thickness die casting vs melting

[vale61]

Good morning,
Every now and then I get resentful.
I should design an equipment where to insert a particular aluminum box.
The material would be a 46100 between the possibilities I'm evaluating the meltdown.
having had to deal only with the prefusion I would like to understand gross (just to give an order of magnitude achi will fea) of how much I should increase the minimum thicknesses to obtain the same structural resistance.
I know that the question is a bit generic, but for the moment it would be enough for me to have an idea of maximum or to know that it is not possible to make a direct comparison between the two processes (I see that I do not know the different problems that could be in the merge on earth with die casting).
the box would have external size of about 300x300x100 (die casting thickness 3 mm)
Thank you 1000.
Bye-bye.

Well, the die casting is able to be precise, homogeneous and do not even need large overheads and scampanations for extraction. for melting on the ground, as for cast iron, it is all a little more coarse unless you make the soul of polystyrene resin and then put into the mold of earth. the allumino would take the polystyrene leaving you a very beautiful jet (technical for endothermic engines).
