可能的原因建议的解决方案Possible CauseSuggested Remedies
模具冷却不足• 检查冷却水流量MoldInsufficient cooling• Check the water flow
• 清洁冷却水通道• Clean the water channels
模具过热• 降低模具 （尤其是模芯侧）的冷却液 温度Mold too hot• Decrease the mold coolant temperatures, especially on the core side
成型表面模腔损坏• 对模腔进行修理并重新抛光Molding surfacesDamage to cavity• Repair and repolish the cavity
模芯下凹堵塞• 清洁下凹Undercuts in core are plugged• Clean the undercuts
拐角和凹槽口挂料• 清洁并抛光拐角和凹槽Hang-ups in corners and notches• Clean and polish the radius corners and notches
机器设定开模过快• 降低开模速度Machine setupMold opens too fast• Decrease the mold opening speed
调平并对准模具半模• 检查模具是否水平和对准。参见 第 5.3.2 节。Level and alignment of mold halves• Check the mold for proper level and alignment. Refer to Section 5.3.2.
顶针设置过早• 调整顶针设置以获得正确的定时Ejector setting too early• Adjust the ejector setting for correct timing
工艺设置不正确• 减少余料。ProcessingIncorrect settings• Decrease the feed cushion.
• 降低背压。• Decrease the back pressure.
• 调整螺杆转速。• Adjust the screw RPM.
• 降低注料速率。• Decrease the injection fill rate.
• 降低保压压力。• Decrease the hold pressure.
• 缩短保压时间。• Decrease the hold time.
开模之前产品未冷却• 延长冷却时间。Product not cooled before mold opening• Increase the cooling time.
温度过高• 降低熔料和热流道的温度。Temperatures too high• Decrease the melt and hot runner temperatures.
模芯空气顺序设定过早• 更改模芯空气定时。Core air sequenced too early• Change the core air timing.
原料熔料过热• 降低熔料和热流道的温度。ResinMelt too hot• Decrease the melt and hot runner temperatures.
原料污染• 清除料斗、干燥机等中的污染原料并对 注塑单元进行清料。请参见机器文档。Contaminated resin• Clean contaminated resin from the hopper, dryer, etc., and purge the injection unit. Refer to the machine documentation.
颗粒大小不均• 使用大小更均匀的颗粒混合物。Not-uniform particle size• Change the pellet mix to a more uniform size.
原料不正确• 更改原料类型。Incorrect resin• Change the resin type.
色母料浓度比不正确• 调整色母料浓度比。Incorrect color concentrate ratio• Adjust the color concentration ratio.
