  • Predicting shrinkage of injection molded products with viscoelastic characteristic
    Patent number: 8768662
    Abstract: A computer-implemented method and non-transitory computer medium for calculating a shrinkage of a molding product comprises a step of using a computer processor to calculate a molding pressure of a molding fluid in a molding cavity by taking into consideration an increase of a shear viscosity of the molding fluid by a decrease of a shear rate, and a step of calculating the shrinkage of the molding products by taking into consideration a variation of a specific volume of the molding fluid as the molding pressure and a molding temperature decrease.
    Type: Grant
    Filed: November 27, 2013
    Date of Patent: July 1, 2014
    Assignee: Coretech System Co., Ltd.
    Inventors: Rong Yeu Chang, Chia Hsiang Hsu, Hsien Sen Chiu, Shih Po Sun, Chen Chieh Wang, Huan Chang Tseng
