Abstract

The new electrical heating element described here is for industrial use, especially for heating hot channel nozzles for pressure injection moulding. It comprises an electrical heater embedded in a metal of high thermal conductivity. The side of the heater away from the material to be heated, is preferably covered by thermal insulation. A thermocouple (5) is embedded in the metal and used to control the heater. In this new design, the thermocouple junction (6), i.e. its point of measurement, is surrounded by poorly-conducting material (7). This causes a sluggish thermocouple response. Preferably the junction is part-surrounded by stainless steel.
