Investing
Investing is carried out using either IPS PressVEST (e.g. overnight) or IPS PressVEST Speed. The corresponding IPS Silicone Ring (100 g, 200 g,
300 g) with the matching IPS Ring Gauge is used for investment. Please refer to the Instructions for Use of the corresponding investment
material for the detailed processing parameters. If resin objects are invested, the conventional investment material should be preferred. The
use of the Speed version presents an increased risk of investment ring cracks.
The following procedure is recommended:
– Do not use a debubblizer on the wax objects.
– The processing temperature of the investment material is 18 – max. 23 °C (64–73°F). Higher or lower processing temperatures substantial-
ly affect the setting behaviour.
– Mix the investment material. Note: The investment material contains quartz powder. Therefore, avoid the inhalation of dust.
– Use a suitable instrument for the fine investment of the cavity (e.g. a small brush). Make sure that the delicate wax margins are not
damaged.
– Carefully place the IPS Silicone Ring on the ring base without damaging the wax objects. The silicone ring must sit flush on the ring base.
– Carefully fill the investment ring with investment material up to the marking on the IPS Silicone Ring. Make sure that no air is trapped in
the material.
– Position the ring gauge with a hinged movement.
– Allow the investment ring to set without manipulating it.
– The invested ring must be further processed after a setting time of 24 hours at the latest to prevent crystallization of the IPS Press VEST
investment material.
