Abstract

PURPOSE:To manufacture a primary radiator of light weight and having mass- productivity inexpensively, by forming a cylindrical, conical or circular metallic plate incorporatedly in matching with a metallic die with plastic forming. CONSTITUTION:A material 11 formed by a thin plate having ductility bonded cylindrically or conically, or a discoid material is formed. The material 11 is closingly fixed to the metallic die 12 having an outer diameter processed the same size as the inner diameter of the primary radiator and rotated by rotating devices 13 and 14. Succeedingly, the material 11 is made to plastic forming with a roller 15 or a pallet in matching the material with the die 12. In this plastic forming method, the thinner material and that having better ductility are manufactured more accurately and the light weight is attained at the same time. The primary radiator is obtained by mounting a flange 17 to the product 16.
