For the attached Aluminum casting file: Mesh=5mm Temp=765C Fill-time 14sec Material AL A356

1.When making the Mold 6-8 mm below top (as in reality), mesh fails.

2. When checking for Niyama (0.3) the all partis colored. Is it going to be bad part?

    Hi Uri,

     

    Can you please check the case definition. The riser cannot be outside the mold, how can you hold the melt ? It has to be either a sleeve or mold for the melt to hold

     

    Regards,

    1. When I make the Mold top height the same as the risers, (As in reality) the mesh fails.

    If I make the mold higher than the risers I miss the air cooling effect because of mold isolation.

    Please check and advise.

    2.  What about an answer regarding the Niyama problem?
