可能的原因建议的解决方案Possible CauseSuggested Remedies
模具排气孔堵塞• 清洁排气孔MoldVents blocked• Clean the vents
排气孔损坏• 按规格重新加工排气孔Vents crushed• Rework the vents to specification
浇口杯损坏• 按照规格更换或重新加工浇口杯Gate detail damaged• Replace or rework the gate detail to specification
机器注嘴半径和小孔与模 具不匹配• 更换适用的机器注嘴Machine nozzle radius and orifice not matched to mold• Replace the machine nozzle to suit application
热流道阀针式浇口阀针不能完全 打开或关闭• 检查空气管道是否接反Hot RunnerValve gate stem does not open or close fully• Check for reversed air lines
• 增加到阀针式浇口的空气压力• Increase the air pressure to the valve gate
• 改变空气阀顺序 / 定时• Change the air valve sequence/timing
• 清洁阀针和阀针衬套• Clean the valve stem and valve bushing
• 更换磨损或损坏的阀针式浇口部件• Replace worn or damaged valve gate components
浇道衬套加热器故障• 检查加热器并在需要时更换Faulty sprue bushing heater• Check the heater and replace if necessary
分流板加热器故障Faulty manifold heater
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 heater• Install the specified nozzle heater. Refer toSection 5.2.13.
热电偶故障 （浇道衬套、分流板或注嘴）• 检查热电偶并在需要时更换Thermocouple fault (sprue bushing, manifold or nozzle)• Check the thermocouple and replace if necessary
注嘴加热器松动• 紧固调整螺钉Nozzle heater loose• Tighten the set screw
注嘴加热器与板接触• 重新定位注嘴加热器Nozzle heater touching plates• Reposition the nozzle heater
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
注嘴松脱• 紧固注嘴Nozzle tip unscrewed• Tighten the nozzle tip
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.
工艺熔料温度太低• 提高挤出机温度ProcessingMelt temperature too low• Increase the extruder temperature.
• 提高分流板温度• Increase the manifold temperature.
• 提高注嘴温度• Increase the nozzle temperature.
• 提高浇道衬套温度• Increase the sprue bushing temperature.
• 提高模具冷却液温度• Increase the mold coolant temperature.
注料速率过低• 提高注料速率Injection fill rate too slow• Increase the injection fill rate
注塑压力过低• 提高注塑压力Injection pressure too low• Increase the injection pressure
螺杆 RPM/ 扭矩不正确• 调整螺杆 RPM/ 扭距Incorrect screw RPM/torque• Adjust the screw RPM/torque
保压时间过短• 延长保压时间Hold time too short• Increase the hold time
