The Right Thermal Solution For You
Coil heaters are 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 hot runner 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.
Applications
- Plastic Injection Molding
A Nexthermal coil heater’s strength is its ability to be shaped specifically for your nozzle heating applications. The heat can be directed to specific sections of the nozzle by adjusting the winding tightness in different sections. - Mass Spectrometry
Nexthermal coil heaters are used in a broad range of scientific and medical applications. Small and light-weight coil heaters can be used to change liquid samples into vapor. - Food / Tray Seal Packaging
Our coil heaters generate heat evenly along the heater, perfect for creating even seals in any type of tray sealing application including non-standard shapes. - Rubber Injection Molding
Nexthermal can manufacture round coil heaters to be fitted into a plate used for rubber injection molding. In some cases, we have even designed the plate to gain optimal performance and energy efficiency from the heater, resulting in a longer heater life and faster throughput.
Nexthermal coil heaters
- Range from Micro, Mini to Maxi Coil heaters so you can choose the right size and wattage capability for your application
- Includes internal thermocouple options or may be used with external thermocouples
- May be wound to directly fit a nozzle, embedded in a thermal mass for nozzle, formed into a grove for three dimensional heating, or can work as an easy-to-remove cartridge heater alternative
- May be manufactured with longer cold sections to allow higher temperature applications to utilize flexible leads and moisture resistance
