塑膠（jiāo）產品生產時都會遇到產品注塑出來缺膠以及開（kāi）裂的問題，今天
山東模具製造廠家就為大家分析（xī）一下相關（guān）的應對方法，供大家（jiā）參考使用。
During the production of plastic products, we will encounter the problems of lack of glue and cracking after injection molding. Today, Shandong mold manufacturers will analyze the relevant countermeasures for your reference.
模具注塑過程中產品缺膠（jiāo）
The product is short of glue during mold injection
原因一：料溫，模溫（wēn）太低（dī）
Reason 1: the material temperature and mold temperature are too low
改善對策：是提高，料管溫度和模具溫度。
Improvement measures: increase the temperature of the material pipe and the mold.
原因二：噴嘴，進膠點尺（chǐ）寸太小。
Reason 2: the size of nozzle and glue inlet point is too small.
改善對策：適當加大噴嘴及進膠點。
Improvement measures: appropriately increase the nozzle and glue inlet point.
原因（yīn）三（sān）：模具排氣不良。
Reason 3: poor mold exhaust.
改善對（duì）策：可增開排氣孔。
Improvement measures: open more exhaust holes.
原因四（sì）：噴嘴冷頭或者堵塞
Reason 4: nozzle cold head or blockage
改善對策：可通過（guò）清除射嘴雜物，提高射嘴溫度來解決
Improvement countermeasures: it can be solved by removing sundries from the nozzle and increasing the temperature of the nozzle
原因五：射出速度和壓力不夠
Reason 5: insufficient injection speed and pressure
改善對策：解決方法就是提高射速，射壓。
Improvement countermeasures: the solution is to increase the shooting speed and pressure.
模具注塑過程中產品（pǐn）開裂（liè）
Product cracking during mold injection
（1）加工壓力過（guò）大、速度過快、充料愈多、注射、保壓時間（jiān）過長（zhǎng），都會造成內應力過大而（ér）開裂。
(1) Too much processing pressure, too fast speed, more filling, and too long injection and pressure holding time will cause excessive internal stress and cracking.
（2）調節開模速度與壓力防止快速強（qiáng）拉製件造成脫（tuō）模開裂。
(2) Adjust the mold opening speed and pressure to prevent demoulding cracking caused by rapid strong drawing.
（3）適當調高模具溫度，使製件易於脫模，適當調低料溫防止分解。
(3) Appropriately increase the mold temperature to make the parts easy to demould, and appropriately reduce the material temperature to prevent decomposition.
（4）預防由於（yú）熔接痕，塑料降解造成機械（xiè）強度變低而出現開裂。
(4) Prevent cracking due to low mechanical strength caused by fusion marks and plastic degradation.
（5）適當使用（yòng）脫模劑，注（zhù）意經常（cháng）消除模麵附著的氣霧等物（wù）質。
(5) Use release agent properly, and pay attention to often eliminate the aerosol and other substances attached to the mold surface.
（6）製件殘餘應力，可（kě）通過在成型後立即（jí）進（jìn）行退火熱處理來消除（chú）內應力而減（jiǎn）少（shǎo）裂紋（wén）的生成。
(6) The residual stress of parts can be eliminated by annealing heat treatment immediately after forming to reduce the generation of cracks.
以上總結是比較（jiào）有代表性的方麵，實（shí）際操作當中，可能還（hái）會有其（qí）它情況導（dǎo）致的注塑成型問（wèn）題，具體（tǐ）根據實（shí）際情況解決（jué）。更多相關內容就來我們網（wǎng）站
