Analysis and Explanation of Heating Element and Hot Runner System
Below is the analysis and explanation of the heating element and hot runner system for your check and reference. If you have any other questions, please feel free to contact us!
Name |
Analysis and Explanation |
| hot runner system | Heating the runner during injection to keep the plastic in the runner in a high-temperature molten state |
| steel O-ring | Used for sealing between the runner and the sprue bushing opening |
| hot manifold | Runner plate for installing heater cartridges, thermocouples, and hot nozzles |
| high temp. insulator sheet | Heat insulation plate (also called insulating plate) that prevents heat loss |
| riser pad | Spacer blocks that prevent heat transfer from the hot runner plate to the mold base |
| cernter support pad | Spacer blocks between the hot runner plate center and A-plate |
| valve gate system | The opening of hot nozzles is controlled by valves |
| sequential valve gate | Controlling the opening/closing of multiple hot nozzles through cylinder actuation, achieving ideal weld-line-free plastic parts |
| geater nozzle | Also called hot nozzle or heated nozzle |
| nozzle bush | The part of the hot nozzle contacting the cavity, serving to fix the heated nozzle |
| heater sprue gate | The part of the hot nozzle contacting the mold cavity |
| close pin | Valve pin in the hot nozzle for sealing plastic |
| close pin band | Guide bushing for the valve pin (also called pin guide bush (YUDO) or pin guide (DEM) |
| band heater | Also called heating coil or heater wire |
| heater sheet | Heating elements often installed on Mold Master hot runner plates |
| thermocouple | For temperature detection (also called temperature probe or thermocouple wire) |
| extend nozzle | Connected to the front end of hot nozzles to extend nozzle length |
| heater shell | Heating shell outside hot nozzles and runner plates (also called heating collar) |
| gate shell insulator | Insulating collar around hot nozzle exterior for heat insulation |
| manifold heater | Heating elements installed in the middle of runner plates (e.g., DME’s CHS series and ECH series) |
| heater puller | Installed at heater cartridge ends for sealing |
| end plug | Also called hot runner end plug |
| heater clamp | For encapsulating and securing heater cartridges |
| water cooled gate insert | Used for cooling hot nozzle tips (e.g., components provided by Mold Master) |
| back plate | Component installed on hot runner plates to mate with machine nozzles (without heating elements) |
| temp control module | Temperature control circuit board |
| main frame | Refers only to the housing/enclosure for temperature control components |
| terminal mounting box | Socket mounting bracket (also called power box) |
| power cable | Wiring between power supply and temperature control box |
| mold power-thermocouple | Temperature control and heating power wiring (only for connections between control box and mold) |
| power/signal adapter | Includes power connectors and thermocouple connectors |
| power/signal connector | Includes power sockets and thermocouple sockets |
| reflector sheet | Parts used in HASCO hot runner systems (Z1064..) |
| accessory kit | Assemblies used in HASCO hot runner systems (Z1067/…) |
| filter cartridge | Parts for HASCO hot nozzles (Z109/…) |
| heater plate | Components installed on the back of Mold Master hot runner plates for heating and temperature control |
| inlet extension | Components in Mold Master systems that mate with machine nozzles on runner plates (with heating elements) |
