cartridge heating mlement general information
A cartridge heater is a tube-shaped, heavy-duty, industrial joule heating element (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Highly compacted they reach a surface watt density of up to 30 w/cm².
It may be used to heat any kind of substance or material, such as oil, air, or sugar. However, a common application is plastic pellets, which are melted in order to form molded plastic parts. An example of such a process is the “hot runner” process. Cartridge heaters resemble tubular heaters structurally but tend to have higher watt densities.
