Pressure drop exceeded maximum injection pressure limit (Low Confidence of Fill)

Indicates this area of the part is difficult to fill with plastic. The pressure drop at the selected point exceeds 100% of the maximum injection pressure.

What problems can high-pressure drop cause?

If the pressure drop is greater than the injection pressure, filling problems can occur. The part can short shot.

What to do next

When the pressure drop exceeds the maximum injection pressure set, some alternatives exist to improve the moldability of a part.

Increase the maximum injection pressure for this part

The pressure drop equals the set maximum injection pressure. To improve the confidence of this part filling, increase the injection pressure to compensate for the high-pressure drop through the cavity.

Alter part geometry

If the part consists of a complex and thin geometry, filling difficulties can require high injection pressure to complete the filling. If you cannot alter injection pressure, you can alter the part geometry.

Select a different material

Choose a material with a higher melt flow rate to require less injection pressure to fill the part.

Alter the polymer injection location

Move the polymer injection locations closer to the problem area, or add injection points to improve the likelihood of all sections of a part filling.
