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
