PROBLEM TO BE SOLVED: To provide a casting mold that solves problems of efficient cooling and back frame mounting, to be more concrete, various problems such as machining loss of copper or copper alloy material, a great deal of machining time, improvement of joining position accuracy and of joining strength reliability of a stud bolt, and thermal deformation and thermal deterioration of copper material. SOLUTION: The manufacturing method for different kinds of metallic members includes a first process in which a different kind of metallic member in high-speed revolution is brought into pressurized contact with a stationary casting mold composed of copper or copper alloy, a second process in which the different kind of metallic member is stopped, and a third process in which a thrusting pressure larger than the pressure in the first process is imparted to the casting mold. This casting mold is made by joining different kinds of metallic members. COPYRIGHT: (C)2005,JPO&NCIPI |
