Z direction deflection The plots are the deflection of Z component by scaled up 10 times. Conclusion: There has obvious hesitance on the meshes area; (See page 7) The injection pressure is a little high, but it can be accepted; There has low temperature on the meshes area because of hesitance; (See page 9) There has no sink marks on part surface; Pay attention to the weld lines and air traps; (See page 10,11) The part deflection is small. Suggestion: The gate location is feasible. In order to avoid hesitance, we suggest to increase the thickness of the red surface from 1.5mm to 2.0mm. (See next page) 1.5mm There has no hesitance on the meshes area after increasing the thickness. (Full screen to see animation) 我處現有之台中精機及三菱機型﹐其KO孔位置及規格如右圖所示。其設計定位環尺寸為100mm﹐射嘴SR21mm OK No texture?
