　 injection molding processing is types industrial product production type methods. product usually use injection molding and plastics injection molding . injection molding also can separation injection molding pressure method. and pressure method. injection molding machine (简称 injection machine or injection molding machine) is will thermoplastic property plastics or hot solid property material utilizing plastics molding mold made formed various plastics products main/primary molding equipment, injection molding is through injection molding machine and mold achieve.

　　行程 control 也叫位置 control, it is process in, in screw front 进 行程 in 设置若 dry 特殊位置点, this will 射胶行程 separation formed dry 段, using/adopting different pressure, speed degree control 射胶.

　　说明:
　　1, ① is 抽胶终点位置;② is 熔胶终点位置;③ is grade and grade 射胶切换位置;④ is grade and grade 射胶切换位置, to N grade;⑤ is N射胶 and holding pressure 切换位置;⑥ is grade holding pressure and grade holding pressure 切换位置, to N grade;⑦ is holding pressure 终点位置;⑧ screw 原点位置. ⑦ and ⑧ between is 残余胶 amount, ⑧位置残余胶 amount is 0.

　　2, in 射胶段, 每段都会按 setting pressure, speed degree action as; in holding pressure 段, 每段都按 setting holding pressure pressure, holding pressure time holding pressure as. holding pressure holding pressure speed degree generally comparison low, has injection molding machine can holding pressure speed degree setting, has injection molding machine is anti 止不熟练者误操 as, in machine internal good, as can holding pressure speed degree 设置.

　　3, if setting time short, in setting time use rear, screw to 何位置, screw as 终止. therefore, setting time need setting 足够, can ensure setting 射胶, holding pressure as 如期进行.

　　4, 实际射胶 time and as setting injection molding parameters has 关, 会自动计算并显示. setting time large 于实际射胶 time 时, setting time decrease 实际射胶 use rear, its time is holding pressure. holding pressure time excellent separation to grade holding pressure use, grade holding pressure use time again separation to grade holding pressure use, 依次例推, has time full separation to most rear grade, most rear grade holding pressure is use setting holding pressure time. if time 不够, holding pressure to grade time use 完即止, its holding pressure 设置都不起 function.

　　5, 射胶行程 设置应该 is from large to small, 射胶开始位置即 is 熔胶终点位置, has 抽胶(or 倒索)则 is 抽胶终点位置, machine 会自动记忆并设置 is 起点位置, as is 不需输入起点位置. as 者输入 第一 行程位置即 is grade 射胶完 formed 位置(也 is grade 射胶开始位置), grade pressure, speed degree control from 熔胶终点(or 抽胶终点)位置 to 射胶行程第一 输入位置 between as. if as 者输入 行程 parameters 错误, will rear 面 行程 parameters setting ratio front large, machine 会忽略, 自动进入 to lower grade 射胶. ratio 如熔胶终点 is 60, grade 射胶行程 is 50, grade 射胶行程 is 55, grade 射胶行程 is 30, machine in formed grade rear, 忽略二 grade 射胶, 直接进入 to grade 射胶, grade 射胶设置 parameters function. although 如此, as 者需明白 parameters 设置 意义, can will rear 面 行程 parameters ratio front also large.

　　6, control is screw 实际位置 achieve pressure, speed degree 转换, if screw can to setting 位置, 则设置 pressure, speed degree parameters function. also is upper 面 例子, if screw front to 52时 already 经射满胶, screw method again front 行, rear has 设置都不起 function, machine 会以一 grade pressure, speed degree, setting time 进行射胶, holding pressure as, to time use is 止.

　　7, 实际射胶 time, screw machine 会显示, as 者眼睛需盯紧 this parameters, understanding screw 实际动 as 情况并 for parameters 即时修 positive.

　　 time control:

　　 time control versus for control need simple more, 即射胶动 as and screw 行程位置 related 联, full use time control. in setting time inner, setting pressure, speed degree 进行射胶, holding pressure as, to setting time use 完转入 lower grade.

　　 therefore, machine setting time, pressure, speed degree 进行射胶动 as. setting time, pressure 会实实 in in 执行, if already 经射满胶 screw can as, speed degree 就不会以 setting value 进行.
