Investment casting of Al 356
Investment casting of Al 356
(OP)
Hi,
I am contemplating casting a product in Al 356. If I make a mold to make wax patterns, does anybody know the allowance I need to apply to apply to the cavity to account for the wax shrinkage, and the Al shrinkage.
Regards Dave

RE: Investment casting of Al 356
approximate shrinkage allowance for wax 0.4%
approximate shrinkage allowance for Al alloys 1.1 - 1.3 %
approx. total allowance 1.5 - 1.7 %
Hoping this helps, with regards,
