National Plastic Heater continues to support round coil heaters, that revolutionized the injection molding industry in 1980, for nozzle heating applications. The compaction and flexibility of the round coil heaters are core attributes of this time proven technology. Emerging applications of the round coil heater include pressed in brass for nozzle heating and form in place for plate heating and three dimensional heating.

NPH round coil heaters are available in 3.0mm, 3.18mm, 3.2mm, and 4.0mm diameter sizes.

For coil heaters directly on the nozzle or with an outer diameter sheath National Plastic Heater recommends next generation flat coil heater technology.
