DENTSPLY Multimat 2 Touch+Press - Firing Parameter Limit Values

4 Practical application: introduction
4.1 Firing parameter limit values
56
Preheating
The firing chamber moves from the last drying position to the preheating position and the preheating time is displayed counting down to zero.
Time-controlled vacuum (Dentsply firing method)
After completion of the preheating time, the firing chamber closes; the vacuum chamber activates and evacuates the firing chamber until the
preset vacuum is reached.
Temperature-controlled vacuum (Dentsply Ceramco firing method)
Vacuum activation and deactivation is temperature-controlled.
Heating rate
Once the preset vacuum is reached, the temperature increases with the preset heating rate to the firing temperature. Below the program sec-
tion, the heating time is displayed, counting down to zero.
Vacuum time
After reaching the firing temperature, the firing time under vacuum starts. Below the program section, the vacuum time is displayed, counting
down to zero. At the end of the vacuum time, the firing chamber is ventilated.
Firing time
The vacuum time is followed by the firing time at normal pres sure, i.e. without vacuum. Below the program section, the firing time is displayed,
counting down to zero.
Note:
When heating the firing chamber, there may be vibration noises from the heater winding.
Tempering (not programmed in the test program)
The tempering position of 50 mm is a factory-preset value. For other metal ceramics, ask the ceramics manufacturer for the values for tempe-
ring position and tempering temperature (see also section 6.14).
Cooling stage (not programmed in the test program)
(See section
5.5.12)
* Temperature-controlled vacuum is only selectable in the Ceramco firing method
Note: Values outside of these limits can neither be set nor started. The entered value is set back automatically to the previous value.
