MULTICAST |
|
Multicast is a modified, superfine ground
α-hemihydrate
with an extraordinarily high specific surface quality.
By mixing Multicast with the locally available natural gypsum at
a corresponding mixing ratio, a moulding plaster is produced for
non-pressure casting with improved utilisation properties in
production as well as moulding plaster for roller moulding
applications. |

WORKING INSTRUCTIONS |
|
The mixing ratio of the powder component Multicast and local
natural gypsum should be selected as follows depending on the
quality of the natural gypsum. |
|
Mixing ratio - Multicast : Local natural gypsum |
40 : 60 or 50 : 50 |
|
Mixing ratio - Water : Gypsum |
1 : 1.75 - 1.85 |
|
First strew the local plaster, than Multicast into the water.
After a short soaking time, start mixing. |
|
Mixing time |
2.5 - 3 minutes |
|

Advantages:
-
Increased mechanical strength.
-
Improved absorption rate (fragment forming time).
-
Increased mould removal strength.
-
Slightly shorter casting cycles.
-
2 times higher casting cycles and increased mould life
thanks to reduced mould wear.
-
Reduced plaster mould production.
-
Reduced production downtimes due to fewer mould change
operations.
-
Reduced labour costs for mould casting and mould change
operations.
-
Lower disposal costs for used moulds.
|
A convection drying facility would be of advantage to avoid high
humidity at the mould casing location!
