Electric Heating Element Coil Spring Heater for Hot Runner System
Our Hot Runner Coil Heaters are the epitome of engineering excellence, meticulously crafted from premium nickel-chrome resistance wire, carefully encased within a sturdy chrome-nickel steel tube. These elements are packed with high-grade MgO powder, ensuring unmatched heat transfer efficiency. Annealed to perfection, these heaters boast the flexibility needed for custom bending into any shape imaginable. Moreover, we offer hot runner heaters integrated with precise thermocouples. Our hot runner bushes feature a variety of heater cross-sections, coupled with a durable inner brass and an outer stainless steel cover.
Coil heatersRenowned as cable heaters, these elements can be masterfully crafted into a vast array of shapes, catering to diverse application demands. Typically, coil heaters are engineered as compact, high-efficiency nozzle heaters, fully annealed for peak performance.
Coil heaters are vital components on injection molding machine nozzles and sprue bushings, delivering comprehensive 360° heat coverage. For specialized heating needs, optional distributed wattage models are available.
Coil heaters also excel as adaptable cartridge heaters for uniquely sized bores. A straight, round cable heater can effortlessly thread through a sealing bar in packaging equipment setups.
