Sintering Furnaces 

---

All the furnaces of our new series are real space savers and build in a very compact way. Thanks to the very high temperatures – up to 1800 °C – these furnaces are ideal for the material technologies of the future.

Some models allow firing without oxygen under vacuum, thus making Prettau^® Zirconia even more translucent and they can also be used for sintering sinter metal. All furnace parts are easily replaceable without the need for special technical assistance.

Sinterofen 300S – Sintering furnace for the sintering of Zirkonzahn’s sinter metal  

---

		SiC heating elements
		High performance vacuum pump for oxygen-free sintering
		Sintering without shielding gas
		Sintering approx. 50 Sintermetall elements, 2 full arch bridges or 6 bars in one cycle
		Modern high quality design (with Sicurit glass panels)
		4,3” color touchscreen control panel which displays the sintering process and remaining time
		Updatable via USB port
	The compact Sinterofen 300S sintering furnace is in the typical Zirkonzahn design fully glazed and has been developed especially for the sintering of our Sintermetall. The high performance vacuum pump enables oxygen-free sintering without the use of shielding gas. Thanks to the very long-lasting SiC heating elements, the furnace requires low maintenance and is very robust. The optimal temperature distribution in the sintering furnace, the shrinkage factor of our Sintermetall of just 7% as well as its torsional stability allow the sintering of all milled dental restorations from single crowns, metal structures, telescopes, bars and attachments up to full arch bridges with a total lack of stresses in the metal. Using the Sintering Tray Sintermetall XL 300S (for small structures of up to 5 elements) up to 50 Sintermetall elements can be sintered within the large sintering tube of the furnace. With the specially developed Sintering Holder XL 300S (patent pending), it is possible to sinter two full arch bridges or up to six bars in one sintering cycle. After the eight-hour sintering cycle, the oven cools down automatically and controlled. The sintering process as well as the remaining sintering time can be checked at any time on the easy-to-use 4,3 ” colour touchscreen control panel. The Sinterofen 300S is quickly and easily updateable via USB port.
