Double tablets
Previous tablet did not eject correctly.
Remove the double tablet manually
from the Die bore.
Excess granular materials were
placed in the Die, which prevented
the ejection of the existing tablet.
Clean the Tooling to remove any
excess granular materials and make
sure that it is clean and completely
dry.
Cracked or broken tablets
There are problems with the
formulation of the granules and
ingredients.
If the machine is able to make tablets
with LFA's Firmapress®, then the
problem is your mix. Adjust your
formulation. If still an issue, contact
LFA for support.
The Force Feeder is not feeding
enough material to be pressed in
tablet form.
Adjust the Force Feeder, Take-Off
Blade, and Scraper accordingly.
