Investing
Investing is carried out using either IPS PressVEST (e.g. overnight) or IPS PressVEST Speed. For that purpose, the IPS Silicone
Ring with the matching investment ring gauge is used. Determine the precise wax weight as follows:
– Weigh the ring base (seal the opening of the ring base with wax).
– Position the objects to be pressed on the ring base and attach them with wax. Weigh again.
– The wax weight is calculated by deducting the weight of the ring base and the weight of the framework (including
opaquer) from the total weight.
Please refer to the Instructions for Use of the corresponding investment material for the detailed processing parameters.
The following procedure is recommended:
– Do not use a debubblizer on the wax objects. Remove separator thoroughly with oil-free compressed air.
– Mix the investment material. The investment material contains quartz powder. Therefore, avoid the inhalation of dust.
– Use a suitable instrument for the fine investment of the cavity. Make sure that the delicate wax margins are not dam-
aged.
– Carefully place the IPS Silicone Ring on the ring base without damaging the wax objects. The silicone ring must sit flush
on the investment ring base.
– Subsequently, carefully fill the investment ring with investment material up to the marking and position the ring gauge
with a hinged movement.
– Allow the investment ring to set without manipulating it.
– Do not use IPS PressVEST for investment over the weekend to prevent crystallization.
