Precision zinc and aluminum die casting, CNC machining and assembly under one roof

COMPANY PROFILE

Who we are

Jinxiong Motor Components Co., Ltd. is a manufacturer specialising in precision zinc and aluminum die casting and finished-assembly production. Its manufacturing roots reach back to the Jinxiong motorcycle carburetor works founded in 1998. A carburetor has to be pressure-tight, hold a precise bore pattern and pass a functional test as a finished assembly — demands that took the company out of the as-cast-only model from its earliest days and onto a precision, full-process route.

Production is headquartered in Fuding, Fujian province, across the Jinxiong and Jinming plants — 22,000 m² between them. Ten die-casting machines from 160 to 800 tonnes run zinc and aluminum castings from 20 g to 5.5 kg, backed by 30+ machining centres, 30+ CNC lathes and 50+ drilling and tapping units — 360+ machines in all once processing and ancillary equipment is counted. Annual capacity runs to three million zinc and aluminum castings and finished assemblies. The quality management system is certified to ISO 9001:2015.

Our parts go into motorcycles and electric two-wheelers, general-purpose power and garden machinery, heat-dissipating structural housings, pump and valve fluid components, and consumer hardware. In China we have supplied QJMOTOR, Loncin and Jialing — leading OEMs in the sector — over many years, and have repeatedly been named an excellent supplier. Export business runs under the JINXIONG brand, serving customers in more than twenty countries.

  • Integrated die-casting and precision-machining OEM
  • 25+ years building complex functional parts
  • Volume delivery proven at leading OEMs

MANUFACTURING

Inside the plant

Two plants of our own in Fuding — Jinxiong and Jinming, 22,000 m² between them. Ten die-casting machines run both zinc and aluminum, with 360+ production machines in all and 26 in-house patents driving continuous automation. Certified to ISO 9001:2015, with an annual capacity of three million parts.

The casting shop

Ten die-casting machines from 160 to 800 tonnes run both zinc and aluminum, with part weights from 20 g to 5.5 kg. The shop is equipped with central melting and holding furnaces, automatic spraying, automatic part extraction and die-temperature control. Samples are retained from every melt batch, so each casting can be traced back to its furnace heat number.

WHY US

Why work with us

End-to-end delivery

Tooling, die casting, machining, surface finishing, assembly and packing are delivered as one integrated process, and every finishing operation is coordinated and owned by us. You can buy castings on their own or hand us the whole chain — either way there is no need to manage multiple suppliers.

Stable lots, controlled cost

We hold 26 patents of our own, focused on special-purpose shop-floor machines and automated lines. Verified in our own plant, these automation upgrades have cut overall production cost by up to 30% while keeping lot-to-lot quality stable — a lasting cost advantage for you.

A wide fit

Ten machines from 160 to 800 tonnes, zinc and aluminum alike, covering parts from 20 g to 5.5 kg. Large and small parts run in the same plant, so a programme need not be split between suppliers.

Built for difficult parts

We have long run clutch assemblies, geared parts, pressure-tight housings and precision bore patterns. Casting and machining close the loop inside one plant, finished goods get 100% functional testing, inspection reports of every kind are available, and on-site audits are welcome.
