operating philosophy as "compliance as the foundation, green as the wings, innovation as the soul." This review examines the company's history, certifications, product range, and documented customer relationships based on its published enterprise materials.
A Four-Decade Legacy Built on Compliance and Innovation
The company traces its roots to 1985, when it was registered as "Rongshun Auto Parts Factory." Over subsequent decades it underwent several relocations and name changes: to "Quanzhou Xinrongshun Machinery Development Co., Ltd." in 2004, to "Fujian Rongshun Machinery Manufacturing Co., Ltd." in 2012, and finally to Fujian Guanwei Auto Parts Co., Ltd. in 2017, when it also began partnerships with China Longgong Holdings Co., Ltd., Anhui Heli Co., Ltd., Hangcha Group Co., Ltd., and XCMG Forklift.
Growth continued through partnerships with Shaanxi Hande Axle Co., Ltd. (2018), Dana Incorporated and Daimler Mercedes-Benz (2019), and Fangsheng Axle (Liuzhou) Co., Ltd. (2020), the same year the company passed Ux TS16949 quality management system certification and National Safety Production Standardization Level 3 enterprise certification. In 2022 the company obtained National High-Tech Enterprise certification along with Fujian Province "Innovative" SME and "Technology-Based" SME designations, and began working with Jiangling Group Jiangxi Jiangling Chassis Co., Ltd. Additional partnerships followed with SANY China, Shanghai Renben Group, and Guilin Dayu Customer Co., Ltd. in 2023.
In 2024, the company launched digitalization and intelligent engineering, implementing an ERP system, CAXA PLM product lifecycle management, an MES Industrial IoT Platform, and the Weaver digital operation platform, alongside a new partnership with Jinan ChuangKai Technology Co., Ltd. By 2025, the company had passed the ISO three-system certification (ISO9001, ISO14001, ISO45001), established its JDM Business Department focused on overseas high-precision manufacturing, and formed relationships with Fangsheng Axle (Hefei), Caterpillar, Guangxi Yuchai Xinyuan New Energy Power Technology Co., Ltd., Jiangsu Lingyi Automobile Technology Co., Ltd., Foton Motor, Yutong, Sinotruk, Dorman, and NAPA.
Full-Chain Compliance and Certification Strength
A defining feature of Fujian Guanwei's positioning is its full-chain compliance capability. The company holds IATF 16949:2016 certification through TUV SUD Management Services GmbH (certificate number 1211130110T643, valid through November 26, 2028), alongside ISO9001, ISO14001, and ISO45001 certifications issued in 2025. It also carries CE certification for European market access and a RoHS conformity certificate issued by Beijing Kunbiao Inspection and Certification Co., Ltd. (issued May 8, 2025).
As of 2025, the company had applied for 8 invention patents and 36 utility model patents. Its heat treatment operations comply with the CQI-9 standard, while surface treatment operations follow the CQI-12 management system, both administered with senior technical teams to maintain consistent process quality.

Comprehensive Product Portfolio
Fujian Guanwei organizes its manufacturing output into three primary categories, totaling 31 listed products and services.
Differential Products
The differential product line includes the Differential Cross Shaft, built from solid forged steel with oil passage lubrication supporting four planetary gears—supplied to Heli Co., Ltd. for forklift applications. The Fangsheng Axle Planetary Half-Shaft Gear is manufactured in 20CrMnTi case-hardening steel for the HDZ255 single-stage reduction drive axle. The Mercedes-Benz Transfer Case Gear serves as the central differential within the Mercedes-Benz 4MATIC system, distributing power at a typical 45% front / 55% rear ratio across C-Class, E-Class, S-Class, and GLC models. The Jiangling Planetary Gear Shaft supports light commercial vehicle drive axles (0.5–8 tons), engineering vehicle drive axles (3–6 tons), and new energy electric drive axles.
Pin Shaft Products
This category covers cross shafts, output shafts, fork shafts, kingpins, and steel plate pins supplied to Hande Axle across multiple drawing numbers (including HD90149326581/82 and HD469-2510014) for axles ranging from 3.5-ton light truck applications to 40-ton mining vehicle axles. The Dana Steering Knuckle Kingpin (model CK1036) uses 42CrMo quenched and tempered high-frequency material for Sinotruk heavy-duty trucks, while the SCANIA Steel Plate Pin (model 199100520065) applies phosphating with a spiral design and is supplied in large quantities to Sinotruk, Shaanxi Automobile, and Dongfeng. The Caterpillar Universal Joint (model J101030) uses specialized material 1E0778B for excavators, bulldozers, loaders, and mining trucks.
Stamping and Forging Products for New Energy Light Trucks
This line includes support plates, support brackets, spring plates, shock absorber bracket assemblies, spring pressure plates, fixed supports, and engine gear case covers—predominantly built in 20CrMnTi and 40Cr materials for Hande Axle's HDZ255 single-stage reduction drive axle platform used in 3.5-ton motor bridge applications.
