        塑 parts 出现银纹

        因 plastics water 份, mixed 料不 uniform, injection molding gas, additives or demolding agent more.

        1 add strong/high back pressure;2 decrease slow injection molding speed 度;3 清理料筒;4 improve/increase mold temperature;5 改 gate 位置;6 expand large 流道 and gate;7 烤料;8 料斗 in 安装红 outer 线灯.

         plastics interface defect

        因 plastics temperature 度太 low, 不 can solvent or gas 体排泄不足导致兩股 above separation 流 mixed combined generate 发狀 fine or bubbles.

        1 improve/increase 料 temperature;2 improve/increase temperature;3 increase speed;4 接缝线处设冷料池;5 add gas 口;6 改变 gate or increase gate;7 不 need use demolding agent;8 转 use 易流动 low viscous 度 原料.

        塑 parts 出现空洞

        因 plastics in 熔料 solid 化期间 surface low temperature 模壁, shrinkage in thick 壁段而造 formed 空洞, or gas formed 空洞.

        1 improve/increase pressure and pressure 力;2 延 long injection time;3 降 low 料筒 solid temperature 度;4 削 decrease thick 度至6mm below/following, necessary 时设置 and other thick 肋线, and remove more thick;5 expand large gate;6 shrink short 流道;7 调匀 mold temperature;8 更改 gate 位置, troubleshooting gas.

        塑 parts 欠注

        因 machine injection molding and property can 不足, 料流 or 缺料不良, gate 截面太 fine, 模壁太 thin or gas 不良.

        1 increase 注料 speed 率, still 不足则需换更 large machine;2 装 anti 漏注阀式螺杆;3 improve/increase pressure;4 improve/increase 料筒, solid and mold temperature 度;5 检查 electrical hot fault/failure;6 查注嘴 is 否堵塞, increase ring speed 度;7 improve/increase mold gas can 力;8 add large gate 截面;9 increase product thick;10 add 设助线, renovation 料流;11 selection low viscous 度原料;12 add lubricating 滑 agent.

         clamping extrusion plastics

        因料 temperature or pressure high, or 锁模力不足, mold defect

        1 降 low pressure or 料筒 temperature 度;2 shrink short injection molding time;3 decrease/reduce 注料 speed 率;4 改 use high 锁模力 machine 械;5 renovation clamping surface combined and 清理 clamping surface;6 转 use low viscous 度原料.

        塑 parts surface 出现凹痕

        因塑 parts surface 误时冷却引致凹痕

        1 increase injection molding speed 率;2 improve/increase inner pressure;3 降 low 料筒 temperature 度;4 improve/increase injection molding 流量;5 increase speed;6 延 long 注时;7 make mold temperature 度 uniform;8 更改 gate 位置;9 expand large gate;10 shrink short mold 流道.

        塑 parts 呈扭曲 deformation

        因 injection molding 残余应力松弛, 导致塑 parts deformation 扭曲.

        1 降 low pressure;2 降 low 料筒 temperature 度;3 延 long 冷却 time;4 调匀塑 parts thick and demolding as;5 添设 demolding 锁;6 改变 gate 位置;7 调匀 mold temperature.

        塑 parts viscous mold cavity in

        因 mold 锥度度 fine, pressure high or type 不良.

        1 降 low pressure;2 降 low 料筒 temperature 度;3 increase mold 锥度;4 改良模 type and remove 凹槽;5 adjustment mold temperature;6 转 use demolding property 良 good material 料.

        塑 parts surface 出现纹 or color

         plastics hot separation understanding, 榄头圈 abrasion loss

        1 降 low 料筒 temperature 度;2 shrink short in as time;3 decrease low speed;4 mold increase gas speed 率;5 expand large gate;6更换 wear resistant and 榄头圈.

        塑 parts color 偏差

        因 temperature 度 color powder 原料 and machine 械清理导致 color 偏差.

        1 调 relatively temperature 度;2 清理 machine 械;3 原料 color 底偏差;4 mixed 料不 uniform;5 转换 machine 械;6 color powder 偏差;7 mold 不同;8 烘料.

        塑 parts color 起点

        因颜料 expand dispersion property can or as issues

        1 调校辘料 time;2 increase expand 油;3 increase expand dispersion agent or expand dispersion 油;4 will color powder 筛.

        塑 parts 出现黑纹

        因操 as, 清理 and ring issues 引致黑纹.

        1 machine 械清理, 射咀清理;2 decrease/reduce 残留料量;3 ring 境清理4 换 use wear resistant 榄头介指.

        塑 parts 起纹

        因颜料 expand dispersion, 啤塑程序引致出现黑纹.

        1 increase back pressure;2 decrease/reduce 残留料量;3 add long 储料;4 调校 temperature 度;5 color powder 转换;5 use expand dispersion agent.

        塑 parts black spots

        因污染引致 black spots

        1 清理 machine 械;2 清理 ring 境;3 更换原料;4 检查颜料 is 否污染.

        塑 parts 起白云白点

        因 temperature 度, mold, 原料, color powder expand dispersion property can and 辘料程序, 引致起白云白点.

        1 调校 temperature 度;2 改良 mold;3 转换 fast 流量原料;4 add expand dispersion agent or 油帮助;5 如 shallow color 查看辘料程序.
