Is Rimax a wheel manufacturer or a trading company?

Shanghai Rimax Industry Co., Ltd. was established in 2010 as an alloy wheel manufacturer and exporter. Our Kipardo casting wheel factory is JWL verified, and our engineering, quality and export teams work directly with importers, distributors and brand owners.

Which wheel types can Rimax supply?

We supply low-pressure cast wheels, flow-formed wheels, forged wheels, off-road 4x4 wheels, OE-style replica wheels and fashion aftermarket wheels, so buyers can source multiple price tiers from one quality system.

What tests do Rimax alloy wheels pass?

Wheels are validated with the core JWL / VIA test items: radial fatigue, cornering fatigue, 13-degree impact and air-leak testing, supported by X-ray inspection, dimensional and run-out checks and salt-spray testing of finishes.

What warranty do Rimax and Kipardo wheels carry?

Every Kipardo wheel is covered by a 5-year / 100,000 km structural warranty and a 2-year warranty on all paint and chrome finishes.

Can Rimax produce OEM or private-label wheels?

Yes. We engineer PCD, offset (ET), center bore and load rating to your fitment list, develop new designs and finishes, and supply private-label caps, stickers and packaging for your market.

Industry Whitepaper

The Evolution of Forged Bronze Wheels in Modern Mobility

Why aerospace-grade 6061-T6 forging coupled with micro-layer bronze PVD/anodization has become the benchmark for hypercars, luxury overland fleets, and next-gen electric vehicles.

Unsprung Weight vs. EV Range

As electric platforms push curb weights higher due to battery packs, reducing rotational inertia is no longer cosmetic—it is structural. Our 10,000-ton forging grain realignment produces wheels that are up to 30% lighter than standard gravity or low-pressure cast wheels, reclaiming valuable range and extending suspension actuator longevity.

Bronze Surface Engineering

Forged bronze finishes demand metallurgical precision. Whether choosing Matte Vintage Bronze, Gloss Champagne Bronze, or Brushed Liquid Bronze, our dual-stage electro-deposition and powder clear-coats resist brake dust pitting, UV degradation, and extreme temperature variations up to 450°C during heavy track or trail cycles.

Monoblock vs. Multi-Piece Dynamics

Our OEM manufacturing lines balance 1-piece Monoblock forgings for rigid track stability with 2-piece and 3-piece modular designs using ARP aerospace hardware. This engineering elasticity allows tier-1 brands and specialty tuners to achieve extreme deep concave profiles and custom widths from 8J to 14J without structural compromises.

Regulatory Assurance

Global Commercial Compliance & Local Engineering Integration

Empowering wheel brands, commercial importers, and regional distribution networks across major trade corridors.

North American SAE J2530 & DOT

All private-label and OEM forged production runs for the US and Canadian markets undergo structural dynamic radial and cornering fatigue benchmarks under strict tire diameter baselines, complete with back-pad stamped DOT-T certification.

Japanese JWL / VIA Certification

Our Kipardo casting and forged plants maintain accredited test benches simulating 13° impact testing, air-tightness verification, and cornering moment fatigue, facilitating smooth vehicle inspection documentation across APAC markets.

European ECE R124 & TÜV Structural Parity

Engineered for high-speed autobahn load requirements, our FEA (Finite Element Analysis) stress simulations calculate maximum shear thresholds at the spoke root, ensuring complete structural validation for premium European vehicle fitments.

Aero-spoke forged geometry configured to smooth brake-disc turbulence, dissipate thermal buildup from regenerative braking systems, and support severe instantaneous torque spikes common in high-output dual-motor architectures.

Strategic Horizons

Engineering Roadmap: Intelligent Wheel Manufacturing

Continuous investment into carbon-aluminum hybrids, zero-emission recycling, and AI-driven topological optimization.

Phase 01 // Structural Topology

AI-Assisted Generative CAD

Implementing finite element stress prediction algorithms directly into our CNC milling paths to carve out unneeded mass from spoke webs without sacrificing lateral stiffness, achieving an additional 6% weight saving.

Phase 02 // Advanced Coating Tech

Hybrid PVD Ceramic Bronze

Transitioning beyond traditional solvent-borne clear-coats toward eco-friendly Physical Vapor Deposition (PVD) micro-ceramic coatings with 9H pencil scratch hardness and hydrophobic salt-resistant properties.

Phase 03 // Composite Hybrids

Forged Carbon-Billet Hybrid Rims

Developing ultra-lightweight hybrid solutions combining a forged 6061-T6 bronze center with a multi-axial carbon fiber outer barrel, targeted at premier hypercar builders and competitive motorsport racing teams.

Technical Knowledge Base

Frequently Asked Questions for B2B Wheel Programs

Expert answers covering metallurgy, custom tooling, minimum order quantities (MOQs), and private labeling.

What specific aluminum alloy is utilized in Kipardo custom forged bronze wheels? +

All our custom forged wheels are exclusively carved from aerospace-grade 6061-T6 aluminum billets. Unlike 6063 or secondary recycled alloys, 6061-T6 contains strictly controlled proportions of magnesium and silicon, solution heat-treated and artificially aged to achieve a tensile strength exceeding 310 MPa. This allows us to mill exceptionally slim spokes with deep concave profiles while exceeding international JWL/VIA and SAE safety limits.

How does Shanghai Rimax ensure finish consistency across bronze wheel batches? +

Bronze is one of the most demanding color spectra in automotive coating. We utilize computer-monitored electrostatic powder coating alongside automated PVD chambers. Every single production batch is calibrated via spectrophotometer to match delta-E color tolerances (ΔE < 0.8), followed by a 720-hour ASTM B117 salt spray exposure test to ensure complete resistance against winter road salts and brake fluid corrosives.

Can Rimax manufacture private-label forged wheel programs with low MOQs? +

Yes. Because custom forged wheels are carved directly from solid billet stock via 5-axis CNC machining rather than cast from permanent steel molds, we offer flexible production parameters. For aftermarket wheel brands and specialty tuning shops, our bespoke forged wheel program starts with an MOQ as low as 4 pieces (1 vehicle set) per custom design/fitment, while offering high-volume container pricing for established distributors.

What are the exact structural warranty terms on Kipardo and Rimax wheels? +

Every Kipardo forged wheel includes a comprehensive 5-year / 100,000 km structural warranty against material delamination, fatigue cracking, and structural failure under proper road and track operation. In addition, all paint, bronze anodization, and clear finishes carry a 2-year warranty against peeling, clear-coat yellowing, or corrosion, supported by formal batch inspection certificates.

What technical fitment parameters can be customized for OEM buyers? +

Every operational variable is fully customizable: Pitch Circle Diameter (PCD from 4x98 up to 8x180), wheel offsets (ET from -50mm to +65mm), center bore diameters (precision hub-centric machining for zero vibration), back-pad pocketing for big brake kit (BBK) clearance, knurled bead seat grooving, and customized central cap engraving or floating cap mechanisms.
