Classification of resistance heaters-heating coils

Heating coils are mainly used in heating barrels of plastic machinery. They are generally divided into ceramic heating coils and mica heating coils. For ceramic heating coils, the resistance wire is embedded in the talc module, and the talc module plays the role of insulation; for mica heating coils, the resistance wire is wound on the mica sheet, and the mica sheet plays the role of insulation; meanwhile, the nickel-chromium alloy plate surrounds the outside to play Protection and thermal conductivity.
