Pressing
Before the preheating cycle for the investment ring has ended, the following preparations for pressing must be carried out:
– Switch on the press furnace in time to ensure that the self-test and preheating phase are completed.
– Select the press program for IPS Empress Esthetic and the respective investment ring size (EP 600/EP 600 Combi).
– Place the ingots and AlOx plungers in the investment ring and position it quickly (in less than 1 min.) in the furnace.
– Do not use the IPS e.max AlOx Plunger Separator. The press temperature of the IPS Empress Esthetic ingots of 1075 °C/
1967 °F is too high for the separator to be effective.
Once the preheating cycle has been completed, remove the investment ring from the preheating furnace and proceed as
follows:
– Place the hot IPS Empress Esthetic ingot – in the required shade of the tooth (see material combination table) – into the
hot investment ring.
– Place the hot AlOx plunger into the hot investment ring.
– Place the completed investment ring central the hot press furnace.
– Press START to start the selected program.
