Problems solved by technology

Compared with the existing low-pressure die-casting aluminum wheels, when the aluminum forging material and high-hardness treatment are applied to the wheels, the weight can be reduced by about 10%, but the manufacturing cost increases to about 3 to 5 times compared with the low-pressure die-casting aluminum wheels or more high cost, and therefore, the use of aluminum forged and hardened materials is limited
[0009] In the case of a weight reduction of about 10%, since the wheel rigidity is also reduced, a problem of deterioration of road noise, etc. may occur, and in addition, a method for significant weight reduction has not been developed so far

Abstract

A method of manufacturing an aluminum wheel for a vehicle includes preparing a low density material having particles pulverized. A binder is supplied to the low density material so that the low density material is mixed in a paste state. A wheel core manufacturing mold is heated to 200 to 350° C. and injected into the wheel core manufacturing mold. The wheel core manufacturing mold is closed, a pressure of about 5 to 20 bar is applied, the pressure is maintained for 1 to 5 minutes to solidify the low density material, and the wheel core is ejected. The ejected wheel core is mounted on an aluminum wheel casting mold. The aluminum wheel casting mold is closed, and a pressure of about 1 to 2 bar is applied, and an aluminum molten metal is injected. The aluminum wheel is then ejected from the aluminum wheel casting mold.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2014-0031680 filed with the Korean Intellectual Property Office on March 18, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an aluminum wheel for a vehicle and a manufacturing method thereof, and more particularly, to an ultra-light high-rigidity aluminum wheel for a vehicle in which the rigidity of the wheel can be increased and the weight reduced, and a manufacturing method thereof. Background technique [0004] Vehicle wheels can be broadly classified into steel wheels and aluminum wheels. Among them, aluminum wheels have been mass-produced due to implementation into various colors and shapes and weight reduction effects compared to steel wheels, and thus are applied to various types of vehicles produced in mass. [0005] In particular, aluminum wh...
