A hard disk drive with a multiple disk stack normally utilizes disk separator plates near the disk surfaces to reduce wind induced vibrations in the disks and the read/write heads. The manufacturing methods currently used to make these separator plates, metal casting and machining, or injection molded plastic, or extruding and machining, or cold forging tends to be expensive and creates unwanted weight and bulk without the desired precision. Stamping disk separator plates from metal provides exceptional dimensional control at reduced cost, but cannot readily provide the thicknesses required. Stamping and extruding the offsets, or stamping and folding the offsets, is a manufacturing process that provides the required dimensions for the offsets, and dimensional control and reduced cost. |

A cylinder member of an automatic transmission that includes an outer peripheral introducing portion having a shape that is able to be formed by ironing without forming and trimming of a flange portion which was conventionally required for forming an outer peripheral introducing portion. Therefore, steps required for forming the flange portion are omitted, and the number of steps for manufacturing the cylinder member is reduced. Without using a large-scale press machine such as a progressive press and a transfer press, the cylinder member is manufactured by a smaller-sized press machine, thereby reducing equipment investment required for manufacturing the cylinder member. |

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. |

The present invention provides a method for manufacturing a steel plate-shaped component which can increase the yield and the working efficiency. When a steel plate-shaped component (1) such as a pole parking is manufactured, a steel disk-shaped initial material (10) is vertically placed in a cavity (41) of a dice (40) of a cold forging die so that the thickness direction of the initial material (10) is perpendicular to a pressing direction. The initial material (10) is pressed through cold forging against the peripheral side portion (11) by a punch (42) while the initial thickness of the initial material (10) is maintained substantially as it is, whereby an approximate component (20) approximating the plate-shaped component (1) is obtained. Subsequently, a margin portion (25) of the approximate component (20) is removed, whereby a half-finished product (30) is obtained. The half-finished product (30) is subjected to cutting work, carburizing processing, and so on, whereby the plate-shaped component (1) is obtained. |

A method of manufacturing a wear resistant shoe (26) includes upsetting (46) one end portion (38) of cylindrical member to work harden that portion to a substantial depth, machining (48) the cylindrical member portion to finished dimensions and surface hardening (56) a face (28 or 34) of the machined cylindrical member portion. The cylindrical member may comprise rod stock of a diameter less than the greatest diameter of the finished shoe and be upset or swaged to axially reduce and radially increase the dimensions of the one end portion. A hollow region (30) is formed in an opposite rod stock end portion and the periphery (50) of the hollow region is crimped about a rounded end (18) of the piston (20). The cold work done during the swaging or forming process provides a foundation for hardened faces comprising balance (28) and auxiliary balance (34) lands, forms a crude shape of the shoe, and imparts work hardening and wear property improvements. The harder metal surface provides a foundation for subsequent surface hardening such as coating with TiN. The crimping process used to join the shoe to the piston imparts cold work to the skirt region of the shoe and enhances the wear resistance of the shoe. The cold heading step (46) may be omitted if a hardened rod stock is used, but the skirt should be annealed (66) prior to crimping to the piston. |
