temperature, pressure, speed, this injection molding process how 调?

         temperature degree

         temperature degree amount and control in injection molding in is separation important. although this amount is versus for simple, more injection molding machine has temperature degree or 线路.

         in more injection molding 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;越 is add hot, 讯号越 strong/high.

         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.

        熔胶 temperature degree

        熔胶 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 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 front, ensure liquid pressure 油, material 斗封闭 device, mold and material 缸都处于 positive temperature degree lower.

         injection molding pressure

         this is plastics flow pressure, can use in or liquid pressure upper device amount. it has solid 定 数 value, mold filling difficult, injection molding pressure increase large, injection molding pressure and injection molding pressure is has 直接关系.

        第一 stage/phase pressure and stage/phase pressure

         in injection molding cycle filling stage/phase in, can can need using/adopting high pressure, 以维持 injection molding speed degree requirements water 平. mold filling rear again need high pressure. in injection molding 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.

        锁模 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 投影面积, is from clamping force application direction to most large 面积.

         for large more injection molding 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 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 machine force;故 back pressure low good, in 任何情况 lower can ultra- injection molding machine injection molding pressure (most high 定额) 20%.

        射嘴 pressure

        射嘴 pressure is 射嘴里面 pressure. it large is plastics flow pressure. it has solid 定 数 value, is mold filling difficult degree add large increase high. pressure, pressure and injection pressure between has 直接 关系.

        射嘴 pressure large ratio injection pressure less large separation left right. in active injection molding machine pressure loss can to separation left right. in active injection molding machine pressure loss can to separation 之五十.

         injection molding speed degree

         this is screw as is 冲头时, mold filling speed degree. injection molding thin products 时, must using/adopting high speed, 以便于熔胶未凝 solid full filling 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.

        无论 using/adopting that type of injection speed degree, must will speed degree value injection time 记录于记录 table/sheet upper, injection time mold to 预定 首 stage/phase pressure must time, is screw time separation.
