HEATING ELEMENT TEMPERATURE CONTROL SYSTEM

摘要

A temperature control system for heating element, provided in injection moulding machines, which by integrating the electronics on the heating elements themselves allows an efficient decentralised resistor temperature control, reducing the manufacturing costs of the system itself. It avoids, for example, the use of costly high-temperature resistant wires. The control system of the invention is very simple to assemble and further allows to reduce the maintenance costs and the duration of the machine downtimes.
