    Translucent Zirconia
    CoCr Alloys
    CAD/CAM Systems
  • Burnout Furnaces
  • Laser sintering
  • Model Casting

Recommended types

Designed as a table-top model with SiC heating rods, this comparably inexpensive high-temperature furnace offers numerous advantages when sintering non-translucent zirconia with an operating temperature of up to 1500 °C. Compared to other models, however, the costs for changing the heating elements are higher.The large heating chamber and fast heat-up times make this model a good choice for CAD/CAM machining of zirconia. The controller of the furnace is freely programmable for the individual sintering of the zirconia material. The high-temperature furnace is also designed for connection to the single-phase power grid.

Standard equipment

  • Tmax 1550  °C
  • Working temperature 1500  °C, increased wear and tear must be expected in case of working at higher temperatures
  • Single-phase connection (LHTCT 01/16)
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • Scope of delivery includes a starter set for charging on one level, additional levels as additional equipment
  • Adjustable air inlet
  • Type S thermocouple
  • Easy replacement of heating rods

Additional equipment

  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
  • Square saggar for charging of up to two layers (15 single crowns)
  • Lid for top saggar

Translucent Zirconia Sintering Furnace LHT …/17 LB Speed series

Due to their maximum temperature of 1650 °C and their large furnace chamber, the high-temperature bottom loading furnaces are perfectly suited for sintering translucent zirconia. The motor-driven lifting table significantly simplifies the charging of the high-temperature furnace. The all-around heating of the cylindrical furnace chamber ensures a very even temperature uniformity.

The high-temperature bottom loading furnaces are additionally equipped with a drying as well as a forced cooling function. For residual drying, the oven remains open gapwise during heating up to a defined temperature and thus ensures reliable removal of moisture. For accelerated cooling, the furnace is automatically opened step by step under program control. Depending on the batch used and the saggars, these high-temperature furnaces can achieve total cycle times of less than two and a half hours. The furnaces can be individually programmed for all recommended sintering curves of all zirconia manufacturers.

Specifications

  • Tmax 1650  °C
  • High-quality heating elements made of molybdenum disilicide offer very good protection against chemical interaction between charge and heating elements
  • Appealing, double-walled stainless steel housing
  • Outstanding temperature uniformity due to all-round furnace chamber heating
  • Precise, motorized toothed belt drive of the table with button operation
  • Forced cooling function with automatic, step-by-step opening from a preset temperature
  • Exhaust air vent in the roof
  • Drying function: When starting the program the table will be driven in drying position and closes automatically at 500 °C
