A Design Study in Rapid Prototyping for Castings                                        

Design Issues  -- Thin Wall Considerations

  • The casting design engineer has to ensure that the molten metal will flow smoothly and rapidly into all sections of the die to produce a flaw free component.
    -- Molten magnesium cools quickly and can solidify prematurely in thin, very narrow side wall sections, blocking metal flow into the mold.

  • For thin wall castings,   it is important to decide what features (cut-outs, holes, slots) would severely restrict fluid flow in the mold.

  • Those features should be machined, rather than formed by cores in the mold.
