Sintering
After the holding time, the furnace opens at 1,580 °C (2,876 °F) and then
cools down to 1,000 °C (1,832 °F) by itself. 1 minute before the door
opens, the furnace displays a "countdown" of 60 seconds.
At 1,000 °C (1,832 °F), the display starts to flash. This is followed by an
acoustic signal which repeats every 15 seconds. The signals are to
indicate that the sinter may be removed.
Unloading the furnace at 1000°C
1. Lift the crucible from the furnace door using the crucible fork and
place it on the fire-proof resting cube supplied with the device.
2. Press the start/stop button to close the furnace door. This helps retain
residual heat to shorten the heating-up phase if the program is to be
repeated.
 If you do not press the start/stop button after removing the
crucible from the furnace door, the furnace door will close
automatically after 5 minutes.
3. Wait 2 minutes.
4. Place the Superspeed covering on the fireproof tray using a pair of
tweezers.
5. After 2 minutes retention time, place the object being sintered on the
fireproof tray using a pair of tweezers.
6. Wait a further 2 minutes. Afterwards, the sinter is cooled down to the
extent that you can touch it without risk of burns.
6.4.2 Speed sintering (program starts at room temperature, no
pre-heating required)
This operating mode uses the speed sintering tray provided. Stacking the
sintering trays is not permitted in this sintering program. As described in
the "Practical use [ → 19]" section, the sintering tray is loaded with
sintering beads and inserted into the furnace using the speed crucible
fork. For more information, please refer to "Practical use [ → 19]".
