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.

J3(DC24V Pneumatic), J1(AC110V, AC220V)).
(Factory setting : AC220V)
* Output Voltage must be same with Solenoid Valve Input Voltage in mold.
( Unless, it causes malfunction in operation)
*Note : Sequence timer controller Unit card is interchangeable without regard
for Pneumatic or Hydraulic, but the Controller case has to be fit in
according to a type.

YUDO Sequence Timer( TW 600 ) has 3 types of MODE.
The user can adjust Gate open/close/delay time for the optimal injection
application in a convenient way.
1) MODE A
Selection Mode A - After the injection signal has been received,
the gate remains closed during the DEL time. After the Del time
has elapsed, the gate Opens and remains open until the end of the
injection signal.
Ex1 ) Injection time : 10 seconds DEL Time ( T1) : 3 second setting
Operation : Gate opens 3 seconds after receiving the injection signal,
and remains open for 7 seconds, and then closes.
2) MODE B
Selecting Mode B - After the injection signal has been received,
the gate remains Closed during the Del time.
After the Del time has elapsed, the gate Opens for the Open time setting
After the Open time has elapsed, the gate closes and remains closed.
Ex1 ) Injection time : 10 seconds / DEL Time : 3 second setting
/ Open time : 4 second setting
Operation : Gate opens 3 seconds after receiving the injection signal,
and remains in the open condition for 4 seconds,
and then closes.
Ex2) Injection time : 10 seconds. / Del Time : 3 seconds
/ Open time : 9 seconds.
Operation : After 3 seconds delay, the Gate opens 7 seconds after
receiving the injection signal, and then closes.
*Note : The gate closes as soon as the injection signal ends,
regardless of Open time setting Value.
3) MODE C
In MODE C, Users can carry out MODE B operation twice successively.
Ex1 ) Injection time : 20 seconds.
The first Del. time : 3 seconds / The first Open time : 4 seconds
The second Del. Time : 5 seconds / The second Open time : 6 seconds
Operation : After 3 sec. delay, the Gate opens for 4 seconds.
Successively after 5 sec. close, the Gate opens for 6 seconds.
4) Injection signal extension function
Generally a valve Gate closes, when injection signal ends. But in some cases,
the valve Gate should be kept open even though the injection signal ends.
Users can actualize this operation by setting MODE B with (-) open time.
Then the Timer controller itself keeps the injection signal in an open condition.
This function is specially used for controlling Extension Nozzle in Stack-mold
which needs to make a Gate close after HRS inner channel pressure becomes
reduced enough.
Ex1 ) injection time : 10 sec. / Delay time : 3 sec. / Open time : (-) 2 sec.
Operation : Gate opens 3 seconds after receiving the injection signal,
and still remains in the open condition for 2 seconds after
injection signal ends.

1) MODE A application
(1) In case of short shot on product
Open Gate 1 first to enlarge filling area, then Open Gate 2 later to fill up well.
(2) To inject products which have a big dimensional difference per cavity,
open G1 first to fill up the big size and then open G2 later to make
the balance. It can optimize the injection precision.
2) MODE B application
(1) To inject complicated products which have a big dimensional difference,
apply MODE 1 for Gate 1~4, and MODE B only for Gate 5. It is used to
fill up the very small sized dimension just before the injection ends.
3) MODE C application
(1) It is used to apply 'one and after' injection signal control.
Opening the gates first which could have fill-up Unbalance if Users
open the all gates at the same time, and then close the gates keeping
time with fill up. It is designed to avoid the excessive filling pressure.
Although this is also possible in MODE B operation, the function to
keep up the holding pressure in channel by opening the Gate (The Timer
controller itself keeps the injection signal in an open condition )
is possible only in MODE C. MODE C is a new type of output pattern
which is able to optimize the various sequence controls to match the
product feature and injection peculiarity.
