PURPOSE:To prevent deformation and lowering of strength of a molded piece due to fiber orientation by adjusting a thickness of a resin material which flows in a diffusion area so as to minimize the deformation of the molded piece due to the fiber orientation in the resin flowing in a cavity. CONSTITUTION:An analyzing/calculating program is provided in a computer 10. The analyzing/calculating program calculates information for controlling a thickness adjusting pin 4 which changes a thickness of a resin material 1 flowing in a diffusion area 9 ranging from parts just under gates 5 to a plate flow area. By the analyzing/calculating program, the thickness of the resin material at the cavity 6 in the diffusion flow area, which minimizes deformation of a molded piece due to fiber orientation in the resin material 1 flowing in the cavity 6, is obtained. A driving section of the thickness adjusting pin 4 moves the thickness adjusting pin 4 up and down so as to make the thickness of the resin material a required value. |
