3D Printer Cartridge Heater electric heater
1. Working Principle
Electric cartridge heater, also known as single-end tubular heater, one end can heat, another end is cold end. It is made of a metal tube put into the resistance alloy wire as the heating materials, the alloy wire is filled with good insulation high purity magnesium oxide as filler, the product has a big power, high thermal efficiency, fast heat dissipation characteristics.
2. Characteristics
Long life use
Equalized heat distribution
diameter and length control precision
high temperature resistance
bending wire characteristics
Flexible wire (bending resistance )
