Precision Forged & Cast Engineering Inventory (Part I)
Ultra-high dynamic capacity wheel assemblies built to rigorous JWL/VIA and European CE structural requirements.
The 22-Inch Forged Wheel Paradigm: Structural Physics Meets Automotive Evolution
In modern high-performance SUV, electric vehicle (EV), and luxury passenger vehicle segments, 22-inch wheel fitments have transitioned from optional cosmetic upgrades to fundamental dynamic requirements. Managing un-sprung mass while providing exceptional torsional rigidity under instantaneous peak torque loads requires an absolute migration from traditional casting to aerospace-grade 6061-T6 monoblock and modular forged systems.
Coping with High Instantaneous EV Torques
Heavy curb weights in modern performance electric vehicles deliver instant torque spikes exceeding 1,000 Nm. Traditional cast wheels suffer micro-fracturing along spoke radiuses over prolonged duty cycles. A monoblock forged rim preserves continuous structural grain lines, preventing rim slip and bead unseating.
Rigid Compliance with CE & Continental Safety Directives
CE Certification demands strict alignment with EU Directives on general vehicle component safety, dimensional precision, and material purity. Shanghai Rimax Industry combines European regulatory benchmarks with JWL, VIA, and SAE J2530 protocols for total legal compliance.
Resonant Frequency & NVH Attenuation
Large 22-inch wheel cavities create harmonic air cavity resonance, transmitting road noise into modern sound-dampened cabins. Our 3D computational structural designs incorporate variable spoke geometry and acoustic dampening ridges directly into CNC profiling routines.

Thermal Dispersion Under Heavy Braking
Large 22" rims frequently house massive carbon-ceramic or multi-piston steel brake calipers. The molecular density of forged 6061-T6 conducts thermal energy away from brake assemblies 22% faster than porous cast alloys, mitigating fluid boiling and brake fade during track or alpine descents.
Multi-Axis High-Speed CNC Sculpting
Using 5-axis German high-speed CNC centers, our forged blank conversion achieves tolerances within 0.05 mm. Intricate spoke undercuts, concave geometry profiles, and back-pad pocketing maximize lightness without compromising finite-element-analyzed structural pathways.
Microstructural Consistency via T6 Aging
Solid-solution heat treatment followed by artificial aging uniformly disperses magnesium-silicide (Mg2Si) precipitates across aluminum crystal boundaries, unlocking maximum fracture toughness throughout the wheel barrel, bead seat, and center hub.
