Mica Heater is a kind of heating element which adopts mica sheet as insulating substrate and combines with resistance wire. It has the features of small size, light weight, even heating, high temperature resistance, etc. It is widely used in injection molding machine tubes, extruder molds and other industrial heating fields. The mica heater generates heat through the resistance wire and transfers the heat to the mica sheet, which in turn distributes the heat uniformly to the heated objects, realizing efficient heating. With its simple structure and easy installation, it is one of the important equipments for industrial heating.
Mica heater utilizes the high temperature resistance and excellent insulation of mica material to produce uniform heat through electric current, which is widely used in industry, household appliances and experimental equipment. It has the advantages of high temperature resistance, good stability and uniform heating.
