Coil Heaters For Hot Runners

Coil heaters, also known as cable heaters, are high-performance heating elements designed for precise and efficient heating in small spaces or on irregular surfaces. These heaters consist of a helical coil of resistance wire that is uniformly wound and encapsulated in a metal sheath, typically stainless steel or Inconel, for protection and durability.Coil heaters are commonly used in applications such as hot runner systems in injection molding, plastic extrusion, sealing bars, and medical equipment. They are valued for their rapid heat-up times, high watt densities, flexibility, and ability to deliver consistent and controlled heat. Their compact design allows for easy integration into complex heating assemblies, providing reliable and targeted heating solutions in demanding industrial environments.
