Precision Driveshaft Systems – Powering Global Automotive Excellence with Unrivaled Performance

As the critical link connecting engines to wheels in automotive powertrain systems, driveshafts bear the vital mission of transmitting torque and ensuring driving stability. As an IATF 16949-certified global leader in driveshaft manufacturing, we deliver high-performance, ultra-reliable driveshaft solutions to world-renowned automotive brands through vertically integrated full industry chain capabilities and cutting-edge manufacturing technologies. Below we detail our core competencies across technical craftsmanship, quality control, and global service.

Full Industry Chain Mastery: Precision Control from Raw Materials to Finished Products
Breaking from traditional OEM models, we maintain complete in-house control over all driveshaft manufacturing processes – forging, machining, heat treatment, grinding, and assembly – ensuring full lifecycle quality management.

1. Precision Forging Technology
   Utilizing 10,000-ton servo presses and intelligent temperature control systems, we implement multi-directional die forging on alloy steel, achieving 30% higher material density and fatigue strength that significantly exceeds industry standards. Finite element analysis optimizes grain flow direction, ensuring uniform internal structure for subsequent processing.
2. Intelligent Machining Systems
   High-precision CNC lathe clusters with integrated inspection systems achieve micron-level tolerance control (±0.005mm) on critical components like flanges and splines. Adaptive tool compensation technology minimizes machining vibration, maintaining surface roughness ≤Ra0.4μm.
3. Deep Carburizing & Quenching
   Controlled atmosphere carburizing furnaces and high-pressure gas quenching create 0.8-1.2mm hardened surface layers while maintaining tough cores. Post-tempering treatment elevates torsional strength beyond 1,800MPa with 5X wear resistance improvement.
4. Ultra-Precision Grinding
   CBN wheel CNC grinders deliver mirror-finish grinding (roundness ≤0.002mm) on bearing seats and journals. Integrated laser measurement enables dynamic compensation for zero-clearance fit with hubs and differentials.
5. Digital Assembly & Testing
   Automated assembly lines incorporate vision-guided robots, closed-loop torque control, and NVH test benches, ensuring 100% compliance through real-time monitoring of:
   • Dynamic balance (residual unbalance ≤1g·cm)
   • Abnormal noise & vibration

Custom Engineering Services: Agile Response to Market Demands
Our modular design platform enables:
• Co-development: 48-hour drawing feasibility analysis with CAE simulation & rig testing validation
• Flexible production: In-house forging capabilities supporting small-batch customization
• Full lifecycle support: Technical teams providing installation guidance, failure analysis & lifespan prediction

From intelligent forging to digital assembly, from process innovation to uncompromising quality, we redefine driveshaft performance benchmarks through full industry chain mastery. Moving forward, we remain committed to advancing precision transmission technologies, delivering smarter, more efficient power transfer solutions to propel the global automotive industry’s transition towards electrification and intelligent mobility.
