One thing with metal casting, metal shrinks a lot more than it cools than plastic does - if you want knobs and buttons the same size as the plastic ones you are going to need a mould that is a bit bigger than the originals. Are lots of other issues too. Will try and remember a bit more from my metallurgy lectures and give you some more tips later on ...
