mica band heaters

Mica Band Heaters are built in 'MICA' Insulation with 'L' type clamping and manufactured in M.S. Plated sheet or S.S. outer & Brass inner sheet. * These heaters are the most economic & widely used for heating of moulds, dies, nozzles and barrels on all types of plastic processing machinery. * Thin mica insulation provides excellent thermal conductivity by 'Conduction' and faster heating up and cooling down is possible. * Maximum sheath temperature upto 480 degree Celsius. * Maximum Watt density - 3 W/Sq cm to 3.5 W/Sq. cm. * Plate, Strip, square, rectangular shape mica band heaters can be manufactured as per customer specifications in one or two piece units. Spot welded clamp bars & Allen screw clamping can be done like Ceramic Band Heaters Application FOR PLASTIC INJECTION AND EXTRUSION MACHINES CONSTRUCTION : Design consists of Nichrome resistance rbbon proecisely wound, evenly spaced on a Inorganic Mica Sheets which eliminates hot spot. Our exclusive Computer Softwate designing maximize the element ribbon coverage of the heated area, which results in uniform heat distribution. The resistance ribbon is carefully selected considering all aspects in the application to obtain maximum life of the heater. This ribbon wound mica foemer and insulated with mica sheets, which is then covered with SS/Brass sheets. Specification and Tolerances : ELECTRICAL Wattage :5% Voltage : 230 Volts / 415 Volts. DIMENSIONAL Minimum Dia : 25mm Minimum Width : 20mm Width tolerance : 2mm Std. gap between Clamps : 5-8mm • Most Economical • Faster Heating up and Cooling Down possible APPLICATIONS These heaters are suitable to apply heat by conduction to cylindrical surfaces-Injection & Blow Molding M/cs, Extruders, Dies, Drum Heating.
