|
產生現象原因： |
|
|
|
當水分、空氣未除盡時，即會產生此狀況；或模內有空氣或塑料局部產生過熱，亦會造成水痕；另外，水痕可能來自於其他因素，需詳加觀察，以判定結果。 |
|
|
|
Reason: |
|
|
|
Water & Air not complete remove and cause the problem. It might be also case by the other reason so need to inspection in process. |

|
|
產生水痕對策： |
|
|
|
1. 塑膠料需預先乾燥，較不會產生此現象。 2. 背壓、螺桿轉速適當調整，成品較優質。 3. 螺桿鬆退距離不宜太長，完善成品。 |
|
|
|
Countermeasure: |
|
|
|
1. The material dry in advance. 2. Adjust the Back pressure & speed of screw rotation. 3. The distance of screw suck back to long. |
