Company Overview
Leshan Dongfeng Automobile Electrical Equipment Co., Ltd. (LSDF) is located in the National High‑Tech Industrial Development Zone of Leshan City, Sichuan Province. The company covers an area of 40 acres and employs about 150 people, with a monthly production capacity of over 30,000 starter motors. Guided by the “zero defect” quality management philosophy, the workshop integrates advanced manufacturing equipment, an information management system, and lean production principles to create an efficient, stable, and intelligent modern production system.
Precision Machining & Die‑Casting Workshop
LSDF has built a complete production chain from blank die‑casting to precision machining. Major equipment includes:
| Machining Centers | 2 imported (USA) high‑speed · 20 Brother (Japan) · 2 Brother 4‑axis linkage |
| CNC Lathes | 30+ Saintes CNC lathes |
| Specialized Equipment | 8 multi‑spindle drilling · 8 EDM welding · laser cutting · 150+ other devices |
| Die‑Casting Machines | 3 × 260‑t aluminum · 2 × 650‑t plastic injection |
These machines enable single‑setup, multi‑surface machining of complex precision components, ensuring dimensional consistency and interchangeability. Supported by ERP, CAD/PDM systems, and a professional metrology room (equipped with Hexagon CMM, 2.5D optical projector, DV tester, and Huasheng starter & alternator test benches), the workshop can quickly respond to customized requirements and achieve flexible, small‑batch, multi‑variant production.
Winding & Armature Forming Workshop
The electromagnetic performance of a starter directly determines its reliability. The workshop is equipped with 3 automatic armature production lines and 8 stator winding machines, in addition to field case winding machines and armature wire forming stations. The automated forming processes significantly reduce operator fatigue while improving winding density and accuracy. The precise control of wire angles and length ensures stable and strong torque output during engine start, while effectively controlling product consistency.
Testing & Inspection Center
Quality is the lifeline of LSDF. The independent testing and inspection center features:
| Hexagon CMM — high‑precision 3D measurement of complex geometries |
| 2.5D optical projector — accurate inspection of workpiece structural dimensions |
| DV tester — dedicated durability verification |
| Huasheng starter & alternator test bench — comprehensive performance evaluation |
Before shipment, every batch of starters (12V/24V, 0.6kW – 7.8kW) undergoes strict load testing, endurance testing, and low‑temperature start testing to ensure that all products meet or exceed customer requirements.
Final Assembly & Warehouse Workshop
The final assembly line uses a flow‑line mode combined with the ERP material management system, achieving full traceability from parts picking to finished product output. Error‑proofing devices are installed at key stations, and operators strictly follow standard operating procedures (SOPs) to minimize human errors. An aging test area is also set up inside the workshop, where samples are randomly selected for simulated vehicle start cycling tests.
The warehouse adopts fixed‑position zoning management and uses barcode/RFID technology for precise inventory control, strictly following the first‑in‑first‑out (FIFO) principle to prevent expired or mixed materials.
Management & Innovation Culture
The company spirit – “pragmatism, integrity, service, innovation and development” – is visible throughout the workshop. Quality briefings are held weekly to share improvement cases. As of September 2024, LSDF has obtained 68 National Utility Model Patents and 3 Invention Patents, many of which originated from technical improvement suggestions from shop‑floor employees.
The workshop combines natural lighting with energy‑efficient LED lighting. Aisles are spacious, and equipment layout follows ergonomic principles. Through the ERP/OA system, production plans, equipment status, and quality data can be monitored in real time, and management can perform remote scheduling, achieving deep integration of traditional manufacturing and digital management.
