Hot Runner Nozzle Heating Element Mica Insulated Copper Sheath Band Heaters

Hot Runner Nozzle Heating Element Mica Insulated Copper Sheath Band Heaters

1. Brief Introduction

Mica Band heaters are used in plastic processing industry for keeping the nozzles of injection molding machines hot. Nozzle heaters are manufactured from high quality mica sheet or ceramic, and have Nickel Chrome resistance. Nozzle heaters are covered by metal sheathing & can be rolled to the required shape. Band heaters operate efficiently when the sheath temperatures are kept below 280 degree centigrade. If this temperature is maintained, the life of the band heaters gets long.

2. Features:

High class Nickel Chrome ribbon is used.
Maximum power: 3w/cm2(s.steel),4.5w/cm2(brass),6.5w/cm2(ceramic insulation)
Operating temperature up maximum of 500 degree centigrade
Axial, Radial & Tangential terminals are available
Thermocouple holes can be provided as per client's requirements

4. Application

Band heaters are commonly used in the plastics industry: to heat plasticization cylinders, extruders and injection presses. They are also employed on woodworking machinery and scientific-medical equipment.

Flat mica bands are used in the packing trade (sealing bars and wheels), industrial ironing (mangles) and plastics (extrusion/blower machines).
