Japanese Patent JP2004261846
Kind Code:
A
Abstract:
To provide a manufacturing method of an aluminum wheel for improving the acceptance rate of an aluminum wheel.
This method is a manufacturing method of the aluminum wheel 1 which has a casting stage, heat treating stage, machining stage and painting stage in this order and a straightening stage of the flange part 2 of the aluminum wheel 1 is provided after the casting stage and before machining (cutting) stage. Straightening is performed by using a split piece 12 or a tapered die 12A.
