If you can print the pattern and supply it to the foundry, the cost will be low. But you should talk to the foundry about how to make the pattern. Some patterns will warp as they cool. I think it has to do with the part's thickness, or rather if there are thick and thin parts in the same pattern. Also, some patterns will shrink as they cool, and you need to design the pattern differently from the final part. I know someone who wanted to make some lighter-than-normal cast iron cookware, and the foundry said the pattern was too thin in some places.
But as you made the pattern in CAD you can print it can give it to the foundry and they can tell you, then fixing it is very easy, not nearly as hard as making a new wood pattern. Unless you have a lot of experience with making cast iron parts, you want to use a LOCAL foundry where you can talk to the person there in person. Then he can tell you how to redesign the pattern if that is required. You need to follow their design rules On Mon, Apr 3, 2023 at 5:46 AM Todd Zuercher <to...@pgrahamdunn.com> wrote: > Google up some names and make some phone calls.
