（十一）: selection:

           射咀 头部 is 球面, its large small need and mold type versus combined, generally lower, 射咀 球面 semi small mold semi 径0.5-1mm.

（十二）: amount adjustment:

           amount is 需数次调校, generally is made formed product and water weight, again add upper coarse 略估计 holding pressure amount.

（十三）: amount adjustment:

           amount large 于实际射胶 amount, products easy generate unstable and sink marks phenomenon.

（十四）: cooling water adjustment:

            1）: mold cooling 不当, effect/influence products quality and formed demolding difficult, attention/notes adjustment water amount large small.

            2）: 熔胶筒尾部 cooling water maintain and low temperature, anti in material 口处熔化, formed lower material difficult.

            3）: pressure temperature maintain in 30至50 degree between.

七: injection molding machine repair as process/workflow:

（一）: repair 时 需 工 tool:

            1）: use table/sheet （ requirements tool has temperature degree testing function ）.

            2）: inner 六角扳手一 sleeve/set.

            3）: active 动扳手6寸, 8寸, 12寸.

            6）: electrical iron （220V-50W）.

（二）: repair in must attention/notes safety 事项:

1）: in equipment as 时, can is 方便, solid 定挡门.

            2）: fault/failure repair 时, need lower 急停开关, necessary 时切断 electrical 源

    开关.

3）: 当手需进入动模处, must safety 门. has necessary machine, ensure

safety.

4）: 当身体进入动 clamping between as 业时, must front 停止马达, lower 急

停 made.

            5）: 当接触射咀时, need belt/tape good 保护手 sleeve/set, attention/notes need 靠近射咀.

            6）: repair hot 圈时, need add hot electrical hot, anti electrical.

            7）: in repair as front, need electrical 源总开关时, need in 总开关处放置“ prohibited combined 闸“牌.

            8）: in repair electrical appliances system in, need attention/notes has short 路, 断路, type 接线, 接 螺 filament has 否松动,

（三）: repair formed rear precautions:

            1）: repair rear need use tool 归放回原处, need in machine upper.

            2）: repair rear will machine 恢复原状, 并清理现场, ensure machine 周围 清洁.

            3）: will machine electrical 并实际操 as 数次, machine as positive rear 才离开.

            4）: detailed good fault/failure phenomenon 记录.
