和滑塊干涉的倒勾請加膠填平至45 The undercut area interferes with the slide 滑塊可以順利滑動 block and needs to be filled with material to help the slider move smoothly.

此面是否有特殊要求,能否有頂46 Please confirm whether it is a

critical surface 針痕 or not and if we can have E.J. pin marks on it.

此處Gate做潛伏市灌頂針的47 If the design of the gate has to be a sub. 話,背後的外觀面會有沖料Gate, then the back surface of the part

will 痕,而且成品又是黑色的,會have serious flow marks due to the black 最明顯 color.

P.L開在此處不合理,模具加工困48 This area is not suitable to have a Parting line 難,P.L應改為和圖示的一樣 because the tool will become more complicated; therefore,

we recommend to have the Parting line as

indicated.

產品粘母模的機會很大,能否在49 There is possible sticking on cavity; therefore, 公模加倒勾,拉料頂針或者公模please confirm whether it can make 保留E.D.M紋,開模時使成品留undercuts, snatch pins

在公模一側 or leave coarse E.D.M. on the core to snatch

此處料厚段差很大,成品表面會50 Please confirm whether it is acceptable to 有應力痕,是否接受 have stress lines on the surface because the

thickness is not equal.

請注明何處為外觀面,能否提供51 Please advise where the critical surface is. 2D圖和注意事項 Please also provide us a 2D drawing with critical dimensions.

紅色所示處是有問題的地方,請52 Please note the red highlights because those

特別注意 areas have problems.

成品設計此處有問題,建議如下53 We would suggest using the attached part 圖所示修改 design as the current design has problems.

此處改為一個球形的凹槽 54 We suggest modifying it as a globe recess.

此處大滑塊上走小滑塊,小滑塊55 The inside small slide block will recede first

要先退,大滑塊要做延遲 and the parent slide block have to postpone sliding.

滑塊要用液壓油缸抽芯以保証開56 The slide pins will use an oil cylinder to assure 合模順序 that the process is in proper order.

這個面有裝配,加料的話裝配時57 We cannot add material to this surface 會頂住,如圖所示 because it will intervene between the two parts when it is assembled.

Please see the sketch attached.

可降低斜銷面,增加成品些許肉58 To descend the surface of lifter in order to 厚來做變化 thicken the part.

一半做斜銷,一半做自然 59 One half side will have the lifter and the other

half will be solid/nature.

此處兩個柱子重疊,有倒勾,不60 These two bosses are overlapping with 能做自然,要做SLIDE undercut therefore it can not be made as solid. We

suggest making it with a slide block.

此處強迫頂出 61 This area needs force ejection.

公模兩段開模,這個地方先退 62 Here will be a double ejection for forward and

receding.

此處做鑲件會有夾線,能否接受 63 Please confirm whether it is acceptable that

there will be a split line here.

此面公母模1度靠破,會有段64 Please confirm whether it is ok to have 差,可否接受 mismatch to the area where there is 1 degree of shut off in Core / Cavity side.

這個尺寸能否加大 65 Please confirm whether we can enlarge this

dimension.

此處加一個凹槽,膠片的彈出效66 It will affect the elastic of the film better if we 果會更好一些,試模後看裝配的add a recess. See how it will affect the 效果再做修正 assembly parts,

and then make your decision.

此處有倒勾,建議將剖面線所示67 There is an undercut here, we suggest cutting 部位CUT即可避免此處的倒勾 out the indicated part as it highlighted to

avoid an undercut.

成型後SUB GATE要修平 68 The gate (sub gate) needs to be trimmed evenly after being moulded.

此處倒勾先垂直頂出,之後再手69 This area of the undercut needs to be ejected 動取出 vertically, then taken out manually.

這兩個面都有滑塊,GATE改在70 The gate is not suitable in this area becuase 此處改不到 there are two sliding blocks sealing off this area.

此處加做一個旋轉GATE,射出71 We would suggest placing a runner shut-off

時方便調整成品的品質 insert to adjust the volume of part filling.

此倒勾在滑塊上強迫脫模,倒勾72 This undercut will be force ejected out, Please 是否可以減小到0.6 confirm whether it can be reduced to 0.6 mm.

此柱子無法脫模,請確認是否是73 This boss is not releasable. Please check the 在轉圖時錯位,能否提供客戶的file again and if possible, pleas re-send us the

原始圖檔 data. original draft.

此柱子是實心的,會縮水 74 This boss will shrink because it is a solid boss.

這個面是否要咬花,咬花番號是75 Please confirm whether this surface needs to 什麼,最小的拔模角要多大 be textured or not. Please advise texture

specs. Also, what's the min. draft.

這個面是否要打光,貼標簽 76 Please confirm whether this surface needs to

be polished and stuck on a sticker.

紅色顯示的幾個面拔模角太小,77 The red highlighted area has a problem of a 出模時會拉傷,建議加大拔模角 small draft angle. We suggest enlarging the

draft to avoid casuing drag marks on the part.

此RIB太薄,會填充不足 78 This rib can not be filled properly because it is

too thin.

此RIB太厚,會縮水 79 This rib will have a shrink problem because it is too thick.

此處倒勾出模困難,建議先不做80 There are problems with this current design, 倒勾,成型後再二次加工,但要we recommend doing this undercut as an 做治具,費用要另外算 alternative but there will be additional costs.

柱子底部都要做火山口 81 The base of all bosses require a crater to avoid shrinkage.

鑲件,P.L.面有充足排氣坑,P.L.82 Insert/PL should have adequate venting,PL 面要開環形排氣槽,並能將氣體should have around slot for venting.
