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?+ ^8 _, m1 V T' t
在對比零件時(shí)我注意到WWY底部比較厚(0.08,,連側(cè)壁為0.04),,底部內(nèi)部還有一個(gè)凸包,在澆口位置,。這樣就像一個(gè)冷料井,,可能會產(chǎn)生湍流?

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 .

我還注意到WWY小端側(cè)壁有個(gè)臺階,,在小凸點(diǎn)前面的位置,。這個(gè)臺階跟大面垂直,像個(gè)加強(qiáng)筋防止變形,。ABC的剖面變形會醉厲害。* V+ [2 R4 _) \& I
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.
