METHOD FOR DETERMINING MOLDING CONDITION

WIPO Patent Application WO/2010/010922

A1

Provided is a method for determining the molding conditions of a press, which can reduce the cost. A method for determining the molding conditions of a press comprises a step for determining a minimum wrinkle reducing power which may cause cracking while fixing the wrinkle reducing power from start to finish of molding, a step for calculating the average value of reference wrinkle reducing power P3, which is lower than the wrinkle reducing power thus determined, from start to finish of molding, and a step for extracting a variation pattern t5 of wrinkle reducing power which can prevent occurrence of both wrinkle and cracking among variation patterns t1-t5 of wrinkle reducing power where the calculated average value P3 becomes constant.
