20130186162 | MOLD FOR EXTRUDING AN ALUMINUM SEAT OF A HEAT SINK AND A METHOD FOR MAKING THE SAME - An aluminum seat of a heat sink is made by placing a fixed amount of aluminum material into a forming slot of a lower die to undergo one-time extrusion by a punch of an upper die. A plurality of indentations are longitudinally disposed on an interior wall of the forming slot of the lower die, and the bottom of the forming slot is a closed end. When the fixed amount of aluminum material is distributed over the forming slot and the indentations during the extrusion, corresponding ribs are formed on an exterior wall of the aluminum seat of the heat sink after the dies are drawn off. Each rib facilitates firm insertion of fin units into the seat. The heat sink with radial fin units is produced from the aluminum seat and the fin units. | 07-25-2013 |

20090173128 | METHOD OF WELDING HEATED LOG SEGMENTS IN AN ALUMINUM EXTRUSION PROCESS - A method of processing heated metal logs in a metal extrusion process. The remainder of each log is attached to the succeeding log. Specifically, the abutted ends of the two log segments are aligned with a saw. The saw is actuated to simultaneously remove material from both of the abutted ends. The cut ends are friction welded together through relative rotation of the log segments. The process creates a heated log column that is effectively endless, eliminating log remainders. | 07-09-2009 |
