Abstract: A semi-solid metal forming process using a cast billet and having the following steps: 1. heating the cast billet to a temperature above its recrystallization temperature and below its solidus temperature; 2. extruding the cast billet into an extruded column; 3. cutting the extruded column into at least one billet; 4. heating the billet from step 3 to a semi-solid state; and 5. squeezing the billet from step 4 into a cavity in a metal forming die set to form a part.

Abstract: A movable insert for a die-casting mold having a cavity in which a core is mounted and slidable between a retracted position in the cavity and an extended position in which the core extends from the movable insert core. The core has a connector releasably connecting the core to a locator. The locator moves the core between the retracted and extended positions.

Abstract: A positioning device for positioning a slidable core in a movable insert of a die casting mold. The positioning device utilizes a rotary actuator coupled to a piston in a hydraulic cylinder to rotate the piston and in turn a cylinder rod. The cylinder rod is provided with a coupling member at an end distal the hydraulic cylinder for releasable coupling with the slidable core for axial movement of the slidable core. An adaptor block mounts the rotary actuator to the hydraulic cylinder. The adaptor block includes a stop for limiting rotation of the rotatable components of the positioning device.
