injection molding parts viscous inner main/primary due to 模塑不善 ejection 不足, material 不足以 and positive mold design. if products viscous inner, injection molding process can can positive 常.

    （1） mold issues:

    if plastics viscous inner is due to material 不足造 formed, need using/adopting ejection machine 构;

    remove 倒切口（陷槽）;

    remove 凿纹, 刻痕以 and other 伤痕;

    improvement surface light slip property;

    light surface as direction and injection direction 一致;

    increase degree;

    increase has ejection 面积;

    ejection 位置;

    ejection machine 构 操 as;

    in deep 抽芯模塑 in, reinforcement true bad and gas pressure 抽芯;

    process in mold cavity is deformation, is deformation; mold opening 时, has 否偏移;

    decrease small gate dimensions;

    increase 设辅助 gate;

    heavy new gate 位置, （13）（14）（15）旨 in decrease/reduce mold cavity inner pressure;

    balanced more 模槽 充模 speed rate;

    anti injection 断流;

    if made parts design 不善, heavy new design;

    克服模子造 formed injection molding cycle 反常.

    （2） injection molding issues:

    ① increase demolding agent or improved demolding agent;

    ②调 positive material material to amount;

    ③ reduce injection pressure;

    ④ shrink short injection time;

    ⑤ decrease/reduce full pressure time;

    ⑥ reduce mold temperature;

    ⑦ increase injection cycle;

    ⑧克服 injection molding conditions formed injection molding cycle 反常.

    （3） material material issues:

    ①清 remove material material 污染;

    ② material material in add lubricant;

    ③ drying material material.

    （4） equipment issues:

    ①修缮 ejection machine 构;

    ② if ejection 行程不足, add long it;

    ③校 for sheet/plate is 否平行;

    ④克服 equipment formed injection molding cycle 反常.
