Cooling mold temperature prevision

Anonymous — Fri, 27 Mar 2015 10:45:05 GMT

Hi everyone,

i have some hot spots on the mold ("temperature, mold" result) in a cooling analysis (BEM).

As starting data i set the coolant inlet 10° lower the mold temperature target (15° lower in the inlet connected to the circuit around the nozzles). The mold temperature target is 60°.

If i'm not wrong there isn't any other way to control the mold temperature.

We tried to improve the cooling circuit adding baffles. Now we still have these hot spots and the average mold temperature is high.

We are trying now to reduce again the inlet temperature to reduce the overall temperature.

The question is:

do you know which is the gap between the Moldflow results and the real temperatures? I mean if Moldflow can be wrong for 3-4 degrees or 0.1-0.2 degrees.

Is there any reference in the guide (or from the Autodesk team) ?

Thanks
