The total quantity of liquid (liquid + dist. water) must not be altered. The indications regarding the liquid

concen tration are approximates and may be adjusted, if required. Do not dilute the liquid to below 40%.

Processing

Excess of separating agents may cause reactions with the investment material and affect the press result.

Disperse excess with compressed air before investment.

– Fill liquid into the mixing cup.

– Add powder.

– Thoroughly mix the investment material with a spatula for 20 seconds until even wetting of the powder is

achieved.

Vacuum mixer

Vacuum mixing time (at room temperature) 2.5 min

Speed approx. 350 rpm

Processing time 6 – 7 min

Setting time min. 30 min – max. 45 min

The processing time depends on the material temperature, mixing quantity, mixing time and mixing intensity.

A higher material temperature and/or longer mixing time shortens the processing time.

Investment

– Mix max. 400 g of investment material in one go

– Closely observe the mixing ratio!

– Investment is carried out on a shaker under slight vibration. Allow the investment ring to set without

manipulating it.

Some aspects influencing the setting expansion of the investment material

– Temperature of the investment material and the liquid

– Residual water in the mixing cup, atmospheric humidity
