12.5.12 Parts Sticking to Cavity

The finished product does not properly release from the mold (female side).

Probable Cause:

1.  Molding Machine

•  High injection pressure

•  High injection speed

•  Long holding time

•  High material feed

2.  Mold

•  Hot cavity

•  Cold mold

•  Defective mold surface

3.  Material

•  Melt too hot

Solution (in sequence):

1. 

Confirm cycle time for cooling

2.  Reduce injection pressure
3.  Reduce injection hold time
4.  Reduce injection speed
5.  Reduce injection time
6.  Adjust feed
7. 

Inspect mold finish

8.  Increase mold opening cycle
9.  Lower mold temperature
10. 

Adjust differential temperatures

11. Inspect for appropriate mold release
