A cartridge heater is a cylindrical heating element designed to be inserted into a hole or cavity in a metal block, mold, or other object to provide localized and efficient heating. These heaters are widely used in industrial applications, such as plastic molding, packaging, and fluid heating, due to their compact size, high power density, and ability to deliver precise and uniform heat.| Resistance heating wire | NiCr 80/20 wire |
