Heat shrinkable casing operation method, double wall heat shrinkable tube overflow too much how to do, heat shrinkable casing has what role must be clear

Operation method of heat shrinkable casing

Heat shrinkable bushing is a kind of protective bushing commonly used in all trades and professions. It can achieve the effect of short heat shrinkage. The relative electrical tape is relatively undetermined, the operation life is longer, the performance is durable and stable, and of course, it is effective against aging. It's easy to understand the suitable material. Before it is suitable, it's more convenient. Before wrapping the product, it can also cause all kinds of problems. This time, we talked about how the heat shrinkable sleeve is suitable for the related common problems.

What are the advantages and characteristics of heat shrinkable tube?

Heat shrinkable sleeve is like a kind of processing polyolefin raw material heat shrinkable short sleeve. If a small amount of heat is made, it will start to shrink when heated to 125 ℃. When I realize the flexibility, the heat shrinkable sleeve is like a kind of polyolefin heat shrinkable sleeve, which is also beneficial to EVA material.

What are the functions of heat shrinkable sleeve?

Heat shrinkable tube is best used in battery, electronic components, cable and electrical appliances, wiring harness, pipeline corrosion and other areas.

In accordance with the requirements of professional heating tools, the heat shrinkable sleeve can be tightly wrapped, which will have insulation, protection and other functions.

How to fully fit heat shrinkable casing?

Finally, the heat shrinkable sleeve can be placed on the coating, and all components can be installed and selected successfully. After the screws have been tightened, the heat shrinkable sleeve can be arranged and laid well, and it can be held in a small number of positions. The hot air heater can heat shrinkable the sleeve on the coating.

Heat shrinkable casing operation scale?

Heat shrinkable sleeve has been widely used in the insulation maintenance of different batteries, wiring harness, inductive components and solder joints, as well as the anti rust and anti-corrosion of telescopic rod, metal tube and pipeline.

What is the heating method of heat shrinkable sleeve?

The common heating elements are suitable for electric hair dryer, heat shrinkable casing machine, high temperature electric furnace, etc.

How to deal with excessive glue overflow of double wall heat shrinkable pipe

It is regarded as a double wall heat shrinkable tube. It has to choose the function of sealing. In addition, during the heating process, the hot melt glue in the inner layer melts and flows to fill the corresponding gaps, so as to achieve sealing. Therefore, its own flow can also overflow along the edge of the heat shrinkable tube, which makes it difficult for manufacturers to process heat shrinkable tubes, Will also operate the degree of overflow is seen as a processing can all-round reference, so we have not talked about this is not good.

What we talked about is that it's natural for the heat shrinkable casing to overflow, but its overflow can also bring corresponding bad effects. The figure below is a relatively conventional situation. Generally speaking, there is no impact on the performance and appearance. The rest of the situation is not very certain.

As shown in the following figure, when the double wall heat shrinkable tube has to be used on some ring terminals, whether it's a small square ring terminal, or a large square cable battery line, the front terminal is regarded as the connector for further operation, but the round hole is the center, and a circle of metal around it is generally known for welding and so on, When the heat shrinkable tube is heated, the hot melt adhesive overflows too much, thus covering part of the metal position. In this case, the following assembly options may be affected, so it seems that it is impossible. How to realize this? On the one hand, compared with the production of wire harness, it is possible to consider the appropriate example of the connection; On the other hand, the selection of heat shrinkable sleeve is related to the processing, which can select the heat shrinkable tube with no more than a lot of glue. In addition, the position will be controlled during the processing, so it is not easy to move forward.

Compared with the ultrasonic splicing line, there may be too much glue overflow, which is not good, so it is even more troublesome in the processing process. When there is too much glue overflow, when the heat shrinkable tube comes out of the heating equipment, the two often stick together, and stick to the equipment not long ago, which leads to a bad waste of working hours, so that it is like scrapping. To be determined, on the one hand, it is like poor selection. If you choose a larger diameter heat shrinkable tube to seal a smaller wire harness, the glue flowing out naturally may not be good. Therefore, you need to choose a more matching size. On the one hand, excessive heating may or may not cause too much damage. If the heating is too long, the glue will flow out one after another, Therefore, the desired control parameters should be selected.
