12.5.2 Blisters or Bubbles

The finished product contains small gas or air filled pockets or cooling voids.

Probable Cause:

1. Molding Machine

• Low injection pressure

•

Back flow valve malfunctioning

• Suck-back cycle too long

• Rapid plasticizing

• Trapped air in feed

• Feed error

2. Mold

• Trapped or volatile gas

• Low mold temperature

• Poor thin / thick transition phase

• Inadequate venting

3. Material

• Overheating of resin

Solution (in sequence):

1.  Verify control and / or holding pressure
2.  Increase back pressure
3.  Increase mold temperature
4.

Inspect back flow valve

5.  Ensure proper venting
6.  Increase gate size
7.  Decrease vent land length
