Die-cast Zinc Vs Aluminium castings
Die-cast Zinc Vs Aluminium castings
(OP)
Can anyone advise me what problems I may encounter if I change from a zinc die-casting to an aluminium one. This is based on the existing casting tool being worn and I can introduce a big cost saving using aluminium.
I understand I may need to increase rib thickness in certain areas.
Any help would be appreicated.
Thanks,

Al alloys require thicker walls, larger draft, and higher tolerances; also, they will have reduced die life. All of this is essentially due to the higher melt temperature of the Al alloys.
With modern design and manufacturing, the actual differences won't be very much.
