Precautions for the Design and Use of Cartridge Heaters

Cartridge Heaters are used in plastic packaging, small mold heating, injection molding machine hot nozzle heating, hot press molding machinery, cigarette machinery, semiconductor eutectic welding, die casting input channel heating, runnerless injection, and various gas expansion. Equipment heating such as cold effect. There is still a lot of knowledge about Cartridge Heaters. The following electric heating tube manufacturers introduce the design and use of single-head electric heating tubes and the requirements for internal heating wires.

Precautions for the Design and Use of Cartridge Heaters

(1) Efforts should be made to narrow the gap between the outer diameter of the single-head electric heating tube of the mold and its insertion hole diameter. Usually the gap between the two is less than 0.1-0.2mm. .

(2) When machining the mounting hole, the coaxiality and size tolerance should be effectively ensured. For example, use a reamer and other tools to trim the machining.

(3) Before installing the heating pipe, the residue left in the processing, such as organic oil, will be carbonized after heating, which will affect the heat transfer ability.

(4) The solar electric heating tube adopts a low power density design and a special anti-scale treatment method, which greatly enhances the service life of the solar electric heating tube. Generally, it is made of stainless steel 316 or higher, which is very corrosion-resistant and can be cleaned. Increase service life.

There is no problem when using at the design voltage. The actual power during use can be calculated according to the following formula: [Use voltage/design voltage]*[Use voltage/design voltage]*Design i power = power during use (example) Electric heating tube with rated voltage and power of 230V and 500W, using voltage of 220V, its operating power is 418.6W, which is about 84% of the rated power.
