Metal Casting Methods

There are tell tale signs to everything made by one method or another. Why do you ask? Yes eject pins are used in sand castings at times.

I've just been introduced to the world of metal castings at my new job and wanted to learn as much as possible. If you could explain these tell tail signs of each casting method that would be great. As i stated in my original question I would like to be able to distinguish the different types of casting by sight. Any Information would be helpful.

Thanks

You don't say where your from, but the American Foundry-Mens Society has a vast amount of information available. They are located out of the Chicago IL area. Do a internet search and you will locate them. You say you have been introduced to the metal casting world at your new place of employment. You might see if they are a member of the Society as this allows better access to their materials.

Let us know what type of castings your company does. It would help to point you in the right direction.

All types of casting from centrifugal, lost foam, sand, to gravity fed and high pressure die casting. Basicly what im looing for is a reference that will give me a detailed discription of each casiting methods end product as far as surface finish, texture, look and any signs of identifying one method from the other by sight and feel of the end product. Any material containing this information would be very helpful. I have done alot of reading on the processes of each casting method but want to find a guide to distinguishing them without the knowledge of the alloy and the mechanical properties needed for the end parts application. To tell the method by sight and feel alone. Thank you for any information provided.
