High-Performance Industrial Coil Heaters

Coil heaters, also known as cable heaters, are highly versatile and compact thermal elements designed to deliver intense, concentrated heat in confined spaces. Engineered from premium nickel-chrome resistance wire placed inside a durable metal tube and filled with highly compacted magnesium oxide (MgO), these heaters are specially annealed to acquire extreme malleability. This allows them to be expertly bent into precise spiral or custom shapes, making them the industry standard for tightly wrapping around cylindrical nozzles and manifolds to ensure flawless heat transfer in plastic injection molding.
