1.Introduction to single -ended electric heating pipes

Single -ended electric heating pipes, also known as straight single -header heating pipes. The use of single -ended electric heating pipes is to punch holes on the mold, embed the single -ended electric heating pipe in the moldhole, and then connect to the power heating element that heats up the power and heat it to the mold. Single -ended electric heating pipes can be made into external wiring or internal leading structures according to demand.

2.Single -ended electric heating pipe application scenario

Single -ended electric heating pipes are mainly used in various molds, which can be used in melter -spray machines, bag making machines, border sealing machines, packaging machines, 3D printers, mold heating, sealing machines.As long as the metal mold block is heated, it can be achieved by installing the micro -heating pipe.

3.Main technical parameters of single -ended electric heating pipes

①Shell material: stainless steel 304, stainless steel 321, stainless steel 310s, Ingle 800, Ingle 840, etc.

②Electric heating wire material: 0CR25AL5, 0CR21AL6NB, 0CR27AL7MO2, CR20NI80, etc.

③Insulation filling: Magnoma oxide powder, high temperature insulation magnesium oxide powder, etc.

④High -temperature lead: Silicone high -temperature lead, Yunmu high temperature lead, silicone glass fiber tin -plated copper wire, Yunmu glass fiber pure nickel thread, etc.

⑤Rated voltage: 12V, 24V, 36V, 48V, 110V, 220V, 380V, etc.

⑥Power (surface load): The power is determined according to the surface load and size. The general surface load is: domestic process: 5W/cm2; import process A level: 5W-12W/cm2; import process AA grade: 12W-15W/cm2; import Craft AAA level: 15W-20W/CM2;

⑦Pipe diameter: 3mm-25mm

⑧Length: according to customer requirements

⑨Cold -state insulation resistance: The cold -state insulation resistance should not be less than 50mΩ when the factory test.After the sealing test, the insulation resistance after a long time of storage or use should not be less than 1MΩ

⑩Cold leak current: ≤ 0.5 mA

⑪Cold -state insulation:1600v. 1/seg

4.Single -ended electric heating pipe product advantage

①Non -customized, flexible production, and meet the heating requirements of various equipment.

②The working temperature can be as high as 760 ° C (imported AAA -level micro -heating pipe)

③The surface load can be as high as 20-25W/cm2

④The minimum pipe diameter can be done 3mm

⑤K-type or J-type thermocouples can be used to detect temperature

⑥It can flexibly add fixing flanges, threads, etc. for fixing

5.Single -ended electric heating pipe 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 -header heating Life life of the tube.We should pay attention to the following points during use:

⑴Try 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

⑵The 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

⑶Before 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.

6.Single -ended electric heating pipe description

Single -rooted pipe connecting power: Cable directly according to the voltage size, usually 220V, a fire line, a zero wire; 380V, if there are only 2 wiring columns, then you can connect 2 fire lines.

Multi -rooted tube connection power supply: You can adopt: parallel, series, triangle connection, or Y -type connection method. If you do n’t understand, you can consult our sales customer service.
