Gate Stringing/Drooling or High Gate Vestige

可能的原因建议的解决方案Possible CauseSuggested Remedies
浇口中有金属• 清除金属碎片并更换注嘴 （如果损 坏）。参见第 5.2.8 节。Metal in gate• Remove the metal chip and replace nozzle tip if damaged. Refer to Section 5.2.8.
阀针卡住• 更换阀针组件Seized valve stem• Replace the valve stem components
离浇口太近• 安装合适的注嘴。参见第 5.2.8.3 节。Too close to gate• Install the proper nozzle tip. Refer toSection 5.2.8.3.
离浇口太远Too far from gate
松动或脱落• 拆装注嘴。参见第 5.2.8 节。Loose or unscrewed• Remove and install the nozzle tip. Refer toSection 5.2.8.
接触浇口杯• 按照规格更换或重新加工浇口杯Touching gate detail• Replace or rework the gate detail to specifications
注嘴损坏• 更换注嘴。参见第 5.2.8 节。Damaged nozzle tip• Replace the nozzle tip. Refer toSection 5.2.8.
注嘴不正确• 安装合适的注嘴。参见第 5.2.8.3 节。Incorrect nozzle tip• Install the proper nozzle tip. Refer toSection 5.2.8.3.
注嘴隔热帽不正确• 更换注嘴隔热帽。参见第 5.2.14 节。Incorrect nozzle tip insulator• Replace the nozzle tip insulator. Refer toSection 5.2.14.
注嘴加热器不正确• 安装指定的注嘴加热器。参见 第 5.2.13 节。Incorrect nozzle tip heater• Install the specified nozzle heater. Refer toSection 5.2.13.
注嘴加热器接触板或模腔底• 重新定位加热器Nozzle heater touching plates or gate insert• Reposition the heater
减压不足• 增加机器减压行程Insufficient decompression• Increase the machine decompression stroke
冷却时间不足• 延长模具冷却时间Insufficient cooling time• Increase the mold cooling time
阀针式浇口气压• 提高气压Valve gate air pressure• Increase the air pressure
阀针式浇口定时• 改变空气阀顺序 / 定时Valve gate timing• Change the air valve sequence/timing
注射量过大• 减少注射量Excessive shot volume• Decrease the shot volume
保压时间过长• 缩短保压时间Excessive hold time• Decrease the hold time
浇口损坏• 按照规格更换或重新加工浇口杯Collapsed or damaged gate• Replace or rework the gate detail to specifications
阀活塞不工作• 清洁阀针衬套Valve piston not functioning• Clean the valve bushing
• 更换活塞密封圈。参见第 5.2.12 节。• Replace the piston  seal. Refer toSection 5.2.12.
• 检查活塞是否损坏• Check the piston for damage
• 检查气缸是否损坏• Check the cylinder for damage
• 检查阀针是否损坏• Check the valve stem for damage
浇道加热器与板接触• 重新定位浇道加热器Sprue heater touching plate• Reposition the sprue heater
热电偶失效• 按要求更换分流板、浇道或注嘴热电偶Defective thermocouple• Replace the manifold, sprue or nozzle thermocouple as required
加热器不工作• 检查并更换浇道、分流板或注嘴上所有 损坏的加热器Heaters not functioning• Check and replace all defective heaters on the sprue, manifold or nozzle
熔料温度过高• 降低熔料温度Melt temperature too high• Decrease the melt temperature
浇口冷却不足• 增加浇口处的模具冷却Gate not cooled enough• Increase the mold cooling at the gate
