ABSTRACT:
In the construction of hot channel nozzles (21) very precise temperature control over the length of a nozzle channel is desirable. To achieve this, a nozzle tube (32) for accommodating the plastic melt is constructed as an electrical resistance heater over its entire length, i.e. up to the nozzle bore (33), and can accordingly be heated. The nozzle tube (32) has differing, namely adapted, heating power over its length as a result of appropriate construction over its length, so that a substantially uniform temperature of the plastic melt is achieved.
