Have you got the question about the mold wiring, while buying the hot runner controllers?
As you know, hot runner temperature controllers are control systems that continuously monitor the temperature of the assembly components. The systems can be controlled entirely centrally by a mainframe or used localized control modules to provide real-time, dedicated management of the hot runner assemblies. Internal thermocouple, heater wires should be exactly the same to the mold. And corresponds to the nozzles on the mold one by one. Otherwise, it may cause customers’ loss and production stopped by thermocouple, heater inversed.
Hope this post could help you understand the different kinds of wiring configurations.
Below are some wiring diagrams for hot runner controllers 15Amps, which widely used in injection molding equipment. (Other special wiring requests, should confirm with the suppliers before ordering)
