HI everybody,
in reality before you can start with injection moulding the mould has to be heatet up to working temperaturen.
And then starts the injection molding process.
With bad cooling layout you already get here very different mold surface temperatures.
Today cool fem starts with constant temperature in the mold and it calculates with cooling of the melt even when you start it from 25°C.
And this is not real.
So it would be very good if there is a new analysis sequence in moldflow, perhaps called mold heating,
that calculates the temperature just in the mould prior starting a cool fem analysis from production start up and uses the temperature
distribution in the mold as starting boundary conditions for cool fem from production start up.
- more precise results for cool fem
- more precise warpage results
- getting real information how long it takes to get the mold to working temperature
- and how long it takes in njection molding to get a stable process
