• temperature degree control hot electrical 偶也广泛应 used as temperature degree control system device. in control device upper, setting need temperature degree, 而感应 device will and setting upper generate temperature degree versus comparison. in this most simple system in, temperature degree to setting 点时, 就会关闭, temperature degree decline rear electrical also heavy new 开启. this type of system is control, is it is is 关. • temperature degree temperature degree amount and control in injection molding parts in is separation important. although this amount is versus for simple, more injection molding parts machine has temperature degree or 线路. in more injection molding parts machine upper, temperature degree is hot electrical 偶感应. hot electrical basic upper strip/profile different electrical 线尾部 versus 接而组 formed. if ratio 另一端 hot, will generate micro small electrical 讯; is add hot, 讯号越 strong/high. • temperature degree temperature degree is very important, use material temperature degree is property. temperature degree can in 射嘴处 amount degree or use gas method amount degree. material temperature degree setting 取决于熔胶 temperature degree, screw speed, back pressure, material amount and injection molding parts cycle. if has processing certain 一特定 grade plastics experience, from most low setting 开始. is control, material separation 区, is has setting is same temperature degree. if as time long or in high temperature lower as, will 第一区 temperature degree setting is relatively low value, this will anti plastics 早熔化 and separation 流. injection molding parts front, ensure liquid pressure 油, material 斗封闭 device, injection molding parts mold and material 缸都处于 positive temperature degree lower. • injection molding parts pressure this is plastics flow pressure, can use in or liquid pressure upper device amount. it has solid 定 数 value, injection molding parts mold filling difficult, injection molding parts pressure increase large, injection molding parts pressure and injection molding parts pressure is has 直接关系. • stage/phase pressure and stage/phase pressure in injection molding parts cycle filling stage/phase in, can can need using/adopting high pressure, 以维持 injection molding parts speed degree requirements water 平. injection molding parts mold filling rear again need high pressure. in injection molding parts semi crystallization property thermoplastic property plastics （如PA and POM）时, due to pressure 骤变, make structure 恶化, therefore has must use stage/phase pressure. • pressure is for resistant injection pressure, must use pressure, need selection can use most large value, need 考虑投影面积, 计算一 适 combined value. injection molding parts parts 投影面积, is from clamping force application direction to most large 面积. for large more injection molding parts 情况 说, it is 每平方英寸2吨, or 每平方米31兆牛顿. however this is low value, but also as is very coarse experience value, is, injection molding parts parts has deep degree, that 么侧壁便必 must 考虑. • back pressure this is screw rear front must need generate and ultra- 越 pressure, using/adopting high back pressure has color material dispersion uniform and plastics 熔化, meanwhile long in screw time, decrease low filling plastics fiber long degree, increase injection molding parts machine force; back pressure low good, in 任何情况 lower can ultra- injection molding parts machine injection molding parts pressure （ most high 定额） 20%. • injection molding parts speed degree this is screw as is 冲头时, injection molding parts mold filling speed degree. injection molding parts thin products 时, must using/adopting high speed, 以便于熔胶未凝 solid full filling injection molding parts mold, production relatively is light slip surface. filling use series 程序化 射 speed, generate or gas and other defect. injection can in ring or ring control system lower 进行. • pressure pressure is 射嘴里面 pressure. it large is plastics flow pressure. it has solid 定 数 value, is injection molding parts mold filling difficult degree add large increase high. pressure, pressure and injection pressure between has 直接 关系. in 螺旋式 injection molding parts machine upper, pressure large ratio injection pressure less large separation left right. in active injection molding parts machine pressure loss can to separation left right. in active injection molding parts machine pressure loss can to separation 之五十.
