Re-melt zone, part insert result

The Re-melt zone, part insert result shows the location(s) where the insert may have melted when the part is injected.

This result is generated at the end of a Fill analysis using 3D analysis technology, where an insert is modeled.

Using this result

Re-melting occurs when the insert material temperature increases above its transition temperature because of heat transfer from the part. This result tells you where, on the boundary between the part and the insert, re-melting is likely to occur.

Re-melting of a thin skin increases structural strength between components. However, it is generally undesirable because it causes unpredictable changes to the properties of the insert, such as its exact shape or optical properties.

Things to look for

To prevent excessive re-melting, try one of these options:

• Decrease the injection temperature of the material.
• Change the insert or part material.
• Move the injection location to be further from the insert.

Note: Changes such as these can only be made using a licensed Autodesk Simulation Moldflow Adviser or Autodesk Simulation Moldflow Insight product.
