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. Place the nozzles into its housing. If there are sliding bushes they must be placed in position in the mold
before the nozzle. Attention to the position pegs, when applicable.
4. Place the crush CU rings (when applicable). These rings are a security element, the system can function
without them. Considering that the dimensional template and the system is correct, and there is no process of
regulations out of considered in the project, these are not necessary.
5. Assemble the locating pins in the housing. The central positioning pin and anti-rotation pin. The central part
spiking a ring spacer riding in and pin where the manifold will seat on.
6. Place the manifold in position. The correct position is set by the central pin position combined with the pin
anti rotation.
- The manifold has threaded holes for fixing eyebolts. These holes are some of the manifold fixing holes.
- The manifold should slide easily to settle on the "head" of the nozzles. If it does not, do not use force.
Remove and check the cause.
7. Move aside of dangerous areas all electrical cables to avoid crushing them.
8. After positioning the electrical cables check if they are all in good condition.
9. Tighten the screws on the manifold in a progressive and balanced manner. See tightening torque of the
screws in Appendix 1
10. Check that the manifold is parallel to the bottom plan of the housing. If not, disassemble and determine
the cause. It could be the manifold grip that is not balanced, or another reason to check.
11. Identify properly and clearly all the wires for proper identification at any time.
12. Follow the system electrical areas numbering according to the design, also visible on the ID Card.
13. Put the Pin guide ring in position (Only in valve gate systems).
14. Place the sliding plate reinforcement supports (when applicable).
15. Fit the sliding plate with particular attention to the electrical wires.
16. Tighten the plate in a balanced way.
- Ensure good and complete cleaning of the drive circuit of the cylinders in the sliding plate. Often the
appearance of metal chips or Teflon does not allow the smooth functioning of the system.
17. Check the independence and sealing of the circuits in accordance with the established in the project and
in accordance with the intended operation of the valve gate system.
18. With a multimeter, verify that all resistance wires are not giving electrical current to the mold.
19. Assembly the cylinders, with particular care not to damage the seals (only in valve gate systems).
20. Enter the valve pins checking the correct position. The valve pins should come easily when the system
has no plastic inside the channels. If it is difficult, check the cause (only in valve gate systems).
21. Close the cylinder cover by tightening the screws (only in valve gate systems).
22. Assembly the sequential operation manifold according to project drawing (only for sequential valve gate
systems).
23. Assembly the centering ring. Tighten in a balanced way. The centering ring has to adjust the system as
shown in the draft of the injection system.
24. Connect the wires taking into account:
- Wires should have only sufficient and required length that allows easy opening of the electrical box cover
and checking connections.
- Wires should consider connecting terminals appropriate to your connection plug. The not use, or partial use
of terminals can lead to system malfunction.
