Where are cartridge heater used?

Due to the small size and high power of the cartridge heater, it is especially suitable for heating

 metal molds. It is usually used with a thermocouple to achieve good heating and temperature control 

effects.

The main application fields of single-head heating tubes are: stamping molds, hot cutting knives, 

packaging machinery, injection molds, extrusion molds, rubber molding molds, melt-blown molds, 

hot press molding machinery, semiconductor processing, pharmaceutical machinery, uniform heating

 platforms, liquid heating, etc. .

For example:

In traditional plastic molds or rubber molds, a single-head heating tube is placed inside the metal mold

 plate to ensure that the plastic and rubber materials in the mold flow channel are always in a molten 

state and maintain a relatively uniform temperature.

In the stamping mold, a single-head heating tube is arranged according to the shape of the mold to 

make the stamping surface reach a high temperature. It is especially suitable for stamping plates or 

thick plates with high stamping strength to increase the efficiency of the stamping process.

Single-head heating tubes are used in packaging machinery and hot-heating knives. The single-head 

heating tube is embedded inside the edge-sealing mold or hot-heating knife mold, so that the entire 

mold reaches a uniform high temperature, and the material can be melted and joined or cut off at the 

moment of contact. Uniform heating single-head heating tubes are particularly suitable.

A single-head heating tube is used in the melt-blown mold. The single-head heating tube is installed 

inside the melt-blown die head to ensure that the inside of the die head, especially the position of the 

wire holes, is at a uniform high temperature, so that the material can be ejected through the wire holes 

after melting. Achieve uniform density. Uniform heating single-head heating tubes are particularly 

suitable.

The single-head heating tube used in the uniform heating platform is to embed multiple single-head 

heating tubes horizontally into a metal plate, and adjust the power of each single-head heating tube 

by calculating the power distribution to achieve a uniform temperature on the surface of the metal 

plate. The uniform heating platform is widely used in target heating, precious metal stripping and

 recycling, mold preheating, etc.

The core heating part of a single-head heating tube (also called a single-head electric heating tube or

 cartridge heater) is a nickel-chromium heat-resistant alloy wire, which is wound around a magnesium 

oxide mandrel with excellent insulation and thermal conductivity. The space between the heating wire 

and the outer shell is filled with magnesium oxide powder as insulating material, and then the air inside 

is compressed and discharged by a machine to make it a whole.

After the main body of the single-head heating pipe is completed, the fixing piece or thread can be 

selected according to the installation needs. The structure of the fixing piece or thread is related to the 

installation method of the heating pipe. Please contact professional technicians for the best solution.
