Description

The use of a cartridge heater begins with the point of insertion. For heavy duty cartridge heaters, there is an insertion port or point on the device to be heated. In the case of metal molds and metal blocks, holes are drilled.

According to different power level,cartridge heater can can be high density and low density. High-density fast heat cartridge heater is used to heat plastic injection molds, molds, platens, etc.while low-density cartridge heaters are more suitable for packaging machinery, heat sealing, labeling machines, and hot stamping applications.

Special cartridge heaters can be engineered and designed to meet the most difficult applications and the highest quality standards. From nuclear power plants to open heart surgeries.

So each customer has different requirment for the cartridge heater,custom cartridge heating element is designed to meet each customer's special applications.

The following factors can be designed specially for custom cartridge heater element:

• Custom diameters
• High watt density applications
• Long heater lengths
• Low current leakage constructions
• Special testing and inspection
• Integrated thermostats

We not only sets the industry
standard for cartridge heaters, but continues to make improvements in construction and design for different customers

For example:solutions such as its exclusive resistance wire winding and swaging process. These processes bring the resistance wire closer to the sheath and compacts the MgO insulation to maximize heat transfer. The end result
is longer service life and better efficiency for the cartridge heater.

Cartridge heating element maximize heat exchange performance, providing consistent heating, and also providing specific power and temperature heating for small masses.Our dc cartridge heater is very flexible. Their structure, a stainless steel or incoloy metal tube, is sealed at one end and wires run out from the other, making installation and electrical connections easy.

What details should be confirmed for custom cartridge heaters?

① Select the sheath material

② Confirm voltage and power

③ Confirm the diameter and heating length

④ Select the installation method

⑤ Select the wiring method
