injection molding machine 出现不射胶 and 射胶缓 slow, this for production is very 不利, to this issues, how solution? 星之瑞 according to front experience, summary injection molding machine 不射胶 and 射胶缓 slow causes and solutions, can large 家参考.
一, injection molding machine 不射胶 causes analysis:
1, injection molding machine electrical magnetic 阀 线圈烧 bad or 松脱
2, material electrical magnetic 阀阀芯, effect/influence electrical magnetic 阀 运转
3, pressure low, pressure low 不足以 achieve 射胶动 as
4, material temperature degree low, temperature degree low 不足以 achieve 射胶动 as
5, 射嘴堵塞
6, ring 破裂
7, active 塞密封圈 loss bad
injection molding machine 不射胶处理办 method:  
1, pressure table/sheet value; adjustment pressure
2, 检查止逆 ring; more 换止逆 ring     
3, 检查射嘴口; or nozzle
4, 检查线圈; or more 换线圈
5, electrical hot 圈: electrical hot is bad, meanwhile temperature degree is combined more electrical hot 圈, or heavy new material temperature degree 6, 检查阀芯; or more 换射胶 electrical magnetic 阀
7, 检查密封圈; more 换密封圈

二, speed degree slow
射胶 speed degree slow causes can can is:
1, speed 节流阀V13 adjustment positive 确.
2, injection shot electrical magnetic 阀阀心未 to 位, amount small, 导致射胶 speed degree slow.
3, injection shot pressure 不够. injection shot pressure for speed degree has effect/influence, therefore speed degree slow can can is pressure 不够.
4, active 塞油封 loss bad, internal generate inner 泄, can can formed pressure to need speed degree.
5, 射嘴堵塞 or for positive mold.
射胶 speed degree slow 处理办 method:
1, for amount adjustment, large amount.
2, for electrical magnetic 阀进行拆修.
3, large pressure （V5）.
4, 拆修射缸, more 换油封.
5, for injection molding machine 进行清理, positive.
