Shot Size
Shot Size
sets the quantity of plastic used during one machine cycle to produce a container. The setting
type is different depending on the accumulator or continuous machine type.
Accumulator Machines
– the amount of plastic extruded by the accumulator or accumulator stroke. Shot
Size
is shown as a percentage (or mm) of the accumulator stroke and its value may only be set between
1% and 100%.
Continuous Extrusion Machines
– the length of time for one machine cycle in seconds.
Cycle Time
may
only be set between 0.1 and 999.9 seconds. This time is started by machine event, such as the motion of
the knife cutting the parison.
An additional feature is
Auto Shot
which automatically sets
Shot Size
to be equal to the time interval
between sequential knife cuts. If
Auto Shot
is ON then
Shot Size
automatically update each cycle interval,
and
Shot Size
is no effect on the cycle time.
Die Gap
This parameter is the core gap target position when the die gap digital signal (TB-2-2) is input. Set the
core die gap opening amount on the cycle between the end of the program profile (point 200) and the start
of the next cycle. The setting range can be set between 0 and 100% with respect to the maximum value
of the core die gap opening amount. Also, if this parameter is changed while the [Die gap] status ([Die
gap] status indicator is green), the core gap changes at the speed of [Die gap slope] setting when pressing
the [SET] key Move to a setting position.
In general, [die gap] is used to control the thickness of the parison in a continuous blow molding machine
(for example, resin cutting etc.), in the accumulator molding machine to close the core gap and prevent
resin drooping during filling.
Delay
Delay
delays the start of the programmed profile after the machine cycle is started. During this
Delay
the
tooling die gap is maintained at the gap programmed by profile point 1.
Delay
may be set from 0% to
999.9% of the
Shot Size in ACC mode
. If Continuous Extrusion mode,
Delay
may be set from 0sec to
999.9sec
Delay
is often used to synchronize the position of the initial programmed portion (bottom) of the parison
with the bottom of the container mold.
Cushion
Cushion
applies to Accumulator Machines and when filling type selected to Extrusion only.
Cushion
is the point where the accumulator stopped with pushed out.
Cushion
is often set to leave a
small amount of material in the accumulator at the end of the push out to insure that the accumulator does
not bottom out before all of the plastic required for programmed portion of the parison is extruded.
As the total accumulator stroke has been made equal to a
Shot Size
setting of 100%, the total of the
equation
Shot Size + Shot Size x Delay
+ Shot Size x Cushion
must be equal to or less than 100% of the actual maximum accumulator stroke.
Auto Cycle
Applicable only with continuous extrusion machines. It is not displayed on the accumulator type machine.
This parameter automatically sets [cycle time] to a value equal to the time interval between successive
start signals (TB-2-1). When [Auto cycle] is set to ON, [Cycle time] is automatically updated every interval
of each cycle.
