Famous Three Piece Forged Wheels Manufacturer & Precision Products

Three-piece forged wheels combine aerospace-grade 6061-T6 aluminum forged center discs with spun aluminum barrels (inner and outer). Under our 10,000-ton forging process, the metallurgical grain boundary aligns continuously along stress concentration vectors, completely eliminating the shrinkage porosity and microscopic air cavities endemic to cast alloys. This yields roughly 35% higher ultimate tensile strength (UTS) and allows significantly thinner, lighter spoke profiles while exceeding all JWL/VIA load safety ratings.

Air retention is engineered through a mechanical stepped joint between the inner barrel, outer lip, and center disc. During assembly in our cleanroom environment, an aerospace silicone sealant (specifically formulated for high-thermal fluctuations and chemical resistance against brake dust and moisture) is applied uniformly into a CNC-machined containment trench. The assembly is then cross-torqued using high-tensile ARP aerospace hardware. Every assembled wheel undergoes a 24-hour helium and submerged pneumatic immersion test prior to carton packaging.

Yes. Because the forged center blank is machined via multi-axis CNC rather than poured into a fixed mold, we can customize pitch circle diameters (PCD from 4x98 to 8x180, centerlock conversions), center bores (CB hub-centric to the exact vehicle hub within 0.02 mm), and offsets (ET from extreme negative dishes to aggressive high-positive offsets) to clear aftermarket big brake kits (BBK). We cater to specialty vehicle builders, luxury tuners, and wholesale distributors alike.

For bespoke or low-volume orders (1 to 10 sets), typical production spans 20 to 25 working days following 3D CAD design approval and fitment confirmation. For container-load wholesale programs (20ft or 40ft HQ), batch lead times range from 35 to 45 calendar days, inclusive of CNC lathe turning, 5-axis milling, surface hand-finishing, robotic powder coating, ultrasonic bolt torqueing, and JWL destructive quality audits.

Every Kipardo and Rimax wheel undergoes multi-stage surface pretreatment: alkaline ultrasonic degreasing, deoxidizing acid wash, and zirconium conversion coating to ensure optimal primer adhesion. We apply automated electrostatic powder primers followed by UV-stable liquid acrylic colors and automotive-grade acrylic clear coats. Every finish specification is audited with a 1,000-hour CASS copper-accelerated acetic acid salt spray test without bubbling, blistering, or galvanic filiform corrosion.
