1、产品1：这个产品还有一件镜像体，这里不重复分析。70.672.64Part 1: RH and LH is mirrored so only one of it is shown in this report.注意，本文件底色绿色部分的翻译文本为比较合适的表述效果。镶针深入0.10MM封胶，避免出披锋。To avoid occur flash ,suggest to let insert go deep into seal off surface 0.01mm Suggest to create a 0.1mm concave at core (cavity) steel for the pi

2、n insert seal off in order to optimize/improve the flash direction, if any.Improve: 改善Optimize：优化Tuning：调整,if any: 如果有的话In case0.1MM前后模镶针碰穿，避免出现段差，前模镶针比后模镶针做大0.1MM.Due to core insert pin shutting off,suggest to make the size of cavity insert pin biger 0.1mm than core insert pin size to avoid occur l

3、ever markThere is shutoff between core pins, we suggest to make cavity side core pin 0.1mm bigger.如图，红色部分出前模，产品减胶0.05MMIndicated red surface for cavity,suggest to remove material 0.05mm分型面与骨位底面平行PL surface be parallel to the bottom surface of ribThe surfaces in red is formed by the cavity which need

4、 to create positive draft by removing material, max. 0.05mmPositive：正面的Negative: 负面的Draft: 出模角MMC: Maximum Material ConditionParting line will be in parallel to the bottom surface this rib.所指红色面直身，建议往前模加胶拨模2度，最大加胶0.06MM详见修改后的产品3D所指红色面倒扣，建议往前模拨模0.3度，最大加胶0.19MM详见修改后的产品3D所指红色面倒扣，建议往前模加胶拨模2度，最大减胶0.13MM详

5、见修改后的产品3DIndicated red surface without draft angle,suggest to apply 2 degree at the cavity side,max. material added is 0.06mm,more details refer to modified part 3DIndicated red surface is undercut, suggest to apply 0.3 degree at the cavity side by adding material,max. material added is 0.19mm,more

6、details refer to modified part 3DIndicated red surface is undercut, suggest to apply 2 degree at the cavity side by removing material,max. material removal is 0.19mm,more details refer to modified part 3DThere is no draft in the red surfaces, suggest to apply 2 degree in cavity direction by adding m

7、aterial, max. material added is 0.06mm, please refer to part 3D data updated/modified by us.Update: 升级Modify: 更改Latest=updated: 最新Undercut in red surface as indicated.所指红色面倒扣，建议往行位减胶拨模2度，最大减胶0.05MM详见修改后的产品3D为避免行位薄钢建议所指红色面加胶到行位分型面，最大加胶0.09MM详见修改后的产品3D为避免行位薄钢建议所指红色面加胶到行位分型面，最大加胶0.05MM详见修改后的产品3DSuggest

8、 to add material into parallel with PL to avoid slide too thin, max. material added is 0.09mm,more details refer to modified part 3DIndicated red surface is undercut, suggest to apply 2 degree at the cavity side by removing material,max. material removal is 0.05mm,more details refer to modified part

9、 3DSuggest to add material into parallel with PL to avoid slide too thin, max. material added is 0.05mm,more details refer to modified part 3DThin steel condition in slide at red surfaces, suggest to increase material to level up the surface to parting line, max. material added is 0.09mm, please ref

10、er to the updated data for your approval.Level upFor your approval.6.1The insert is too small,whick is no space to make water-line,so we propose to apply the material is made of BeCu.后模镶件太小，运水无法到达胶位上面This insert is too small to apply water line, we suggest to apply BeCu for better cooling.0.5修改前修改后0

11、.522第2色It is only 0.5mm steel to sealing-off that is too thin，propose to increase another 1.5mm minimum ( the red surface) as indicated, Then the steel thickness becomes 2mm for sealing.2nd shotBeforeAfter如图示第二色红色面处出行位（如下图）封胶面出现薄钢（0.5mm）影响第二色行位封胶钢料强度，建议此处红色面处减胶由0.5mm变更至2mm，OK? There is 0.5mm steel f

12、or seal-off which is too thin, propose to increase 1.5mm min.as indicated in red, so that the steel thickness becomes 2mm for seal off.To avoid getting part surface scrached when the slide returns back during the 2nd shot and increase the slide shrengh,suggest to apply 3 degree by removing material

13、0.3mm in red surface slide direction.Indicated green surface without angle draft in slide direction 为避免第二色行位成型复位插烧坏产品及增加行位强度，建议如图所指红色面延行位出模方向做3减胶0.3拔模，OK?如图绿色面为出行位方向直升面To avoid red surface being scratched during the slide travelling, suggest to apply 3 degree draft at slide movement direction by rem

14、oving material, max. removal is 0.3mm, which is also better for slide seal off to avoid galling.Slide movement directionTravellingRemoval: 去除量Galling: 磨伤如右图示按粉色面延伸下去，延伸面会与红色面有0.04间距，为便于行位分型加工，建议红色面替平粉色面，OK?JL7B-19K617-A-PIA-6B Slider Knob Substrate w Overmold Rev 0产品问题点一样SlideIndicated pink surface

15、,extend surface will occur 0.04mm distance between with red surface,suggest to changed the red surface be parallel to pink surface,the same as JL7B-19K617-A-PIA-6B Slider Knob Substrate w Overmold Rev 0The pink surface is 0.04mm off the plan for red surface, suggest to level up the pink surface in o

16、rder to simplify the machining.如图示红色面出前模倒扣（另一侧一样），建议红色面延前模出模方向做3减胶0.08mm拔模，OK?JL7B-19K617-A-PIA-6B Slider Knob Substrate w Overmold Rev 0产品问题点一样Indicated red surface is undercut(the same as other side),suggset to apply 3 degree by removing material 0.08mm in red surface extend direction,the same as JL7B-19K617-A-PIA-6B Slider Knob Substrate w Overmold Rev 0 设计师要求：不同问题点用不同颜色，放大图片必须与全景图片相同颜色、相同角度。如图示产品大面处间距只有0.014mm，为便于加工，产品此面能否修该成一致,OK?0.014JL7B-19K617-A-PIA-6B Slider Knob Substrate w Overmold Re
