4、e area and specifications according to the draft figure and texture specification table. 请确认皮纹区域和指定皮纹角度和能力40. Cosmetic issue 外表面问题55. Stress mark on the cosmetic surface 产品外表面上有压痕59. There is black spot on the cosmetic surface 产品外表面上有黑色点63. There is argent spot 这里有亮点（银色斑点）73. Black paint on back sid
5、e。背面喷黑漆处理。75. Sharp edge shown in red circle, there may occur as flash or burr issue after painting process, it will impact to paint yield rate. 红色圆圈内的棱角在喷漆后有可能产生飞边现象，增加喷漆返工比率79. Location hole for spray painting 喷漆工艺孔。87. Please confirm this surface is non-cosmetic or not? 请确认该面是否有外观要求？88. Do there
6、any Cosmetic surface? 是否有任何外观面要求？95. All the magenta face need to high glossy 所有紫色面需高抛光处理98. Re-polish the electrode and re-do EDM 电极重新抛光和放电103 .We have suggested 2 options based on customer requirement 在客户的基础上我们提供2 种方案。Option 1 will be a better choice we are proposing texture from raw material. 方案
7、1 是更好的建议，在粗加工基础上做皮纹处理。Secondary process is required for option 2 as bending will affect material texture. 方案 2，后加工变形会影响产品皮纹。四, remark/mark 9.Remarks on geometry 表面标记22. Marking of the part 产品标记23.Comments/ open issues 问题点77. Core side no any marks 后模无任何标记五, wall thickness 10. Analysis wall thickness
8、 产品壁厚分析11. Thick section, propose to reduce plastic to keep even wall. 产品厚壁部份，建议减胶以保持均匀壁厚56. Uneven thickness 不平均的产品壁厚69. It is too thin and very difficult to inject fully, and weakness wall will have risk of the part function 该处壁厚过薄而造成很难去填充完整，薄壁将会有产品功能上的风险。70. These are will have sink marks due to
9、uneven thickness, propose to reduce plastic. 壁厚不均匀容易产生缩印，建议在该处减胶。72 . Please confirm the 3D part thickness whether has including painting thickness or not? 请确认产品的设计是否考虑到油漆的厚度. 74. Average wall thickness is 0.50 only, Max is 0.74. It is too thin and very difficult to inject fully. 产品均厚仅有0.5mm，最厚为 0.7

Numbers of venting insert on core is necessary to exhaust the air from inside to outside. 该薄壁件壁厚仅为0.5mm，建议使用高压注塑机成型。在后模侧的一定数量的排气镶件利于成型。83.
11、ropose to reduce plastic form 1.02mm to 0.9mm as right picture shown to avoid sticking cavity side. 右图示的区域建议减胶从1.2mm 到 0.9mm，以避免前模粘模。六, sink marks 50. High shrinkage values could indicate sink marks or voids at gate location 高缩水率的产品容易产生缩印，但在浇口附近可以避免61. there is sink mark on the cosmetic surface 产品外表
12、面上有缩痕71. These are will have sink marks due to ribs opposite. 正面的筋位易导致背面产生缩印。104. Sink mark will occur on yellow region. Because of thickness vibration, it is no use to increase gate size. 由于壁厚的震动导致黄色区域会有缩印，没有必要增加浇口尺寸。106 . Please keep intend on sink mark problem 请关注缩印问题。110. The gusset is too thick
