newmatt Posted March 18, 2015 Report Share Posted March 18, 2015 I was going to attempt to dry press some tiles using a mold and hydraulic press. It would make life much easier if I could dry and fire the tiles while still in their molds. Are there any common metals (steel, stainless, etc) that can withstand common kiln temps? Sorry for the newbie question. Thanks,Matt Link to comment Share on other sites More sharing options...
Benzine Posted March 18, 2015 Report Share Posted March 18, 2015 After some quick research, stainless steel doesn't melt until well above, what most kilns fire to. With that said, the intense heat will weaken, and probably distort the mold. Personally, I wouldn't do it. Link to comment Share on other sites More sharing options...
perkolator Posted March 18, 2015 Report Share Posted March 18, 2015 clay or refractory mold is the only material i can think of that would work for repeated use. Link to comment Share on other sites More sharing options...
Mark C. Posted March 18, 2015 Report Share Posted March 18, 2015 The short answer is no metal that can withstand common kiln temps. My common kiln temps are 2400 but even low fire will cause metal issues. Your mold can be made from ceramic materials and work just fine.

neilestrick Posted March 18, 2015 Report Share Posted March 18, 2015 Shrinkage could be an issue, as the mold will not shrink at the same rate as the clay unless it is made of the same clay. Thickness will also be an issue, since to withstand the pressure of dry pressing the mold would have to be very thick, and would probably not survive firing.

newmatt Posted March 18, 2015 Author Report Share Posted March 18, 2015 Thanks for all of the replies. A ceramic mold seems like a great solution from a temperature resistance standpoint. However, metail will be needed if dry-pressing for the pressures required. Will have to remove the metal filter after drying and before firing.

oldlady Posted March 19, 2015 Report Share Posted March 19, 2015 why do you want to do this? Link to comment Share on other sites More sharing options...
Marcia Selsor Posted March 19, 2015 Report Share Posted March 19, 2015 You could try a "ludo" recipe..plaster Nd silica for bronze casting But it would need to withstand the high pressure. And the temperature in the kiln. Marcia Link to comment Share on other sites More sharing options...
Tyler Miller Posted March 19, 2015 Report Share Posted March 19, 2015 I think your best bet would probably be to just invert the mould after pressing and slide the tiles into a setter. That's basically how it's done large scale. Even if you could find a mould suitable for your purposes, you'd be looking at a pretty high cost to productivity ratio. You'd need a mould for every tile and that's a HUGE number if you're using a bulk manufacturing method like dry pressing. Kiln shelves and tile setters are a lot cheaper than metal, far more durable too. Link to comment Share on other sites More sharing options...
