As an OEM forged rim supplier, Zhigu produces rims to exact automaker specifications, ensuring seamless compatibility with vehicle dynamics (load capacity, balance, speed rating). Using 6061-T6 forged aluminum, these rims offer 40% higher strength and 30% weight reduction compared to cast alternatives, meeting ISO/TS 16949 and OEM-specific testing protocols (such as BMW's 20,000km rough road simulation). Services include logo integration, 3D design validation via FEA analysis, and traceable batch production with laser-engraved part numbers. Applications span luxury sedans (e.g., Audi A8), electric vehicles (e.g., Tesla Model S), and high-performance sports cars (e.g., Porsche 911).
