Injection mold hot runner system from the hot runner system.
Usually, the nozzle may not always be installed in plate, can also be empty on the nozzle flange, but this kind of system needs to be fixed plate to maintain the system of oneness.
For the majority of plastic processing, due to the temperature of the injection mould is close to 200 degrees, so the hot runner and the temperature difference exists between the injection mold.
If the system is connected on the mould plate, will raise the temperature and the heat loss of the increase, and the shunt flow between the plate and the nozzle may also have blind Angle.
when hot runner need maintenance, hot runner must be completely removed from the injection mold. Because the nozzle is not connected to the board, electric and hydraulic circuit must be fully open, and at the end of the maintenance to connect again.
