Installation
1. Make the dimensional housing verification with special care for the tight tolerance fitting zones and system
seating dimensions according to the CAD file information. In case of doubt or unclear information contact
YUDO.
2. Make sure the housing is in proper conditions to receive the hot runner and in correct position to proceed
with assembling without risks for people and equipment.
3. Assemble pin anti rotation in the mold. The central spiking should be attached to the Manifold.
4. Identify in the system the different placement points of the eyebolts and search for the combination that
allows raising the balanced system, keeping the manifold horizontally or close to. On systems that do not
allow the placement of eyebolts, it is recommended to use straps or magnetic.
5. Place lubricant grease on the tips of the nozzles and adjust zones in diameter, particularly H7 and H6
fit.
6. Place lubricant grease
on nozzle bushes (nozzle attachment bushings)
7. Install the manifold in place. The correct position is set by the central pin position combined with the pin anti
rotation.
8. Lower the system into the housing with the nozzles pointed to respective housings. If there are sliding
bushes they must be placed in position in the mold before the nozzles.
9. These systems are assembled in a cold temperature.
10. Lower the system to the housing and check that the manifold is in its correct position. The correct position
is defined by the central pin position combined with the anti-rotation pin.
The system is expected to fall easily until settle the supports. If not, do not use force. Relieve the nozzle
screws in a turn (360°). Then again bring down the system to its position in the mold. If there is any difficulty
may be used a Teflon mallet, beating with moderate force in the manifold supports.
11. After the system is properly housed, re-tighten the screws nozzle with correct torque force - see
Appendix 1
Do it in a progressive and balanced manner.
(This is only necessary in the first assembly or after disassembly of the manifold nozzles)
12. Check that the manifold is parallel to the bottom plan of the housing. Otherwise,
disassemble and
determine the cause. It could be the manifold grip that is not balanced, or another reason to check.
13. Put in place the cylinder rings. Only for valve gate systems and when they are part of the system design.
14. Assemble the sliding plate with particular attention to interference with any system component.
15. Tighten the plate in a balanced way.
16. Assemble the centering ring. Tighten in a balanced way. The centering ring has to adjust the system as
shown in the injection system draft.
17. Plugs and their electrical connections must be kept away from contact with water oil or other liquids.
18. Plugs and their electrical box must be placed in order to be protected from stroke or other accidents that
may damage the set.
19. After finishing the assembly, check if there is no undue electrical current passage and if continuity is doing
in the right poles.
Normally thermocouples are not isolated.
20. Check the heating of the system: Heat the system up to 150 ° C, stabilize the temperature of all electrical
heating zones and keep heating for 10 minutes. Always use soft start (slow heating) up
to the temperature of
100 ° C.
21. Check the correct Valve Pins movement by activating the respective cylinders (Only for valve gate
systems).
22. Let the system cool down.
23. Keep the system in a place free of moisture, metal chips or under possible physical shocks. Other care
considered suitable will be important to keep the system in good working order.
YUDO provides hydraulic and pneumatic systems but each one only work correctly with the drive specified in
the project. Do not test pneumatic systems with oil or vice versa.
Any anomaly detected in the system must be reported to YUDO.
