Manufacturing capability

Manufacturing capability is presented as evidence: process ownership, equipment list, inspection flow and metric definitions follow management-confirmed information.

Manufacturing overview

The joint manufacturing system operates a base of approximately 8,000 m² with 26 listed core machining units (Qinchuan CNC machines, lathes, horizontal machining centers, gear hobbing and gear grinding machines), forming a project chain covering key component machining, assembly, inspection, packing, delivery and after-sales tracking.

In-house core processes

Gear, shaft and key transmission component machining, assembly and inspection capability (management-confirmed scope).

Partner supply chain

Non-in-house processes are completed by long-term supply partners under final control of the joint system.

Integrated supply products

Certain categories are integrated supply, managed by the actual production route and quality requirements.

Listed core machining equipment

The list covers 26 units across five confirmed equipment categories — not the total plant count (source: CLAIM-CF-EQUIPMENT-LISTED-TOTAL-026). Equipment photos to be added.

Manufacturing and inspection process

Steps follow the actual production route; only applicable processes are listed.

01
Incoming material inspection
Dimension, appearance and hardness checks on raw material and parts
02
Rough machining
Rough turning and milling to remove stock
03
Heat treatment
Quenching/tempering or carburizing per process route
04
Gear hobbing
Gear tooth cutting
05
Gear grinding
Gear tooth finishing
06
Housing machining
Boring, milling and mounting face machining
07
Assembly
Cleaning, assembly and adjustment
08
Running test
Run-in test covering noise, temperature rise and sealing
09
Final inspection
100% final inspection of dimensions, running, noise, temperature and sealing
10
Painting and packing
Coating and export packing

Quality control

Incoming inspection → in-process inspection → final inspection: 100% of finished products undergo appearance, dimension, running, noise, temperature rise and sealing checks, with records retained.
