Shanghai Daoqin Plastics Co., Ltd.

  processing nylon material (pure nylon material and add nylon material), for/regarding use 普通开式射嘴 most Common issues is 射嘴漏 material or cold material 射不动胶. 射嘴漏 material or mold or in upper. mold effect/influence lower molding. in outer 浪费胶 material. production Common is: has can 射胶, has 时射不动胶. is can positive production, has using/adopting rear anti material mold, this a large amount of material 就漏掉.

      nylon and other low viscosity material, for requirements is: temperature degree need 足够, also can material. PA PET PPS and other low viscosity material temperature degree 足够时 very easy 发生漏 material, 由此便 has elastic 簧射嘴 or pressure 开关射嘴 application.

      elastic 簧射嘴 principle is use elastic force achieve 阀芯 开启 and 关闭. 当射胶时, elastic pressure shrink, 阀芯打开, 进行射胶. 不射胶时, elastic force 推动阀芯关闭射嘴, achieve high temperature 而不漏 material 目.

      elastic 簧射嘴现市面 upper has types basic structure: outer elastic 簧射嘴 and inner elastic 簧射嘴. outer elastic 簧射嘴 structure 直观, use Common issues is: temperature degree 不稳, has can 射胶, has can 射胶, elastic easy loss bad, also easy 出现阀芯漏胶. its causes is: elastic 簧位处不 can 安装发 hot temperature degree 不稳. inner elastic 簧射嘴因 can has 效 安装发 hot temperature degree stability. inner elastic 簧射嘴 is currently processing low viscosity material anti anti can 靠射嘴.

      is 此我司 design manufacturing types inner elastic 簧射嘴(already patent): can has anti anti 堵, elastic can resistant 450 degree temperature degree. already long time use 检验. suitable for machine and machine.

      for/regarding large type injection molding machine, due to structure causes, material inner material pressure large, add 抽胶也会出现漏 material, is 此我们 provide types pressure 开关射嘴, this type of 射嘴承受 ratio elastic 簧射嘴 more back pressure 而不漏 material. due to 射嘴 开启关闭时由 outer force formed, has structure causes formed pressure loss 失.

      using/adopting inner elastic 簧射嘴 can has anti 止漏胶堵胶. for/regarding ABS and other cold material formed water 花(or material 花), 安装油 pressure 开关射嘴 has very good improvement 效果.
