There are many ways to use heat shrink tubing. On the Internet, you can see how to burn it with a lighter, scald it with boiling water, use a hair dryer, etc. If a suitable shrinking method is not selected, there will be phenomena such as bubbling and burning, unevenness, and wrinkles due to insufficient shrinkage. If a suitable shrinking method is not selected, uneven wall thickness will also occur after shrinkage, that is, one side will be thicker. Thin on one side. These problems are generally caused by not paying attention to the method during shrinkage and uneven heating. As a heat shrink tube manufacturer, I would like to briefly introduce to you a shrinking method of heat shrink tube that is economical, affordable and very effective.

    Why do the above-mentioned adverse phenomena occur? We must find out the reasons and then we can solve them well. The main reason for bubbling and burning is that the temperature is too high, which usually occurs when a lighter is used to heat and shrink. The main reason is that the temperature is difficult to control, the heating area is relatively limited, and some places cannot be baked at all. The reason for the unevenness and wrinkles is mostly that the shrinkage is not in place. The heat shrink tube has not completely shrunk in place, that is, the temperature is too low. It is easier to understand that the main reason for failure is that the temperature is too high or too low. Using a heating tool with a suitable temperature can solve the problem. We generally recommend using an industrial hot air gun, which is cheap and has good shrinkage effect. The temperature can be adjusted by yourself from 70 to 400°C. Choose the appropriate temperature according to the model of the heat shrink tube. Can. The specific shrinking steps are as follows:

1. The complete shrinkage temperature of the heat shrink tube is generally around 110°C. Adjust the temperature of the hot air gun to 110°C. After turning on the hot air gun, you need to preheat it until the temperature completely reaches 110°C. Remember not to point the air gun as soon as you open it. Blow out the heat shrink tubing.

2. The process of heating and shrinking must be done from left to right, or from right to left, until the heat shrink tube has completely shrunk and is close to the wrapped object, and then move the heat gun in sequence. It must not be heated and shrunk from both ends to the middle. This will easily cause a bulge in the middle, that is, there is air in the middle that has not been discharged.

3. When the heat shrink tube shrinks, the heating object must be rotated so that all angles of the heat shrink tube can be heated evenly, so that there will be no uneven wall thickness, that is, one side is thicker and the other is thin.

    Follow the above three steps and with simple exercises, you can shrink a very beautiful product. Heat shrink tubing is a commonly used insulating and protective auxiliary material. The method of use is also very simple. Shrinking using a hot air gun is a widely used shrinking method at present. The advantages are also very obvious. The temperature is adjustable and the cost is low.
