HASCO hot runner 7
3 Structure and functionality
3.1 General information
The H1280 hot-runner controllers are especially suited to the temperature control of hot runner moulds on injection
moulding machines. In use, the controllers are connected directly to the mould via cables.
During operation, the hot runner controllers deliver electric current to the heating units for an injection mould. The so-
called heating current leads to an adjustable temperature increase in the heating units and hence in the mould.
Continuous temperature monitoring takes place in parallel via connected thermocouples. In the event of deviations
between the actual temperature recorded and the temperature set on the hot runner controller, the heating current is
automatically adjusted until the two temperatures are identical.
The controllers are available in different variants. These differ solely in terms of the number of control circuits that are
possible – which are also referred to as heating zones. Depending on the variant, hot runner controllers are available
with either 6, 12, 18, 24 or 36 heating zones.
3.2 Structure
A 12-zone controller is shown by way of example in the figures that follow. All the designated components are identical
on controllers with more than 12 heating zones.
