模具注塑（sù）成型過程中（zhōng）可能會遇到這樣和那樣的問題，有可能遇到的缺陷會（huì）是（shì）什麽呢？筆（bǐ）者告訴你，模具（jù）注塑成型（xíng）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? The author tells you that the following defects may be encountered in the process of mold injection molding:

注塑件缺陷的（de）特征注塑過程不完全，因為模腔沒有填滿塑料或注塑過程缺少某些細節。

The injection molding process is incomplete because the mold cavity is not filled with plastic or the injection molding process lacks some details.

可（kě）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)螺杆在行程結束（shù）處沒留下螺杆墊料。(4)運行時（shí）間變化。(5)射料（liào）缸溫度太低（dī）。(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。(9)注塑時間太短。(10)塑料貼在料鬥後壁上。(11)注（zhù）塑機容量太（tài）小（即注射重量或塑化能力）。(12)模溫太低。 (13)沒有（yǒu）清理幹淨模具的防鏽油。(14)止退環損壞，熔（róng）料有倒流現象。

(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) 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.

山東（dōng）模具製造（zào）廠（chǎng）家提供的（de）方法：

Solutions provided by Shandong mold manufacturer:

(1)增加注塑速度。(2)檢查料鬥內（nèi）的（de）塑料量。(3)檢（jiǎn）查是否正確設定了注射（shè）行程，需要的話進行（háng）更改。(4)檢查止逆閥是否磨（mó）損或出現裂縫。(5)檢查運作（zuò）是否穩定（dìng）。(6)增加熔膠溫度。(7)增加（jiā）背壓。(8)增加注塑速度。(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（biǎo）檢（jiǎn）驗能（néng）量輸出是否正確。(11)增加螺杆向前時間。(12)增料鬥喉區（qū）的冷卻量，或降低射料缸後區溫度。(13)用較大的注塑機。(14)適當升（shēng）高模溫。(15)清理幹淨模（mó）具內的防鏽劑。(16)檢查或更換止退環。

(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) 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) 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.
