In comparing the parts I have noticed that the WWY part has a thicker bottom section (around0.080/connecting side wall 0.040). There is also a small cup on the inside of their bottom,where it's gated, that is working like a cold slug well . This is probably something to create turbulent flow?. J J/ A9 B }4 B9 V# s
在对比零件时我注意到WWY底部比较厚(0.08,连侧壁为0.04),底部内部还有一个凸包,在浇口位置。这样就像一个冷料井,可能会产生湍流?. }; I/ c. b) r0 K3 D! j7 b( ^
In molding you should inject thick to thin wall to minimize pressure drop and be able to pack out the thicker section. Would it be possible for ABC to thicken the bottom of their part and add something like this small cup to funtion as a cold slug well.
; K2 N3 H5 v& M注塑的时候需要先注厚的再到薄的地方来减少注塑压力下降又能够先打满厚的部位。是否可能在ABC底部加厚或者加个小凸包,做个冷料井?0 S# E; Y$ `, _) U, }( b
I also notice that the WWY part has a step in the lower side wall just before the small nipple . This step ,being perpendicular to the main wall, is working as a strength rib and is helping to prevent the wall from bulging out . The section on ABC part appears to warp the most .

I will need to get from you , the sprue size , runner size and design, as well as gate size , if we are to have a mold flow analysis done on your part.
