The fi gures given by our research and development department are guidelines and can be individually adjusted.
u To achieve higher levels of expansion we recommend using Investment Special BS Liquid 3.
Stirring
Use a spatula to stir the investment material by hand until the powder has been wetted thoroughly.
u Mixing in vacuum
60 seconds
Place in vacuum for 15 seconds but without switching the paddles on. Mix for 60 seconds. Check the
vacuum/paddles frequently for correct functioning. Inadequate vacuum results in inaccurate fi t and
bubbles on the casting.
Working time
Approx. 5–6 min. at ap-prox. 22°C (Room temp.)
The working time depends on the room temperature. Warmth curtails the working time.
Steel ring:
X1 / X3 / X6 / X9
Ringless:
X1 / X3 / X6
Investing
Fill the ring with investment: only use a vibrator if it is required to improve the fl ow. Avoid high vibra-
tion! This will lead to the formation of bubbles and breakdown of the mixture.
Placing the rings in a preheated furnace
20 minutes after start of mix. Roughen the top of the mould before placing it in the furnace!
