Method of manufacturing refrigerant compressor

摘要: PROBLEM TO BE SOLVED: To reduce a cost and to waste material while assuring reliability of sliding member in refrigerant compressor. SOLUTION: The compressor includes unit 4 having flat plate 7a thin protruding part 7c from the perpendicular direction, motor 3 for driving 4. A method manufacturing heating cast iron raw until becoming half-melting state slurry, pressurizing this slurry mold, then air cooling molding by thixocasting process performing normalizing treatment, ultraprecision finishing surface corresponding member, thereby 7.
