How to use heat shrinkable tube?

First, the use of heat shrinkable tube

1. Prepare materials

First measure and calculate the diameter of the material to be coated, and then select a heat shrinkable tube with a diameter slightly larger than the diameter of the material to be coated.

2. Arrange cables

To prevent the heat shrinkable tube from being punctured during rewinding, remove burrs and sharp corners from the cable, and clean the oil and other impurities from the connected part with a quick-dry cleaning agent.

3, cut the appropriate length

Measure and calculate the length of package needed, then cut the heat shrinkable tube of the same length. When cutting, the cut of the heat shrinkable tube should be neat and smooth, without any cracks or burrs.

4, set into the heat shrinkable tube

Wrap the heat shrink tube into the cable and move it to a proper position. If the cable is bent, smooth the heat shrink tube at the bend Angle to avoid wrinkles.

5, heat the heat shrinkable tube

Use an oven, a heat gun, or a hair dryer to heat the tube in one direction, such as moving from left to right or from right to left. Heating the tube from the middle to both ends is also a good method to avoid air residue in the tube. The heat shrinkable tube tightly wraps the cable after contraction. Therefore, heat the tube evenly to avoid uneven thickness.

Two, the use of heat shrinkable tube matters needing attention

1, the heating distance and time need to grasp, do not exceed the heat shrinkable tube temperature limit, otherwise it will make the heat shrinkable tube “melt” phenomenon.

2, choose the right heating tools, heating the flame and tube surface into a 45° Angle, be sure to move slowly from one end of the hot dormitory administrator to the other end of the uniform speed, to be cooled after the heating tube repair.

3, heat shrinkable tube has different heat shrinkable rate, pay attention to the specification when choosing.

4. The types of heat shrinkable tubes are also different, and the appropriate types need to be selected according to the actual situation.

As can be seen from the above, in fact, the use of heat shrinkable tube method is not difficult, but need to master certain skills, especially the heating step is the key to success or failure. In the use of heating tube, step by step installation material selection, finishing, interception, sleeve and heating these five steps, the basic can learn to use heat shrinkable tube.
