Warpage tolerance result

The Warpage tolerance result highlights those areas of the part where out-of-plane deflections exceed the specified warpage tolerance.

Warpage

The total warpage of the part is caused be several factors including differential shrinkage, caused by variation in shrinkage from region to region, and orientation effects, caused by variations in the magnitude of shrinkage parallel and perpendicular to the material orientation direction.

Things to look for

When viewing the Warpage tolerance result, watch for the following:

• The default tolerance matches your design tolerance.
• The location of the deflection. Warpage in some areas may be of less concern than in others.

Using this result

The Warpage tolerance result highlights those areas of the part where out-of-plane deflections exceed the specified warpage tolerance. If the warpage values are small, magnify the display using the Magnification tool in the Result Settings next to the legend.

The default tolerance is set at 86% of the maximum warpage. Use the legend slider to change the warpage tolerance to match your design requirements.

Next steps

The following options can be used to reduce warpage:

• Change the melt temperature
• Change the mold temperature
• Change the injection time
• Select a material from the database with a lower average nominal shrinkage. Materials that are gold rated for warpage have more complete material properties data.
• Move injection locations to create a balanced fill pattern
• Edit the simulation model to make wall thicknesses more uniform
• Edit the simulation model to increase the wall thickness.
