injection molding machine machine temperature degree control is utilizing micro machine control 回路, selection combined control method formed for injection machine machine outer add hot sleeve/set control. ensure machine inner 各段 工 as temperature degree can according to process upper requirements maintain in setting scope/range inner, temperature degree control in precision injection molding upper has improve/increase product quality and Raw Materials utilizing rate, is 一项十 separation important indicators.

injection molding machine material temperature degree control for is non property, 不确定, strong/high combined and large rear system, is its in control difficulty/challenge. for/regarding this category of for 象, currently also 缺乏一 统一 has control methods, PID control methods method meet/satisfy high degree injection requirements.

injection molding machine production different product, amount different, ring temperature degree different, production cycle meanwhile its material temperature degree for type parameters 就不一样; material 桶各段 temperature degree control between in very strong/high combined phenomenon, need achieve full understanding control non difficult; another for also is large rear system, control methods difficult 免会出现 large ultra- 调 and phenomenon, therefore must research 自适应 temperature degree control achieve high degree temperature degree control.

in plastics processing process in, temperature degree control main/primary material 筒, nozzle and mold temperature degree control. material temperature degree material surface add hot temperature degree, due to material 筒 壁 comparison thick, therefore, hot electrical testing selection non key/critical, different testing upper temperature degree has relatively large 差异. therefore di 点平行 testing, in material surface and deep meanwhile hot electrical 偶, will to comparison stability temperature degree 曲线, has temperature degree control degree.

nozzle temperature degree effect/influence melt through 时 剪切 flow, for products quality has large effect/influence, therefore nozzle temperature degree control degree requirements more high. mold temperature degree is and products mold cavity surface temperature degree, it significantly effect/influence 充模, cooling and holding pressure process.
