YUDO Sequence Injection System is to provide a means of controlling the mould
filling sequence when Valve Gate Hot Runner System. The sequence
injection Timer enables the Valve Gates of a Hot-Runner System to
be individually controlled to provide the following benefits.
1) Removal or Positioning of Weld Line
Quality of the Molded part can be improved by removing or
re-positioning of weld lines on visual surfaces, or sections where a
weld line would cause a weakness.
2) Regulation of the Injection Quantity by Gate operation
Injection balance can be adjusted in Family mould application.
3) Improvement on Flash and short-shot
By Gate open control in an orderly manner, it can eliminate Flash
and short-shot problem.

DELAY The time until gate is started to be opened
after receiving injection signal.
Mode A, Mode B, Mode C operates in the
same way. ( Basic setting value : 3 sec. )
OPEN The time when gate is being opened.
Counting continues in mode A until injection
signal ends. Gate opens only during setting
time in Mode B and Mode C.
( Basic setting value : 3 sec. )
SIGNAL LED Lamp is turned on, as injection signal is input.
OUT LED Lamp is turned on, as Gate is open.
In manual mode, it operates in the same way.
MODE A LED Lamp is turned on when it is set as A type
( Refer to 5-page, Mode setting )
MODE B LED Lamp is turned on when it is set as B type
( Refer to 5-page, Mode setting )
MODE C LED Lamp is turned on when it is set as B type
( Refer to 5-page, Mode setting )
DELAY SET Key
A key to set gate opening time after injection signal.
("SAVE" is displayed 3 seconds after setting, and
then setting value is saved. If signal is turned on
before "save" display, it operates with the
changed value. If input power is turned off and
then turned on, setting value is not saved).
UP Key
A key to set up tim by pressing DEL or
OPEN SET Key simultaneously .
DOWN Key
A key to turn down time setting by pressing
DEL or OPEN SET key simultaneously.
Manual Output Key
A Key to open Gate manually.
It operates only when the key is being pressed.
OPEN SET Key
A key to set the time when gate is being opened.
This is used by pressing key or key simultaneously.
( Save function is the same as DEL SET key )
