Sharp
edges and corners on a die casting can directly affect
die life and tooling costs. |
The
features of the casting are replicated in the cavity of the casting
tool. If the component has sharp corners and sharp edges,
those features will be duplicated in the tool. But sharp
corners and edges in the tool act as stress concentrations and local zones of high
heat build-up. Both conditions can cause premature surface and corner cracking in the
tool and shorten tool
life.

Sharp
features in the component should be reduced with fillets and
radii whenever possible. |
