Nozzle Cast-in Heaters
• Homogenious heat transfer
• Full surface contact with the heating element
• Longer life
• Heat absorption
• Precise heat control
• Energy Saving (longer on/off intervals

Why cast-in nozzle heaters instead of conventional coil heaters?

Coil heaters may seem as a sufficient and relatively cheaper solution for nozzles.
However, there are some crucial disadvantages of conventional coil heaters.
Coil heaters are;
• Expanding in diameter, when heated
• Partially contacting the surface of the nozzle
• Because of its low mass, it heat losses are very high
• More than half of the heater surface does not touch anywhere due to its cross section
• Due to heat losses, it is not possible to keep the desired temperature during injection
• Frequent on/off intervals
Cast-in Nozzle heaters does not have these disadvantages.
Ultimately, its expected life time is 3 times more than a conventional coil heater.
Full surface contact prevents the cool-down of the plastic during the injection.
Because of its relatively higher mass, it absorbs and contains the heat for a long time. Therefore, it is possible to keep the desired temperature anytime.
Also on/off intervals are longer which extends the life time of the heater.
We strongly recommend cast-in nozzle heaters for high temperature plastics.
