Exploiting Sequential-Valve-Gate Molding To Control Weld Lines
ICICTA), 2008 International Conference（2008）
摘要
Weld line is one of the defects occurring in injection molded parts which should be positioned at low-stress and non-critical areas. The paper presents an approach to effectively specify the weld-line locations by exploiting sequential-valve-gate molding. The method accurately repositions the weld lines to the desired locations by varying the opening timings of valve gates and the index of conformity degree between the actual and the desired weld-line locations. An example is used to illustrate the approach.
