Is this really a molding process? My instincts say no, but I don't have any references to back it up right now. Wizard191 (talk) 18:31, 14 August 2008 (UTC)Reply

Casting & moulding

edit

What's the difference? Is there a difference? My feeling is that casting takes place at atmospheric pressure, and involves liquids which flow easily, whereas moulding involves more viscous stuff that needs additional pressure beyond its own weight to move it. On that basis powder metallurgy is only moulding if coining and stamping are also moulding, as thepowder flows freely into the die and is only then subject to higher forces. Difficult, innit?

I suspect you are right, but having come from lost-wax casting, and seeing that there is only Mold (cooking implement) to cover all forms of mold/mould, I think this article (since it is so short) would be better renamed Mold (manufacturing) so that it can cover all types of process in a top-level way. Pottery made by pressing clay into a mould is certainly moulding not casting. Johnbod (talk) 03:48, 13 December 2013 (UTC)Reply
