Sintering Furnaces with Lifting Table LHT../17 LB Speed up to 1650 °C
High-quality heating elements made of molybdenum disilicide offer very good protection against chemical interaction between charge and heating elements.
Function and equipment
Due to their maximum temperature of 1650 °C and their large furnace chamber, the sintering furnaces of product line LHT ../17 LB Speed are perfectly suited for sintering translucent zirconia.
Equipped with special heating elements made of molybdenum disilicide, chemical interactions between the charge and the furnace components are almost avoided. The sintered material is placed in saggars made of technical ceramics. Up to two batch containers for max. 15 single crowns per level can be accommodated in the LHT 01/17 LB Speed. The LHT 02/17 LB Speed offers space for up to three saggars for max. 25 individual crowns per level and thus guarantees high productivity.
The sintering furnaces can also be operated with a drying function and a controlled cooling function due to their lift table.
For predrying, the furnace keeps a gap open while heating up to a defined temperature (e.g., 500 °C), ensuring safe removal of moisture from colored solutions. The controlled cooling
Key Facts
- Suitable for sintering zirconia from all leading manufacturers
- Ideal for high capacity utilization dental labs
- Maximum heating rate up to 1000 °C at 60 °C/min (LHT 01/17 LB Speed) or 20 °C/min (LHT 02/17 LB Speed)
- Fastest cooling time to 300 °C in 86 minutes (LHT 01/17 LB Speed) or 107 minutes (LHT 02/17 LB Speed)
- Sintering capacity of 30 to 75 single crowns/bridges and full arches
