　　3） screw bending. lower screw 检查, more screw.
　　4） screw has iron 屑. screw 检查, screw.
　　5） use separation table/sheet adjustment screw degree. 0.05mm left right is positive 常.
　　8, can 熔胶
　　处理 methods:
　　1）烧 bearings or 传动轴爆裂. separation screw again 熔胶并观察声音, more bearings.
　　2） screw has iron 屑. separation screw and material 筒, screw is has iron 屑, screw 清理.
　　3）熔胶阀堵塞. use 六角匙顶阀芯看 is 否移动, electrical magnetic 阀.
　　4）熔胶马达 loss bad. separation 开熔胶马达, 熔胶不转时, more or 修理熔胶马达.
　　5）烧 bad hot 圈. use use table/sheet is positive 常, more hot 圈.
　　6）插头松. 检查熔胶油 made is 否接触 defect, 接紧插头, 并检查 has 无24 electrical 源.
　　9, 熔胶时 back pressure can adjustment
　　处理 methods:
　　1） back pressure bad. lower material add large back pressure, screw is rear 退, back pressure 阀.
　　10, product has black spots
　　处理 methods:
　　1） screw has 积炭. 检查清洗 screw, material 筒.
　　2） material has and machine dry 净. upper material machine has 无灰尘, light material and 清理辅 machine.
　　3） separation 胶咀组 parts 腐蚀. separation 胶咀, more separation 胶咀组 parts.
　　4） method 兰, has 积炭. more 换.
　　5） Raw Materials 不洁. Raw Materials, more raw materials.
　　6） temperature degree high, back pressure large. 检查各段 temperature degree, drop temperature decrease back pressure.
　　11, screw mixed color defect
　　处理 methods:
　　1）材 material 间题. color powder quality, more material.
　　2） temperature degree low. 检查实际 temperature degree and material temperature degree, add high temperature degree.
　　3） back pressure low, back pressure, add large back pressure.
　　4）拌 material time short. add long material time or more formed mixing/compounding 头.
　　5）转 speed low. screw speed, improve/increase screw speed.
　　12, 无抽胶动 as.
　　处理 methods:
　　1） back pressure large. 检查手动熔胶时射咀喷胶 fast slow, reduce back pressure.
　　2）断线. 抽胶阀断线.
　　3） direction 阀阀芯不灵 active. use inner 六角扳手按阀芯检查 is 否自由 active 动, 清洗阀芯.
　　13, 熔胶时, 马达摆尾.
　　处理 methods:
　　1） bearings bad. 观察熔胶时 has 无异声, more bearings.
　　2）斜珠 bearings adjustment 不当. 观察传动轴 has 无摆动, heavy new adjustment 间隙.
　　3） screw deformation. separation screw 观察传动轴转动情况, more screw.
　　4）射台 rear sheet/plate copper sleeve/set abrasion loss 2 strip/profile deformation or solid filament 松. 观察二 sheet/plate copper sleeve/set is abrasion copper powder, more copper sleeve/set.
　　14, 射胶动 as 两次
　　1)射咀孔径太 small, 射胶时 retardant force large.
　　2）射咀发 hot bad, 检查发 hot or more 换.
　　3）检查 pressure amount has 无化.
　　15, screw causes
