The main characteristic of heat shrinkable tubes is that they can be heated and shrunk to make the inner diameter smaller. The correctness of the shrinkage method determines the protective effect and life span of the heat shrinkable tubes. However, this kind of heat shrinkable tube has unique characteristics of shrinking when exposed to heat. Many users do not know the correct way to bake (heat) heat shrinkable tubes. Today, I will teach you the correct way to bake heat shrinkable tubes, so that everyone can get twice the result with half the effort in the shrinkage process of heat shrinkable tubes. , improve production efficiency and yield rate.

1. When choosing tools for shrinking heat shrink tubes, the editor first recommends the heat gun. It is cheap and easy to use. It is also the most commonly used method at present.

2. Heat shrinkable tube heating method: first start heating from one end, and make the hot air gun spirally rotate around the heat shrinkable tube to heat evenly (or rotate the heat shrinkable tube to heat evenly), which can make the heat shrinkable tube heated more evenly and shrink more smoothly ,fit.

3. Heating the shrinkage part of the port should take a longer time. After the port of the heat shrinkable tube has completely shrunk and completely fit the product, start to move longitudinally and heat the other end in turn until it is completely shrunk.

4. After complete shrinkage, pass the heat gun over the surface of the heat shrink tube twice more to make the heat shrink tube shrink more smoothly.

   Precautions for shrinking heat shrink tubing:

1. Remember not to shrink across sections, otherwise bubbles will easily occur in the middle. Heat it from the left, then the right, and finally the middle. Remember not to use this method, as it can easily produce wrinkles and bubbles. The picture below shows the wrong heating method. In order to make it more intuitive for everyone, a glued heat shrink tube is used, and the bulge is more obvious.

2. Do not heat one part for too long during the heating process. It is easy to burn out the heat shrink tube and affect the overall quality of the product.
