Electric cartridge heater china
The electric heater cartridge is a device consisting of MgO powder or MgO tube, ceramic cap, resistance wire (NiCr2080), high temperature lead, seamless stainless steel sheath (304,321,316,800,840).
Usually tubular, the metal block is inserted through a series of holes in the heating application.
Box heaters come in two basic forms: high density and low density.
High density box heater is used for heating plastic injection mold, mould, pressing plate, ecc., while low density box heater is more suitable for packaging machinery, heat sealing, labeling machine and hot stamping
Cartridge heaters can be considered “element heaters” and generate heat in many different applications.
These process heaters are used primarily in molds, fit in cavities, and help heat solids to high temperatures.
The box heater is versatile and can carry thermocouples to help control the heater temperature more accurately.
The various diameters allow it to be used in any cavity and can be customized with any cold section.
The leads extend from the end to the control panel.
Box heater is a water heater element, widely used.
These applications include bag seal applications, hydraulic oil applications, oil applications, gear boxes, water heating applications, and laboratory and food equipment.
The enclosure can reach extreme temperatures because the box heater can be designed with a higher watt density.
High power density box heaters may also have different types of lead connections.
In more machining, stainless steel braided leads are used to resist mechanical stress.
BX wiring can be used for additional protection, although it reduces lead flexibility.
All models of terminal pins are available.
The heater is composed of a high quality ni-cr resistance wire wrapped in a high quality MgO core which is located in the center of a stainless steel housing.
