Shanghai Daoqin Plastics Co., Ltd.

        描述: injection molding process in weight and dimensions ultra- mold / injection molding machine / plastics combined production can force.

         can can 起因以 and use remedy methods :

        1. injection molding machine

        A, 输入射 material inner plastics 不均.

        检查 has 无充足 cooling water material 斗喉以 maintain positive temperature degree.

        B, material temperature degree or scope/range large.

        检查 has poor or hot electrical 偶.

        检查 and temperature degree control device use hot electrical hot is belongs to positive type type.

        C, injection molding machine amount small.

        检查 injection molding machine injection molding amount and can force, rear and injection molding amount and small plastics use amount comparison.

        D, unstable injection molding pressure.

        检查 is 否每次运 as has stability melt material.

        检查回流 anti has 否漏, has need 就进行 more 换.

        检查 is 否错误 进 material setting.

        E, screw unstable.

         ensure screw in 每次运 as 时复回位置都 is stability, more 于0.4mm(0.16in) 变化.

        F, as time 变化, liquid viscosity 不一致.

        检查运 as time 不一致 property.

         use back pressure.

        2. mold

        A, gate separation by 堵塞.

        检查 is 否任何迹象显示 gate material in gate inner, especially is water gate.

        B, 不一致 mold temperature degree control.

        检查 used for mold cooling cooling is has temperature degree 变化.

        检查 mold cooling pipeline has 无堵塞.

        检查 cooling pipeline is positive versus 连.

        3. plastics

        A, plastics 变化.

        检查进 material amount large small 变化. ensure fine from use material in 筛掉.

        检查 is will plastics mixed combined in 一起.
