hot runner heaters, also known as cable heaters, can be made into various shapes according to their various applications. However hot runner heaters are often configured as small diameter, high-performance nozzle heaters,
Introduction to the hot runner heaters
A hot runner coil heater is a tubular heating element made of a nickel-chromium resistance wire in a chrome-nickel steel tube filled with MgO powder. These hot runner heaters can be made into round sections and different shapes.
