12.5.18 Stringing

The finished product has thin plastic strings attached to the sprue.

Probable Cause:

1. Molding Machine

• High back pressure

• High nozzle temperature

2. Mold

• Incorrect sprue

3. Material

• Melt strength inadequate

Solution (in sequence):

1. Reduce back pressure
2. Modify nozzle temperature
3.

Modify temperature profile

4.  Eliminate sprue breaks
5.  Increase cooling time
6.  Decrease mold temperature at the gate
