Mold filling
¬ Options
¬ Avoiding gas traps
¬ Smooth, turbulence free filling pattern
¬ Avoiding cold shots
¬ Obstacles
¬ Not any gating position for filling is possible
to realize due to tooling restrictions.
¬ An optimal gating position for filling is not
necessarily optimal for feeding.
¬ Flow aids lead to heavy sections, and
therefore to shrinkage defects
The value of casting simulation increases
with an early integration in the design
process, because design modifications are
easy and allowed
¬ In die casting, a lot of series production
problems and additional costs can be
avoided by a sound design for castability
¬ Squeezen is effective, but leads to sensitive
production conditions and should be
avoided
