Patent ID: 8490278

Claim:
A manufacturing method of a magnesium alloy press-formed body, comprising: coating an organic resin capable of imparting formability onto a surface of a magnesium alloy material; press-forming the organic resin-coated magnesium alloy material at a temperature of 200-350 ° C. into a desired shape under conditions whereby the magnesium alloy material subjected to said press-forming exhibits a friction coefficient of 0.2 or less at said press-forming temperature, and removing the organic resin from the organic resin-coated magnesium alloy materialby immersing in a resin removing liquid which includes an alkaline aqueous solution having pH of 10 or more; wherein the organic resin comprises one, two or more resins selected from the group consisting of a water-soluble urethane resin, a water-soluble polyester resin, a water-soluble acrylic resin, a water-soluble epoxy resin, and a resin produced by modification of any one of said organic resins.
