不 positive 确 操 as conditions, loss bad machine and injection molding parts mold generate very more molding disadvantages, lower provide solution methods 供参考. is decrease/reduce machine time, and can fast 找出操 as issues causes, as 人员应 has most good injection molding parts machine type conditions in “ injection molding parts molding conditions table/sheet ” upper, day rear solution issues 时参考之 use. injection molding parts processing 知, provide 附录资 material is full 精确, for material property and property --我 injection molding parts processing 并不承担任何 responsibility, use 人应自行决定资 material can use property. (1) formed product 不完整 fault/failure causes methods plastics temperature degree low improve/increase 熔胶筒 temperature degree pressure low improve/increase pressure amount increase more amount gate sleeve/set and 射嘴配 combined positive, plastics heavy new adjustment its combined front time short increase time speed degree slow add fast speed degree low pressure adjustment heavy new adjustment injection molding parts mold temperature degree low improve/increase injection molding parts mold temperature degree injection molding parts mold temperature degree heavy injection molding parts mold water tube/pipe injection molding parts mold gas defect 恰当位置 add degree gas 孔射嘴 temperature degree low improve/increase temperature degree 进胶不平均 heavy injection molding parts mold 溢口位置浇道 or 溢口太 small add large or plastics inner lubricant increase lubricant back pressure 不足稍 increase back pressure 胶圈, screw abrasion loss remove 检查修理射胶 amount more relatively large specifications injection molding parts machine products thin use nitrogen gas 射胶(2) products shrinkage fault/failure causes methods inner 进胶不足熔胶 amount add amount pressure low high pressure back pressure pressure high back pressure force time short long time speed degree slow fast speed 溢口不 balanced injection molding parts mold 溢口太 small or 位置射嘴孔太 fine, plastics in 浇道衬 sleeve/set inner solid, decrease low back pressure 效果. injection molding parts mold or more 换射嘴 material temperature high low material temperature mold temperature 不当整适当 temperature degree cooling time 不够延 cooling time pressure more 射胶终止应 in most front product or its and thick formed product design amount large more relatively fine injection molding parts machine 胶圈, screw abrasion loss remove gate small, plastics solid back pressure function add large gate dimensions (3) formed product mold sticking fault/failure causes methods filler saturated reduce pressure, time, speed degree and amount pressure high reduce pressure amount more decrease small amount time long decrease small 射胶间时 material temperature high reduce material temperature material make separation saturated more large small or injection molding parts mold temperature degree high or low adjustment mold temperature and versus for temperature degree inner has demolding 倒角修 injection molding parts mold remove injection molding parts mold surface light slip abrasion injection molding parts mold demolding formed true mold opening or ejection decrease slow, or injection molding parts mold add gas equipment injection molding parts cycle short add strong/high cooling demolding agent 不足略 is increase demolding agent use amount (4)浇道( water 口) mold sticking fault/failure causes methods pressure high reduce pressure plastics temperature degree high reduce plastics temperature degree large injection molding parts mold cooling 不够延 long cooling time or reduce cooling temperature degree demolding 角不够修改 injection molding parts mold increase degree 浇道衬 sleeve/set and 射嘴配 combined positive heavy new adjustment its combined inner surface light or has demolding 倒角检修 injection molding parts mold outer has loss bad injection molding parts mold 无浇道抓销 add 设抓销 filler saturated reduce amount, time and speed degree demolding agent 不足略 is increase demolding agent use amount (5)毛头, flash fault/failure causes methods plastics temperature degree high reduce plastics temperature degree, reduce injection molding parts mold temperature degree speed degree high reduce speed degree pressure high reduce pressure filler saturated reduce time, speed degree and agent amount clamping or combined defect injection molding parts mold pressure increase pressure or more pressure relatively large injection molding parts machine (6) mold opening or ejection formed product fault/failure causes methods filler saturated reduce pressure, time, speed degree and amount mold temperature low rise high mold temperature demolding 角不够检修 injection molding parts mold has demolding 倒角检修 injection molding parts mold formed product demolding can balanced 脱离检修 injection molding parts mold 顶针不够 or 位置不当检修 injection molding parts mold demolding local generate true phenomenon mold opening can ejection slow speed, add gas equipment demolding agent 不足略 is increase demolding agent use amount injection molding parts mold design defect, formed product inner has more force formed product design slip block as time or 位置不当检修 injection molding parts mold (7)结 combined fault/failure causes methods plastics melt improve/increase plastics temperature degree, improve/increase back pressure, add fast screw speed injection molding parts mold temperature degree low improve/increase injection molding parts mold temperature degree temperature degree low improve/increase temperature degree speed degree slow increase fast speed degree pressure low improve/increase pressure plastics or has its it material plastics demolding how much use 胶模油 or amount use and large or small adjustment injection molding parts mold 熔胶接 combined 方离浇道口太远 adjustment injection molding parts mold inner gas troubleshooting and increase gas or 检查原 has gas is 否堵塞熔胶 amount use relatively large injection molding parts machine more demolding agent use or decrease/reduce demolding agent
