摘要： A method to manufacture an automobile vehicle engine aluminum piston, comprises: printing an aluminum piston crown portion including an additive manufacturing (AM) piston crown work piece using initial aluminum powders defining an initial aluminum powder bed; removing the aluminum piston crown portion from the initial aluminum powder bed; fixedly joining a cast iron ring carrier to the AM piston crown work piece; placing the aluminum piston crown portion together with the cast iron ring carrier into a secondary and a tertiary aluminum powder bed; and printing a piston skirt integrally connected to the AM piston crown work piece and to the cast iron ring carrier.

摘要： An interlocking tool for a for forming stator end turns includes a first member including a first base having a first surface. A first ring extends from the first surface and a second ring extends from the first surface radially outwardly of the first ring. The second ring is spaced from the first ring by a first gap. A second member includes a second base having a first surface portion. A first ring element extends from the first surface portion and a second ring element extends from the first surface portion radially inwardly of the first ring element. The second ring element is spaced from the first ring element by a second gap. The second ring is positioned in the second gap, and the second ring element is positioned in the first gap. The first member is rotatable relative to the second member.
