         due to injection shot pressure mold to pressure function mold how much 会膨胀一点, if is in mold 恢原状,但 is upper mold inner pressure still maintain high lower make products cooling solid 化, mold in 恢复原状时 use very large force as used for mold, make mold 不 不开启一点. mold viscous 滞弯折 is how 回事呢?

         mold viscous 滞弯折 can can large factors 导致而 formed:

        1, mold rigid property 不足;

        2, due to injection shot pressure mold 膨胀鼓起.

         solution methods:

        即时: for injection shot pressure tube/pipe 理,不 need upper rise to setting value above. long 期:设置凹槽, strong/high made adjustment. for mold mold trial easy 发生, in mold upper add upper per mille table/sheet,一边监视一边 slow rise high injection shot pressure, use this type of methods comparison good.

         generate viscous 滞膨胀 mold, from injection machine lower separation understanding, use add hot methods make products soft rear lower. due to rigid property mold, from outer use sheet/plate strong/high 化夹紧.
