Pressure drop exceeded maximum injection pressure limit

Indicates this area of the part can have poor quality. The pressure drop is too high at the point you selected, compared to the maximum injection pressure.

The pressure drop is the drop in pressure from the initial injection pressure to the pressure recorded at the moment the part was filled, for the entire model. The lower the pressure drop values recorded, the more likely the part fills completely.

If a part has a yellow or red Quality Prediction result, find out why. If it is due to high-pressure drop, make some of the changes recommended here.

If the part is mostly green with some small yellow areas, it can be acceptable. However, carefully examine the other result displays to see exactly how and where the results went wrong.

What problems can high-pressure drop cause?

If the pressure drop is greater than 80 percent of the injection pressure, there can be filling problems. In particular, the part can short shot.

What to do next

Some options are available to improve a bad pressure drop result:

Increase the maximum injection pressure

To improve the confidence of the part filling, increase the injection pressure.

Move the injection location closer to the problem area

This action can have an impact on other areas of the part.

Add additional injection locations

This action can cause the formation of weld lines in unacceptable locations.

Change part geometry

If the part consists of a complex and thin geometry, this condition can cause the short shot. You can thicken thin sections, or reduce the complexity of a flow path.

Select a different material

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