Abstract: A method and apparatus for the lost pattern casting of metals employs an erodable mold including a particulate material and a binder. An erodable backing or coating may be used to support the erodable mold. After a molten metal casting is poured in the mold, the erodable backing and the mold are contacted with a solvent. This cools the molten metal so that it at least partially solidifies to form a casting. At least a part of the mold is removed. Also, the coating or backing may be removed.

Abstract: A method for manufacturing a vehicle wheel includes the steps of providing a wheel rim and a spider and holding the spider inside the wheel rim. The wheel rim and the spider are positioned in a high capacity forming machine. At least one of a portion of the wheel rim located adjacent an outer periphery of the spider and a portion of the outer periphery of the spider is permanently deformed towards the other of the wheel rim and the spider thereby securing the wheel rim to the spider. An apparatus for securing the wheel rim to the spider includes a bottom die, a bottom inside rim stabilizer supported on the bottom die, a spider supported on the bottom inside rim stabilizer, a top inside rim stabilizer and a wheel rim supported by the bottom rim stabilizer and the top inside rim stabilizer. A high capacity forming machine encircles the wheel rim. The high capacity forming machine includes a workpiece which at least sometimes contacts the wheel rim and an electric circuit located adjacent the workpiece. A capacitor bank is electrically connected to the electric circuit of the high capacity forming machine. A switching circuit is electrically connected between the capacitor bank and the electric circuit for regulating a discharge of electricity from the capacitor bank into the circuit. The workpiece of the high capacity forming machine is capable of delivering a forming velocity of at least 10 m/second. A typical workpiece is either a resilient wall of an electrohydraulic device or a compression coil of an electromagnetic device.

Abstract: A method for manufacturing a vehicle wheel includes the steps of providing a wheel rim and a spider and positioning the wheel rim and the spider adjacent each other. The wheel rim and the spider are then friction welded to each other. Subsequently, a portion of the spider is locked down onto the wheel rim by electromagnetic forming. Preferably, one end of the rim is positioned in a cavity formed in the spider. During friction welding, the upset material of the rim fills the cavity of the spider. Subsequently, while the metal is still relatively fluid, a flange of the spider is locked down onto the wheel rim by electromagnetic forming to secure the wheel rim and spider together.
