注塑件缺陷的特征注塑過(guò)程不完全
Defect characteristics of injection molded parts the injection molding process is incomplete
可能出現(xiàn)問(wèn)題的原因：
Possible causes of problems:
(1)注塑速度不足。(2)塑料缺料(3)螺桿在行程結(jié)束處沒(méi)留下螺桿墊料。(4)運(yùn)行時(shí)間變化。(5)射料缸溫度太低。(6)注塑壓力不足。(7)射嘴部分被封。(8)射嘴或射料缸外的加熱器不能運(yùn)作。
(1) Insufficient injection speed. (2) Plastic material shortage (3) the screw did not leave screw padding at the end of the stroke. (4) Running time changes. (5) The temperature of the injection cylinder is too low. (6) Insufficient injection pressure. (7) The nozzle is partially sealed. (8) The heater outside the nozzle or injection cylinder cannot operate.
(9)注塑時(shí)間太短。(10)塑料貼在料斗后壁上。(11)注塑機(jī)容量太?。醋⑸渲亓炕蛩芑芰Γ?。(12)模溫太低。(13)沒(méi)有清理干凈模具的防銹油。(14)止退環(huán)損壞，熔料有倒流現(xiàn)象。
(9) Injection molding time is too short. (10) Plastic is pasted on the back wall of the hopper. (11) The capacity of the injection molding machine is too small (i.e. injection weight or plasticizing capacity). (12) Mold temperature is too low. (13) The antirust oil of the mold was not cleaned. (14) The retaining ring is damaged and the molten material has backflow.
方法：
resolvent:
(1)增加注塑速度。(2)檢查料斗內(nèi)的塑料量。(3)檢查是否正確設(shè)定了注射行程，需要的話(huà)進(jìn)行更改。(4)檢查止逆閥是否磨損或出現(xiàn)裂縫。(5)檢查運(yùn)作是否穩(wěn)定。(6)增加熔膠溫度。(7)增加背壓。(8)增加注塑速度。
(1) Increase injection speed. (2) Check the amount of plastic in the hopper. (3) Check whether the injection stroke is set correctly, and change it if necessary. (4) Check the check valve for wear or cracks. (5) Check whether the operation is stable. (6) Increase the melt temperature. (7) Increase back pressure. (8) Increase injection speed.
(9)檢查射嘴孔有沒(méi)有異物或未塑化塑料。(10)檢查所有的加熱器外層用安培表檢驗(yàn)?zāi)芰枯敵鍪欠裾_。(11)增加螺桿向前時(shí)間。(12)增料斗喉區(qū)的冷卻量，或降低射料缸后區(qū)溫度。
(9) Check whether there is foreign matter or unplasticized plastic in the nozzle hole. (10) Check all the outer layers of the heater and check whether the energy output is correct with an ammeter. (11) Increase the screw forward time. (12) Increase the cooling capacity in the throat area of the hopper, or reduce the temperature in the rear area of the injection cylinder.
(13)用較大的注塑機(jī)。(14)適當(dāng)升高模溫。(15)清理干凈模具內(nèi)的防銹劑。(16)檢查或更換止退環(huán)。
(13) Use a larger injection molding machine. (14) Properly raise the mold temperature. (15) Clean the rust inhibitor in the mold. (16) Check or replace the retaining ring.
注塑件尺寸差異
Dimensional difference of injection molded parts
注塑件缺陷的特征：
Characteristics of defects of injection molded parts:
注塑過(guò)程中重量尺寸的變化超過(guò)了模具、注塑機(jī)、塑料組合的生產(chǎn)能力。
The change of weight and size in the injection molding process exceeds the production capacity of the mold, injection molding machine and plastic combination.
Jinan injection molding manufacturer explained the causes of possible problems:
(1)輸入射料缸內(nèi)的塑料不均。(2)射料缸溫度或波動(dòng)的范圍太大。(3)注塑機(jī)容量太小。(4)注塑壓力不穩(wěn)定。(5)螺桿復(fù)位不穩(wěn)定。(6)運(yùn)作時(shí)間的變化、溶液粘度不一致。(7)注射速度（流量控制）不穩(wěn)定。(8)使用了不適合模具的塑料品種。(9)考慮模溫、注射壓力、速度、時(shí)間和保壓等對(duì)產(chǎn)品的影響。
(1) The plastic in the input injection cylinder is uneven. (2) The temperature or fluctuation range of the injection cylinder is too large. (3) The capacity of the injection molding machine is too small. (4) The injection pressure is unstable. (5) Screw resetting is unstable. (6) The change of operation time and solution viscosity are inconsistent. (7) The injection speed (flow control) is unstable. (8) Plastic varieties that are not suitable for molds are used. (9) Consider the influence of mold temperature, injection pressure, speed, time and pressure holding on the product.
