        模具注塑成型過程中有可能存在的缺陷

        來源:http://www.lasagnafarm.com/ 日期:2022-07-09

        模具注塑成型過程中可能會遇到這樣和那樣的問題,有可能遇到的缺陷會是什么呢?小編整理好了來告訴你,模具注塑成型過程中有可能遇到缺陷如下:
        Mold injection molding process may encounter this and that problem, what are the possible defects? Xiaobian has sorted it out to tell you that defects may be encountered in the process of mold injection molding, as follows:
        注塑件缺陷的特征注塑過程不完全
        Defect characteristics of injection molded parts the injection molding process is incomplete
        可能出現問題的原因:
        Possible causes of problems:
        (1)注塑速度不足。(2)塑料缺料(3)螺桿在行程結束處沒留下螺桿墊料。(4)運行時間變化。(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)注塑時間太短。(10)塑料貼在料斗后壁上。(11)注塑機容量太?。醋⑸渲亓炕蛩芑芰Γ?。(12)模溫太低。(13)沒有清理干凈模具的防銹油。(14)止退環損壞,熔料有倒流現象。
        (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.
        解決方法:
        resolvent:
        (1)增加注塑速度。(2)檢查料斗內的塑料量。(3)檢查是否正確設定了注射行程,需要的話進行更改。(4)檢查止逆閥是否磨損或出現裂縫。(5)檢查運作是否穩定。(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能量輸出是否正確。(11)增加螺桿向前時間。(12)增料斗喉區的冷卻量,或降低射料缸后區溫度。
        (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。(14)適當升高模溫。(15)清理干凈模具內的防銹劑。(16)檢查或更換止退環。
        (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:
        注塑過程中重量尺寸的變化超過了模具、注塑機、塑料組合的生產能力。
        The change of weight and size in the injection molding process exceeds the production capacity of the mold, injection molding machine and plastic combination.
        濟南注塑加工廠家講解可能出現問題的原因:
        Jinan injection molding manufacturer explained the causes of possible problems:
        (1)輸入射料缸內的塑料不均。(2)射料缸溫度或波動的范圍太大。(3)注塑機容量太小。(4)注塑壓力不穩定。(5)螺桿復位不穩定。(6)運作時間的變化、溶液粘度不一致。(7)注射速度(流量控制)不穩定。(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、時間和保壓等對產品的影響。
        (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.
