Cartridge Heater bending machine heating tube

I. the introduction of heating tube
The heating tube of the three-D glass hot bending machine is an electric heating pipe installed by punching holes or grooving the mold. Then the head is a fixed stopper, which plays a fixed role. The more common embedded mold single-head electric heating tube is usually straight rod, right angle bent, with fixed stopper.
Using imported production technology, beautiful appearance, long life, high cost performance, the lead is worn out by porcelain beads, with high temperature resistance characteristics.

II. Single head heating pipe application scenario
It is mainly used in hot pressing mold, glass hot bending machine equipment, and can also be used in rice bag sealing machine, 3D printer, edge banding machine heating and other equipment that needs heating.

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.Single -ended cartridge heater tube installation diagram or precautions
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.
