Abstract
A process for manufacturing an aluminum alloy wheel includes: casting, de-flashing, soaking, spinning, thermal treatment, de-gating, X-ray and machining. During the casting, a casting mold is cooled with water, and a cast blank is produced from carrying out the casting. The de-flashing includes removing flashes of the cast blank at a rim of the cast blank with a de-flashing device. The soaking includes reheating on the cast blank that has been de-flashed. The spinning includes an adaptive spinning mold. The thermal treatment includes direct solution treatment and aging on the cast blank in a thermal treatment furnace after spinning.
