CMME Footprint Charging Generator
The CMME is a small profile footprint charging generator specially designed for IML
applications. The unit has fully integrated high voltage parts and only needs a 24V DC
supply. The housing is compact, robust and only weighs 500 grams which makes it perfect
for end of arm mounting in IML pick and placehandling systems. It can easily withstand
the high G-forces occurring during the IML process.
The CMME has a unique (patented) cyle OK feature.
A signal will become active when the label(s) have accumulated enough
electrostatic charge indicating that the charging is finished. This signal can be used
by the machine interface to decide to stop charging. A second stage in the cycle OK signal
will indicate that the charge on the mandrell has dropped below asafe level to start moving
the mandrell out of the mould.This innovative feature completely eliminates the guess work
and experimental setup for each individualIML application, and when changing product or label.
The best part is; It will save you money!Using the parameters generated by the
CMME you can drastically reduce the charging time and thus thetotal cycle time of the injection
moulding process.
- Speed up initial set up
- Speed up changeover
- Speed up cycle time
- Increase reliability
The cycle OK signal even gives you more information about the process. If during the charging
processthe charging level deviates more than 10% from the setpoint, the cycle OK signal will
notbe activated, telling you that charging was not successful. This could mean one or more of
thelabels are not present, causing too much voltage leakage.
Indication LED’s on both sides of the end of the CMME unit will display general information
about the status of the unit.

The CMME is equipped with an easily detachable high voltage distribution block. The high voltage distribution block is available with 1-8 connection cables.
The CMME can be used directly from a machine interface capable of supplying a 4-20 mA signal for the setpoint and a 24V DC signal for remote on/off.
Manual operation can be implemented by an additional control circuit. The control circuit enables you to mount a potentiometer and LED by simply providing 2 holes in the front panel of your machine interface.
