the side outlet single head electric heating tube

I.Introduction to the side outlet single head electric heating tube
The side outlet single-head electric heating tube is made by filling the heating wire in the stainless steel metal tube, filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then shrinking the tube, and then processing it into a straight bar shape.

Mainly adopts the conventional straight rod single-head electric heating tube. The side outlet single-head electric heating tube is a kind of electric heating element that punches holes in the mold and embeds the side outlet single-head electric heating tube into the mold hole to transfer heat and heat up the mold. The side outlet single-end electric heating tube can be made into an external wiring or internal lead structure according to the requirements.

Is to weld a hollow casing at the head, open a hole on the side of the hollow casing, and lead the lead of the side outlet single head electric heating tube out of the hole.

Used with temperature control, and ensure that the gap between the mold hole and the side outlet single-head electric heating tube is within a reasonable range, so that the life of the side outlet single-head electric heating tube will be better.

II.the application scenario of single-head electric heating tube with side outlet
The side outlet single-head electric heating tube mainly used in molds that need to be heated, and can also be used in meltblown machines, bag making machines, edge banding machines, packaging machines, 3D printers, mold heating, sealing machines.

The side outlet single-head electric heating tube has simple structure, high thermal efficiency, good mechanical strength, and is suitable for various mold heating. As long as it is metal mold block heating, it can be achieved by punching holes to install the heating tube.

III.Main technical parameters of heating tubes
1. Shell material: 321 imported from Germany, stainless steel 310S material, preferably Ingrid material, high temperature resistance.
2. Heating wire material: 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2, Cr20Ni80, etc
3. Insulating filler: medium temperature insulating magnesium oxide powder, high temperature insulating magnesium oxide powder, etc
4. High temperature lead: mainly porcelain bead lead.
5. Rated voltage: 110V, 220V, 380V, etc
6. Power (surface load): power is determined according to surface load and size, the general surface load is: domestic process: 5W/cm2; Imported process grade A: 5W-12W/cm2; Imported process AA grade: 12W-15W/cm2; Imported process AAA grade: 15W-20W/cm2;
7. Pipe diameter: 12mm-30mm
8. Length: according to customer requirements
9. Cold insulation resistance: the cold insulation resistance should not be less than 50MΩ during factory inspection; After the sealing test, the insulation resistance after long-term storage or use should not be less than 1MΩ
10. Cold leakage current: ≤ 0.5 mA
11. Cold insulation: 1600V. 1/seg

VI.Single -ended electric heating pipe for hot bending machine advantage
1.Non -customized, flexible production, and meet the heating requirements of various equipment.
2.The working temperature can be as high as 760 ° C (imported AAA -level micro -heating pipe)
3.The surface load can be as high as 20-25W/cm2
4.The minimum pipe diameter can be done 3mm
5.K-type or J-type thermocouples can be used to detect temperature
6.It can flexibly add fixing flanges, threads, etc. for fixing

V.Installation diagram or precautions of low-voltage 24V single-head electric heating pipe
For single -ended electric heating pipes, the most important thing is to ensure that the calories of the single -ended electric heating pipe can be passed to the heating medium in time, reducing the temperature of the internal material of the single -ended electric heating pipe. This can effectively increase the single -ended heating tube service life.We should pay attention to the following points during use:

1.Try to reduce the gap between the outer diameter of the single -ended electric heating pipe and the pores of the pores. Usually the gap between the two is less than 0.2mm
2.The installation hole should be able to fit the single -ended electric heating pipe. The deviation tolerance should be controlled within 0.05mm.If you deviate too much, you need to modify the processing hole
3.Before installation of the single -ended electric heating pipe, the impurities left in the holes of the mold should be cleaned. If the residues such as organic oil are left, it will be carbonized after heating, which will affect the ability of thermal conduction.

VI.Description of the wiring method of Single-head heating tube
A pipe connected to the power supply: directly according to the voltage size to wire, usually 220V, a live wire, a zero wire; 380V, if there are only 2 terminal posts, then it is enough to connect 2 live wires.

Multiple pipes connected to the power supply: can be taken according to the actual situation: parallel, series, delta connection or Y-type connection, etc. If you don’t understand the details, you can consult our sales customer service.
