Dingxing Engine Plant
Located in Dingxing, Baoding, Hebei Province, The first engine plant was founded in May 2000, covering 230,000 square meters.
It mainly produces 2.0L diesel engines, 491 platform engines, cylinder blocks, heads, crankshafts and small components.
It has a complete R&D, production, supply and sales system, focusing on solid carbide tools, indexable tools and tool regrinding services.
Machining Workshop
It has a total of 10 production lines, including two machining workshops: the ED machining line and the EC machining line for balance shafts and oil pans.
Automated Equipment Unit
The crankshaft production line adopts flexible processing, with full automatic loading and unloading by articulated robots, realizing fully automatic production.
Key Process (Follow Grinding Process)
For finish machining, grinding machines from Landis (UK) are adopted. The follow grinding machines feature grinding precision with roundness within 3 μm, cylindricity within 4 μm, and connecting rod neck parallelism of approximately 8 μm.
Honing Unit
It adopts German Nagel honing machines and plate honing technology to achieve high-precision machining of cylinder bores and main shaft holes.
Finishing Equipment
The finishing equipment for the ED cylinder block and cylinder head line is implemented by high-speed machining centers from Germany DMG and Mazak (Little Giant).
In terms of process, technologies such as rigid drilling, rigid tapping, high-speed CBN tools and high-speed diamond tools are adopted.
Assembly & Test Workshop
Including assembly / test-run line and test-run line
Hot Test Process
100% hot test within 8 minutes to test engine performance under various working conditions, capable of detecting 242 types of faults.
Tightening Machine
The full-axis tightening machine realizes synchronous tightening of all bolts. It automatically monitors and alarms for abnormal torque, and automatically notifies responsible personnel, achieving torque traceability.
Gluing Machine
The gluing process is subject to real-time monitoring, photography and traceability, with a sample comparison function.
Press Machine
When installing circlips, 100% proper press fitting is ensured by vision scanning, preventing missing or incomplete fitting.
Rotational Torque Tester
100% inspection of the cylinder block rotational torque, effectively detecting abnormal cylinder blocks, bearings, crankshafts, and thrust plates with traceability.
