Explore our export-ready cast, flow-formed, and luxury forged catalog with precision automated surface buffing treatments designed for rigorous road conditions.
Achieving defect-free, mirror-gloss, and crystal-clear reflective finishes demands micro-grit abrasives, algorithmic force control, and multi-stage chemical passivation.
By leveraging 6-axis multi-articulated mechanical arms, our buffing lines dynamically trace complex spoke geometries and deep concave barrels with constant tool pressure (±1.5N), preventing thinning of structural corners.
Multi-step abrasives transition from 320-grit silicon carbide down to non-woven flap discs and high-purity aluminum oxide buffing bars, systematically achieving surface roughness of Ra < 0.05 μm.
Automated buffing removes casting flash and micro-notches, effectively closing microscopic stress concentration points on spoke roots and significantly increasing dynamic radial fatigue performance.
Combining vertically integrated smelting, robotic casting, heat-treatment, precision CNC, and surface finishing under an intelligent digital footprint in Kunshan, Jiangsu.
Direct low-pressure feeding of virgin A356.2 aluminum alloys with rotary argon degassing reduces dissolved hydrogen levels to below 0.10 cm³/100g, preventing subsurface blistering during high-speed buffing.
Each wheel is etched with a laser Matrix code. Real-time logging of mold pressures, quenching parameters, run-out concentricity, and buffing cycles ensures 100% batch traceability.
Situated within the Greater Shanghai automotive corridor, Rimax guarantees swift procurement of molds, aerospace-grade billets, and packaging, shortening custom prototype lead times to under 21 days.

Beyond visual mirror polishing, every batch undergo destructive and non-destructive testing to exceed international traffic safety regulations.
Wheels rotate against a smooth drum with load applied through the hub up to 500,000 cycles, verifying resistance against long-term operational stress fractures.
A calibrated drop weight strikes the wheel rim flange at an acute angle to verify energy absorption and ensure structural retention without catastrophic rim separation.
100% digital fluoroscopy exposes any internal porosity, shrinkage cavities, or slag inclusions before wheel buffing lines proceed to final air-leak sealing checks.
Polished and clear-coated wheels endure 720+ hours of continuous neutral salt spray (ASTM B117) to ensure zero filiform corrosion under humid winter highway conditions.
Addressing supply-chain volatility, brand differentiation, custom offsets, and rapid freight dispatch for international distributors.
OEM engineering covering custom bolt circles (PCD: 4-lug, 5-lug, 6-lug, 8-lug), center bore matching, CNC embossed branded center caps, custom color boxes, and barcode pallet labeling.
Flexible container loads (FCL) allow buyers to blend fast-moving cast 4x4 off-road rims, premium flow-formed sports models, and bespoke forged wheels inside one single shipping shipment.
Complete customs and regulatory dossiers: factory JWL inspection reports, mill material certs, SASO certificates, and complete COC records for tariff clearance across North America, Europe, and GCC.
Direct engineering responses to technical questions encountered by procurement managers, automotive engineers, and wheel importers.
Our manufacturing plant operates robotic rotary multi-head buffing stations combined with programmable multi-axis CNC machines. Rather than relying entirely on manual buffing wheels which introduce operator fatigue variances, robotic arms apply constant contact force across 100% of the surface. We utilize automatic liquid compound dispensing to maintain precise abrasive paste viscosity and run optical profilometer scans (Ra checks) per production batch to guarantee an Ra value below 0.05 μm.
Polished aluminum is highly vulnerable to atmospheric oxidation. Following buffing, parts undergo an automated 7-stage chemical conversion wash (zirconium/silane pre-treatment) that creates an inert nano-thin passivation layer. We then immediately apply an electrostatic high-clarity polyester powder primer, followed by an acrylic protective clear coat cured in high-temperature ovens. This barrier protects against salt spray, chemical cleaners, and acid rain, achieving 720+ hours of ASTM B117 salt spray resistance.
Yes. Shanghai Rimax Industry Co., Ltd. provides full fitment engineering. We customize Pitch Circle Diameter (PCD 98mm to 180mm), offset / ET ranges from -44mm up to +60mm, center bores (CB), and hub-centric rings to precisely align with your application requirements. Our engineering team conducts virtual 3D caliper clearance simulations prior to tooling fabrication to ensure unobstructed brake caliper clearance.
Every Kipardo wheel produced is covered by a 5-year / 100,000 km structural warranty, protecting distributors against internal casting defects, metal fatigue cracks, and structural deformation under standard highway loads. Surface treatments (including machine-face, polished buffing, candy paint, and chrome coatings) are backed by a comprehensive 2-year warranty covering clear coat adhesion, filiform corrosion, and peeling.
For existing cast molds, standard wholesale MOQ is typically 60 to 80 pieces per SKU, with production lead times averaging 30 to 40 days from deposit. Bespoke 1-piece, 2-piece, and 3-piece forged wheels can be ordered with low MOQs starting from 4 units (one set), with rapid CNC machining turnarounds within 15–20 days.
