Mold thermal Expansion

HI everybody, 

 

I know what mold thermal expansion means. But how does this effekt excactly the simulation.

Does anybody knows more.

Hi,
I assume you mean the setting of:
Consider mold thermal expansion 
which is if you want Warp analysis to consider the effect of mold thermal expansion on the warpage and/or molded-in stress levels in the part.

During injection molding, the mold expands as the temperature increases, causing the cavity to become larger than its initial dimensions.
This cavity expansion helps to compensate for part shrinkage during cooling, resulting in actual shrinkage that is smaller than that predicted without accounting for thermal expansion of the mold.

Note: If you use this option, ensure that a suitable mold material has been selected.
This is where the key material property used by this option - the coefficient of thermal expansion of the mold - is defined.

Hope this clarifies.

Regards,
Berndt

Most of the materials used for injection molding will have less thermal expansion.

Like P20, H13 grades.
