High-Quality Three Piece Rim Suppliers & Exporters

The Center Center Disk

Forged from aerospace-grade 6061-T6 aluminum using 10,000-ton hydraulic forging presses. The grain flow is oriented along spoke stress axes to ensure structural integrity and optimize unsprung rotating mass.

• Engineered for high-clearance Brembo/Akebono big brake kits (BBK)
• Custom PCD drillings (5x112, 5x120, 5x130, 6x139.7) down to ±0.02mm
• Finite Element Analysis (FEA) verified for rotational shear loads

Spun Outer Rim (Lip)

Manufactured through rotary flow-forming and cold-spin technology from 5051/6061 alloy sheets, resulting in exceptional tensile strength along the outer rim flange where curb impact loads concentrate.

• Step-lip, reverse-lip, and double-step lip profiles available
• Finishes: High-mirror hand polished, brushed bronze, anodized, chrome
• Width variations from 1.0 inch up to 8.0 inch extreme deep-dish configurations

Inner Barrel & Sealing

The inner barrel supports 60-70% of vehicle cornering load. Sealed with aerospace-grade elastomeric silicone polymers and secured with M8 high-tensile titanium or Grade 10.9 forged steel hardware.

• Multi-layer anti-vibration torque lock washer assemblies
• Continuous helium-detection air leak testing on 100% of finished rims
• Engineered barrel knurling to eliminate high-horsepower tire bead slip

Upstream Aluminum Clustering

Our Kunshan facilities operate within direct proximity to China's premier 6061 aerospace alloy extrusion mills. Continuous material supply guarantees certified aluminum billet chemistries free of sub-surface impurities, mitigating global raw material price swings for our contracted international distributors.

5-Axis CNC Precision Ecosystem

Equipped with ultra-high precision Japanese Okuma and Haas 5-axis CNC machining centers. Rimax achieves surface tolerances within ±0.01mm, ensuring exact outer/inner barrel bolt circle mating, zero runout imbalances, and absolute seal longevity under extreme high-speed track vibration.

Logistics & Port Connectivity

Located immediately adjacent to the Shanghai Maritime Shipping Port and Ningbo Port corridors. Finished wheel orders transition seamlessly into FCL/LCL ocean containers or express air freights, shortening total shipment transit times to North American and European fulfillment hubs by up to 12 days.

International Testing Protocols

Every modular wheel engineering design undergoes rigorous validation against global statutory frameworks:

• JWL / VIA (Japan): Dynamic radial fatigue (500k revs) and 13° impact tests
• SAE J2530 (USA): Cornering fatigue and rotary moment deflection validation
• TÜV Festigkeitsprüfung (Germany): High-load rim bending moment benchmarks

Private-Label OEM / ODM Incubation

We empower tuning houses, retail tire chains, and motorsport brands to launch bespoke product lines with complete confidentiality:

• Custom engraved center caps, CNC rim edge branding, and bespoke box design
• Comprehensive 3D rendering catalogs, engineering CAD data, and fitment charts
• Territory exclusivity agreements for dedicated custom mold geometries

5-Year Kipardo Structural Warranty

Backed by Shanghai Rimax Industry’s dedicated export risk management system:

• 5-Year / 100,000 km: Complete warranty covering structural cracking or defect
• 2-Year Finish Guarantee: Protection against clearcoat peel, chrome pit, and corrosion
• Rapid replacement air-freight logistics for any verified manufacturing defect
