What is a Coil Heater?
Coil heaters, also referred to as cable heaters, hot runner nozzle heaters, spring heaters, hot sprue heater, or micro tubular heaters. Though often found in a spiraling or winding shape, a coil heater is not named after the shape of its exterior; the name refers to the resistance wire inside the heater that has a small winding pattern throughout the length of the heater.
Coil Heater Applications
- Plastic Injection Molding
- Mass Spectrometry
- Top Seal Packaging
- Food Production
Nexthermal Coil Heaters
- Range from Micro Mini to Maxi Coil heater so you can choose the right size and wattage capability for your application
- Have internal thermocouple options or could be used with external thermocouples
- Can be wound to directly fit a nozzle, embedded in a thermal mass for nozzle, formed into a grove for three dimensional heating, or would as an easy to remove cartridge heater alternative
- Can be manufactured with longer cold sections to allow higher temperature applications to utilize flexible leads and moisture resistance
