摘要： Compressor shoe is manufactured by cutting a wire into cut pieces each having a volume approximately equivalent to that of a desired shoe. The cut piece is sequentially forged with forging dies having three cavities. The cut piece is first forged to a cylindrical shape with a small rounded portion, then to a rugby ball shape, and then to a shape corresponding to a shoe shape. A finishing step, including heat treatment, is then carried out to obtain a compressor shoe.
