Investing­

Investing is carried out with either IPS PressVEST or IPS PressVEST Speed. The corresponding IPS Silicone Ring with the 
matching ring gauge is used for investment. 
Determine the weight of the object before investing.
–  Position the wax objects on the ring base and attach them with wax and weigh.
–  The difference between the empty and the loaded ring base is the definitive wax weight.

Please refer to the Instructions for Use of the corresponding investment material regarding the detailed processing  
parameters. The following basic procedure is recommended:
–  Do not use a debubblizer on the wax objects.
–  Carefully place the IPS Silicone Ring on the ring base without damaging the objects. The silicone ring must sit flush on 

the ring base.

–  The processing temperature of the investment material is 18– max. 23 °C / 64 °F – max. 73 °F. Higher or lower  

processing temperatures substantially affect the setting behaviour.

–  Mix the investment material. Note: The investment material contains quartz powder. Therefore, avoid the inhalation of 

dust.

carefully­apply­additional­investment­material­to­the­screw­channel­from­the­top.

–  Carefully fill the investment ring with investment material up to the marking on the silicone ring and position the ring 

gauge with a hinged movement.

–  Allow the investment ring to set without manipulating it.
–  To prevent crystallization of the IPS PressVEST investment material, the invested ring must be processed within 24 hours.
–  If IPS PressVest Speed is used, make sure that the investment ring is placed in the preheating furnace after a setting time 

of at least 30 and maximum 45 minutes.

Liquid­concentration: The data contained in the table are approximative values. Depending on the geometry of the Ti 
base and the materials used for the wax-up, these values may be individually changed. However, the concentrated Liquid 
content must not be lower than 50% in relation to distilled water.
Important: The total quantity of liquid (Liquid + dist. water) must not be altered.
