Warming pressure
= pressure needed to warm up the bottom film. After reaching the
“SP” the warming time will start.
Warming time
= time needed to warm up the film throughout. When the time has
passed the forming valve will open.
Forming pressure
= pressure needed to bring the heated film as fast as possible
down to the forming plate. After reaching the “SP” the film
cooling time will start.
Film cooling time
= time needed to cool down the film. The bottom die is cooled so
the heat can be transferred quickly to the forming plates until
the temperature is decreased by ~30°C to freeze the shape into
the film.
Ventilation pressure
= before we can open the die set, we need to balance the inside
and outside pressure by ventilating, here the pressure level for
opening can be set.
Ventilation time
= ventilation controlled by time.
Air pressure from below
*
= Compressed air from below to release the formed package out
of the forming chamber.
*Optional function!
