Abstract:
The present invention relates to an aluminum wheel and a manufacturing method thereof, and more particularly, to an aluminum wheel and a manufacturing method thereof where a resonator structure with sound absorption characteristics is integrally formed. More particularly, the present invention relates to an aluminum wheel applied to a transferring vehicle, comprising a rim where a tire is mounted; a resonator, which is integrally formed with the rim through a molten core combined with the outer peripheral surface of the rim; and one and more resonator holes, which are formed on the outer peripheral surface of the rim so that a vibration waveform can pass through the inside of the resonator. The resonator holes are a passage for melting and discharging the molten core. According to the present invention, provided is an integrated sound absorption aluminum wheel where the molten core is applied.

Abstract:
Disclosed are a manufacturing method of a vehicle wheel nut and the wheel nut. The manufacturing method comprises a preparation step for annealing and warming up an aluminum alloy material; a molding step for molding the warmed material into a wheel nut through a forging process; a first coating step for coating the molded wheel nut with a protective oxide film by anodizing; a second coating step for coating the firstly coated wheel nut through a vacuum deposition surface processing method; and a third coating step of processing the surface of the secondly coated wheel nut using powder coating.
