I need to make a 2 part mould in which to pour molten wax into for casting.
I need blocks of plastic around 150mm x 200mm x 60mm, does anyone know of a UK supplier? or even the name of a product?
The plastic I need to use just needs to be able to be cut cleanly in my cnc machine with a ball nose cutter and be suitable for holding molten wax.
So far I have made test moulds using wood (oak) but I need something that will release the solidified wax more cleanly.
