High-expansion speed investment, individually controllable for all alloys (except titanium).
Advantages: Casting ring can be placed into the furnace at final temperature (950 °C / 1742 °F) for speed preheating or preheated in stages overnight.
Used for all alloy groups.
The high overall expansion provides precision of fit long working times and a very creamy mixing consistency.
Castings with extremely smooth surfaces ensure uniform quality and exact reproduction of the pattern.
