Continental AG, Germany: Customized Brake System Sensor Case
Precision Machining of Automotive Safety Parts
As a global leader in automotive safety systems, Continental needed to customize a batch of brake pressure sensor components with a tolerance of ±0.003mm and required delivery within 30 days. A precision manufacturing enterprise completed the delivery of 5,000 pieces 2 days ahead of schedule through ultra-precision turning centers and a digital quality traceability system. The products passed the German DIN EN ISO 13485 medical-grade extended certification (special requirements for automotive safety parts) at one time, with a yield rate of 99.92%. Eventually, it became a strategic supplier for Continental in Europe, with its annual order share increasing to 25%.
DENSO (Japan): New Energy Motor Shaft Parts Project
Intelligent Assembly Line Upgrade Project
For a hybrid vehicle’s high-speed motor, DENSO needed to customize titanium alloy shaft parts with a tolerance of ±0.002mm and require delivery within 40 days. A domestic enterprise optimized the vacuum heat treatment process and applied six-axis linkage machining technology. It not only delivered the products on schedule but also improved the dynamic balance precision of the parts to 1.5 times the industry standard. The products passed the Japanese JIS D 4401 automotive parts reliability certification. Subsequently, it obtained 30% of DENSO’s new energy shaft parts orders in China.
TRW (USA): Autonomous Driving Steering System Component Case
Bulk Procurement Project for Stainless Steel Brackets
TRW needed custom valve core components with a tolerance of ±0.004mm for the steer-by-wire system developed for L3-level autonomous driving vehicles, with a delivery cycle of 35 days.
A company completed the delivery of 2,000 sets of products 4 days ahead of schedule by leveraging an AI visual inspection system and flexible production line scheduling. The products achieved a yield rate of 99.85% and successfully passed the U.S. SAE J2954 safety certification for autonomous driving components.
Ultimately, the company successfully entered TRW’s North American supply chain and subsequently secured 30% of the prototype orders for steering system components in TRW’s global new vehicle models.
