Checking the sprueing
The IPS Sprue Guide will help you to easily check the correct sprueing of the objects to be pressed on
the investment ring base. By turning the IPS Sprue Guide on the investment ring base, the required
distance to the silicone ring, the proper height, as well as the sprueing angle can be quickly checked.
The distance between the wax patterns to be pressed and the IPS Silicone Ring/ring gauge
must be at least 10 mm. This applies to all the above diagrams.
