Measures to control the occurrence of weld lines in injection molding for appearance defects.
Automatically explores gate positions that do not result in appearance defects in collaboration with 3D TIMON.
Weld lines can become an issue of strength and design depending on their occurrence location. To control the occurrence location of weld lines, it is generally known that changing the gate position, resin temperature, mold temperature, and holding pressure can be effective. In this case, we optimized the gate position to prevent weld lines from occurring in specified locations by integrating the general-purpose parameter optimization software "AMDESS" with the plastic injection molding CAE software "3D TIMON" developed by Toray Engineering Co., Ltd. As a result, by changing the gate position, we were able to shift the weld lines away from the specified area. [Results] - By changing the gate position, we were able to shift the weld lines away from the specified area. - The approximation of the objective function improved with each addition of the approximation accuracy enhancement proposal. - The effectiveness of the approximation accuracy enhancement proposals was also confirmed. *For more details, please refer to the PDF document or feel free to contact us.
