If you use squeeze pins, then you probably
from time to time have experienced sticking pins. This means you are
probably producing scrap.
The Mentium system can monitor up to 8-squeeze
pins in 4-cavities. We can capture the velocity and position displacement
of each pin, as well as the pressure supplied to each pin.
collected allows us to obtain the peak velocity, total displacement and
maximum pressure of each pin. Those values then become process variables
that can be used to segregate parts. If you have a multi-cavity die then we
can instruct the robot to only segregate the cavity/cavities where a squeeze
pin variable exceeded the alarm condition. Therefore, if itís a 4-cavity
die and only one cavity was affected then the robot would accept the other
3-cavites as good parts and only segregate the bad one rather than all
4-parts. This feature, allows for the reduction of scrap and provides you
with the option of fixing the pin right away, or to continue running the
machine and produce 3 good parts every shot, at a 75% yield.
