Thread: Sand Casting. Who's done / doing it ?

I worked for ten years as senior technician at Masport Foundry. We did all types of cast iron. Grey, ductile, Ni hard, Hi chrome, semi, in green and hard sand. As you have worked out investment casting is the go for this type of work. The fine detail is not possible with green or hard sand.

In Auckland, Supreme Steel is a place worth talking to for this type of work. They do investment in steel and stainless. Sadly, not a lot of ferrous foundries left.
