What will we do for its surface? Texture or Polishing? Does this part need an ejector pin or an ejector bar? Can we add an ejector blade? Can we add ejector sleeves or ejector pins in the boss of this part? There's an undercut at this position and it needs a slider. It will also have a parting line on this side, is that OK? We will make the lifter or innerslider in this position, will that be a problem? 20 21 22 23 24 25 26 我們打算在這個位置做斜頂或內滑塊，有問題嗎？ 你提供的2D產品圖與3D產品圖The 2D and 3D drawing you provided is not the 不一致，請問以哪一個圖正確？ same, can you tell me which one is correct? 你提供的3D產品圖有的地方沒有脫模角，有的地方膠位太厚，有的地方膠位元太薄，這些產品問題我們可以自己修改嗎？修改後會給交給你確認。 按你們提供的縮水率千分之五，這個模具的尺寸已經做到了模具圖面要求。 注塑出來的產品不符合你們的產品圖。請確認你們的材料的縮水率是否正確？ 產品的這個位置太小，導致模具鋼料太薄，能夠加寬這個位置嗎？ There is no draft angle in the 3D drawing, some materials are too thick, and some place are too thin. Can we modify this part by ourselves? We will send the drawing to you for you to check after we modify it. According to the shrinkage one over two hundred, the mold has been done in the right dimension, The part falls short to your part drawing, are you sure the shrinkage is right? This position is too small and will make the steel material here too thin, can we widen it here? 27 28 29 30 斜頂與後面的Boss空間太小，斜The angular lifter interferes with the boss during 頂在運動時會干涉到柱子，能移ejection.

偏高，注塑時很難填充這個筋位，可以增加這個筋骨位的厚度嗎？ 32 你是想將此筋骨位的高度加高/減低嗎？假如加膠,我們將用放電方式加深。 減膠修改有兩種做法， 1、做鑲件； 2、燒焊；因為鑲件的底部有運水，我們簡單的做法是燒焊處理，你可以接受嗎？ 34 這個樣板的筋骨位底部燒焦，是因為排氣不良，我們可以在筋骨位的中間增加一個鑲件。 重做鑲件大約需要5-6天時間 產品的這個面我們已經做了曬紋處理，如果需要加膠，這個面我們需要重新外發曬紋。可能需要幾天的時間。所以我們直接以銅公放電的火花紋取代你要求的紋路，你可以接受嗎？ 37 38 39 模具是用公制/英制的配件？ 需要備用件嗎？ 模具上銘牌上的刻字內容是由你們提供嗎？你們什麼時候可以這些刻字資料。 will be difficult to fill here when we do the injection, can you increase the thickness of this rib? Will you increase/decrease the material on this rib? If add the material,We willmodify it with EDM process There are two option if decrease the material: 1.Make inserts; 2.Welding, because there is water in the bottom of the insert, is that OK? This sample has been burned in the bottom because the venting is not good, we can add an insert in the middle of the rib. It will take about 5 or 6 days to redo the insert We have made the texture on this side, if we add material, it will take some days to remake the texture by out-resourcing, so we suggest using the texture by EDM instead, is that OK? 33 35 36 Is this mold dimension measured in inches or meters? Does it need spare parts? Will you provide the engraving content of the plate of this mold to us?

Please advise where the critical surface is. Please also provide us a 2D drawing with critical dimensions. Please note the red highlights because those areas have problems. We would suggest using the attached part design as the current design has problems. We suggest modifying it as a globe recess. The inside small slide block will recede first and the parent slide block have to postpone sliding. The slide pins will use an oil cylinder to assure that the process is in proper order. We cannot add material to this surface because it will intervene between the two parts when it is assembled. 49 50 51 52 53 54 55 56 57 - -可修编.
