Hot runner system
1. hot runner wiring layout should be reasonable, easy for maintenance, wiring number should correspond one by one.
2. Hot runner should be tested for safety, insulation resistance to ground is more than 2MW.
3. temperature control cabinet and hot nozzle, hot runner should be used standard parts.
4. The main flow port sleeve is connected to the hot runner with threads, and the bottom surface plane contact is sealed.
5. The hot runner is in good contact with the heating plate or heating rod, and the heating plate is fixed with screws or studs, and the surface is well laminated.
6. J-type thermocouple should be used and matched with the temperature control table.
7. each group of heating elements should have thermocouple control, thermocouple position is reasonably arranged.
8. nozzle should meet the design requirements.
9. the hot runner should have reliable positioning, at least two positioning pins, or add screws to fix.
10. there should be heat insulation pad between the hot runner and the template.
11 temperature control table set temperature and the actual display temperature error should be less than ± 5 ° C, and temperature control sensitive.
12. the cavity and nozzle installation holes should be penetrated.
13. hot runner wiring should be bundled and covered with pressure plate.
14. there are two sockets of the same size, should be clearly marked.
15. The control line should be sheathed and undamaged.
16. the temperature control cabinet structure is reliable, no loose screws.
17. The socket is installed on the bakelite board and cannot exceed the maximum size of the template.
18. the electric wire is not allowed to be exposed outside the mold.
19. hot runner or template all contact with the wire should be rounded transition.
20. before the template assembly, all lines are free of broken short-circuit phenomenon. 21.
21. all wiring should be properly connected and well insulated.
22. After the template is installed and clamped, all wiring should be checked again with a multimeter.
