Electric Vehicle Mass Compounding
The rapid transition toward high-capacity battery electric platforms (gross vehicle weights exceeding 2.8 metric tons) has rendered conventional gravity-cast wheels obsolete for 22-inch fitments. CE-certified 6061-T6 forged architectures bridge the vital gap between astronomical curb weight, instant torque transfer, and aerodynamic rolling resistance minimization.
Strict CE Mark Import Protocols
European Union directives and customs jurisdictions enforce rigorous traceability protocols on alloy structural components under the Construction Products Regulation (CPR) and automotive homologation rules. Rimax supplies pre-cleared documentation covering metallurgical material sheets, dynamic cornering endurance records, and finite element analyses.
Aftermarket Margin Consolidation
High-end tuning companies and distributors face margin compression across standard 17-19 inch cast wheels. The 22-inch forged segment delivers a high-margin product class characterized by low price sensitivity, customized offset specifications, custom multi-piece finishes, and brand equity building for enterprise importers.

Industry 4.0 Infrastructure
Precision Fabrication Flow: Billet to CE Homologation
Eight systematic quality control stages ensuring each 22-inch forged wheel exhibits zero radial runout and optimal fatigue resistance.
01
Billet Heating & Pre-Form
Aerospace-grade 6061 aluminum alloy cylinders undergo precision induction heating to 480°C, preparing the crystalline structure for high-pressure molecular alignment.
02
10,000-Ton Hydraulic Forging
Closed-die multi-directional forging collapses atomic voids, increasing structural integrity and achieving an unbroken radial flow pattern throughout the wheel center.
03
T6 Solution & Artificial Aging
High-temperature solution heat treatment followed by rapid water quench and artificial aging locks alloy elements into a rigid intermetallic precipitation matrix.
04
5-Axis CNC Precision Milling
High-speed milling machines carve complex concave profiles, back-pad weight-saving pockets, and brake-caliper clearance pockets to 0.01mm tolerances.
05
Ultrasonic & X-Ray Testing
Non-destructive radiographic examination and immersion ultrasonic checks verify that every forged spoke and hub core is free from subsurface inclusions.
06
Surface Passivation & Coating
Multi-stage chemical pre-treatment, zirconium conversion coating, electrostatic powder primer, and hand-brushed or diamond-cut clear coat finish.
07
Dynamic Rig Testing
Empirical dynamic radial fatigue, rotating bending cornering checks, and 13° drop-weight impact verification simulate 300,000 kilometers of road stress.
08
Export Pack & Homologation
Protective wheel-edge rings, static-free fleece covers, heavy-duty honeycomb double cartons, and international pallet wrapping with CE/JWL certificates.
Deployment Scenarios
Localized Engineering Applications for 22" Forged Systems
From harsh northern winter salt roads to desert hyper-load terrain, our 22-inch wheel architectures are tailored to regional operational demands.
GCC High-Temperature & Desert Overlanding
Engineered for high radiant heat transfer and extreme hub torque across high-payload platforms including the Nissan Patrol Y62, Toyota Land Cruiser 300, and Cadillac Escalade. Reinforced inner rim beads resist low-tire-pressure de-beading in soft sand dunes while specialized thermal coatings accelerate brake disc heat dissipation in ambient 50°C climates.
European Autobahn High-Speed Dynamic Balance
TÜV-standard compliance requires structural resistance to sustained high-speed compression forces exceeding 250 km/h. Precision back-pad pocketing and low rotational inertia reduce gyroscopic resistance on executive wagons and sports SUVs like the Porsche Cayenne, BMW X5M, and Audi RSQ8, preventing steering shudder and high-speed harmonic vibration.
North American EV Light Truck & Range Extension
Optimized for Class 2a/2b electric workhorse and luxury pickups such as the Rivian R1T, Ford F-150 Lightning, and Tesla Cybertruck. Lightweight monoblock forging trims up to 40 kg of rotating mass compared to OEM wheels, directly clawing back 4–7% in combined city/highway driving range while offering massive 1,150 kg static load ratings per corner.
Enterprise Solutions
Macro Supply Chain Challenges & Rimax Mitigation Roadmaps
How our Kunshan manufacturing campus helps tier-1 importers hedge anti-dumping tariffs, raw material volatility, and inventory overhead.
LME Aluminum Index Hedging
Aluminum cash settlement prices on the London Metal Exchange introduce severe landed-cost variance. Rimax offers long-term purchasing contracts tied to rolling raw-material reserves, sheltering distributors against quarterly pricing surges and locking in margins throughout annual product cycles.
SKU Proliferation & Low-MOQ Forging
Traditional cast wheels require minimum order quantities of 60 to 100 units per mold. Rimax solves inventory stagnation by offering flexible CNC forging programs starting at 4 pieces per bespoke fitment, allowing retailers to service bespoke customer orders without tying up capital in slow-moving warehouse inventory.
CE, JWL & TÜV Documentation Support
Complex regional customs rejections can stall full container loads. Our export compliance office supplies full homologation dossiers, complete material test certificates (MTC EN 10204 3.1), salt-spray corrosion reports (exceeding 720 hours CASS test), and load calculation sheets with every invoice.

Technical Clarifications
Frequently Asked Technical & Commercial Questions
In-depth engineering answers covering CE certification protocols, load ratings, structural warranties, and private-label packaging.
What specific standards must a 22-inch forged wheel pass to achieve genuine CE certification?
For CE compliance in automotive load-bearing components, wheels must satisfy stringent impact, fatigue, and material criteria mapped to European road safety directives. This includes a 13-degree dynamic impact test (simulating violent curb impacts without catastrophic air pressure loss or crack propagation), a cornering fatigue test (applying over 100,000 cycles of bending moment to the wheel hub), and a dynamic radial fatigue test (rolling loaded fatigue test exceeding 500,000 cycles). Rimax backs every batch with full documentation verified by third-party testing labs.
Is Rimax an actual alloy wheel manufacturer or an export trading intermediary?
Shanghai Rimax Industry Co., Ltd. was founded in 2010 as an integrated manufacturer and exporter. Our dedicated Kipardo casting and CNC forging facilities in Jiangsu, China, are officially JWL/VIA verified. Our engineering, metallurgical R&D, and global export teams work directly with Tier-1 wheel importers, private-label distributors, and tuning companies without intermediary markups.
What alloy types and wheel manufacturing processes can Rimax supply?
We provide a unified quality ecosystem spanning five primary manufacturing processes: Low-Pressure Cast (A356.2 alloy for cost-effective wholesale volume), Flow-Formed (rotary-forged barrels offering balanced weight and pricing), Aerospace Monoblock Forged (6061-T6 aluminum carved on 5-axis CNCs), Multi-Piece Modular Forged (2-piece and 3-piece rims with forged centers and spun barrels), and Heavy-Duty 4x4 Off-Road wheels with reinforced load ratings.
What warranty protection covers Kipardo and Rimax forged wheels?
Every forged and cast wheel manufactured by Rimax carries a standard 5-year / 100,000 km structural warranty covering structural failure, spoke fracture, and hub fatigue under rated load usage. Furthermore, all our surface finishes—including electroplated chrome, brushed translucent powder coat, diamond-cut faces, and painted finishes—are protected by an extensive 2-year surface and anti-corrosion warranty.
Can Rimax support custom PCD, offset (ET), and private-label branding for aftermarket distributors?
Yes. We offer turnkey OEM/ODM engineering services. We tailor PCD (4, 5, 6, and 8-lug patterns including 5x112, 5x120, 5x130, 6x139.7), offset tolerances down to +/- 1mm, center bore dimensions, and brake caliper clearances based on exact 3D vehicle scans. Additionally, we provide private-label branding including custom CNC engraved center caps, branded valve stems, protective fleece ring bags, and custom carton packaging printed with your barcode skus.
How does unsprung weight reduction in 22-inch forged wheels impact electric vehicle efficiency?
Unsprung rotating mass requires significantly more kinetic energy to accelerate and brake than static chassis mass. A set of 22-inch 6061-T6 forged wheels shaves approximately 30 to 40 kg of total unsprung weight off an EV compared to equivalent-sized cast wheels. This reduction yields a 4% to 7% increase in usable driving range, improves damper response over high-frequency surface bumps, reduces regenerative braking thermal loads, and sharpens cornering turn-in response.
