Pressing
Carry out the following preparatory steps for pressing before the preheating cycle for the investment ring
has been completed:
– Switch on and preheat the press furnace in time.
– Select the press program for IPS e.max ZirPress in accordance with the investment ring size used.
– Prepare the cold IPS Alox Plunger or cold IPS One-Way Plunger 300 g.
– Dip the cold IPS Alox Plunger into the opening of the IPS Alox Plunger Separator.
– Prepare the cold IPS e.max ZirPress ingot(s) in the required shade.
Remove the investment ring from the preheating furnace immediately after completion of the preheating cycle.
This step may take 1 minute at most to prevent the investment ring from cooling down too much.
– Place the cold IPS e.max ZirPress ingot into the hot investment ring.
– Insert the ingots in the investment ring with the non-imprinted side facing down. The imprinted side faces up to check
the ingot shade. Use the IPS Ingot Tongs to load the 300 g investment system.
– Place the powder-coated side of the cold IPS Alox Plunger or the IPS One-Way Plunger 300 g into the hot investment
ring.
– Place the completed investment ring in the center of the hot press furnace.
– The selected press program is started by pressing START.
After the end of the press cycle (optical and/or acoustic signal), proceed as follows:
– Remove the investment ring from the press furnace using the investment ring tongs immediately after pressing.
– Place the investment ring on a cooling grid to cool in a place protected from draft.
– Do not speed up cooling, e.g. by blasting with compressed air
