Because of the accuracy of the manufacture, it is difficult to make the slider hole the same level with

7、 the core depth, so we suggest reducing 0.05mm plastic on the ribs, please make the same change to both LH & RH holes.,2 建议前后模大分型线处做段差（后模做小单边0.05mm）We suggest making step on the PL between cavity and core （reduce 0.05MM plastic on single side of core）,3 怕结合力不好，建议第一色做孔，增加结合力. We suggest add some hole

8、s on the first shot in order to increase the adhesion strength,4 为利于模具制作及简化分型面，建议箭头所指侧面减胶拔模到后模. We suggest the by arrow indicated side reduce material and making into the core in order to manufacture the tool easier and simplify the parting line. 5 建议上图中两个绿色孔侧面沿行位运动方向做脱模斜度 We suggest adding draft on

9、 2 green sides along the moving direction of slider. 6 为了保证外观面，建议将PL面下移0.2MM。 Suggest lowering the PL 0.2MM to avoid the PL on the visible surface.,7 此绿色面没有出模角，建议以减胶方式做3度的出模角以便行位出模。 No draft in green area, suggest reducing plastic and draft angle 3degree to release the slider easily. 8 此处掏胶掏进去0.6MM.

10、 Here reduce 0.6mm plastic injection. 9 此处打1圆点或2圆点作为型腔号，请确认！ Make 1dot or 2s as the cavity number 10 产品此两处侧面绿色面为直身面，为防止产品此面脱花或拉伤，需增加出模角度0.5（产品减胶） The green area have no draft angle, to avoid any scratch, we would like to reduce plastic for 0.5 draft angle.,11 后模绿色骨位没有脱模斜度 there is no draft on core r
