High Density 3mm Diameter Mini Cartridge Heater for Molding Heating  

Descriptions:

Cartridge heater  is cylindrical electrical heating elements. Protected with a stainless steel sheath, their  watt density can reach 25 W/cm2 and their operating temperature   can go up to 800°C (1472°F).

Mostly cartridge heater is used for heating up solids such as injection presses heating plates or various tools, cartridge heater  can also be used for heating up water of gases under certain conditions.

Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc .

Cartridge heaters are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries

Various cartridge heater technologies are available. The choice of technology will depend on technical specifications required and the application. Unless you know exactly which product you are looking for,  we will recommend you the best solution for your needs.
