<p>This invention concerns a mold and method for fabricating the mold. The mold in accordance with the invention is essentially comprised of sulfur, into which is mixed a filler material having a particle length of at least 1.5 times the particle thickness. The mold is fabricated by producing the sulfur and filler material into a gel-like molten mix, which is then formed into the desired shape, after which the form-shaped mold of the yet molten mold material is rapidly cooled by its surface in order to solidify the filler-containing sulfur mix. The molten mold material is advantageously produced by heating a mix comprised of sulfur and fine-milled iron slag or wollastonite, with a hydrocarbon fraction such as diesel oil added to it, to a temperature of approx. 115...160°C. The mold in accordance with the invention can be stripped by heating, allowing for the reuse of the mold material.</p> |
