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.
If the pressure drop is greater than the injection pressure, filling problems can occur. The part can short shot.
When the pressure drop exceeds the maximum injection pressure set, some alternatives exist to improve the moldability of a 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.
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.
Choose a material with a higher melt flow rate to require less injection pressure to fill the part.
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.
