The Manufacturing Process of Electric Heating Elements

The production of electric heating elements requires precision engineering and a deep understanding of materials and applications. Electric heating elements manufacturers, particularly those specializing in industrial cartridge heaters, follow a meticulous process to ensure high-quality products.

Key Steps in Manufacturing

1. Material Selection: High-grade materials like stainless steel, Incoloy, and Nichrome are chosen for their durability and resistance to high temperatures.


2. Winding the Brass Coil Heaters: A Nichrome wire is coiled to create the heating element. The resistance of the coil determines the heat output.


3. Insulation and Encapsulation: The coiled wire is surrounded by magnesium oxide powder, providing electrical insulation and thermal conductivity.


4. Assembly and Testing: The heater is enclosed in a metal sheath, sealed, and tested for performance.
