Do you know what are the precautions for shrinking heat shrinkable tubing? Follow the editor of Cheapest high voltage heat shrink tube to have a simple understanding!
1. The heat shrinkable tube and the heating equipment should not be too close. Pay attention to the distance between the fire and the heat shrinkable tube, that is, move evenly by 4~5cm. When heating and shrinking, do not exceed the upper temperature limit of the heat shrinkable tube. For the heat shrinkable tube , If the temperature exceeds the upper limit of temperature resistance, our products will "melt" and return to the initial state.
2. Choose suitable heating tools. When heating and baking, the outer flame of the flame and the surface of the heat shrinkable tube are at a 45 degree angle. Be sure to move back and forth to heat the heat shrinkable tube as a whole, and heat slowly from one end to the other. It must be uniform, avoid bubbles, and ensure the shape of the heat shrinkable tube after shrinking, and trim it after cooling.

3. Heat-shrinkable tubes have different heat-shrinkage magnifications. The specifications of heat-shrinkable tubes generally refer to the product of the maximum allowable inner diameter of the casing after shrinkage and the shrinkage magnification. For example, the shrinkage ratio of the heat-shrinkable tube is 2:1, which means that you can choose a heat-shrinkable tube that is twice the diameter of your own product. For example, if the diameter of the quilt is 20mm, we can choose a heat shrinkable tube with a diameter of 40mm.
4. For linear objects such as wires, select heat shrinkable tubing specifications with the same size as the outer diameter of the product; busbar heat shrinkable tubing should be used for protection of power stations, electrical cabinets and other busbars; waterproof heat shrinkable should be selected for sealing requirements Tube.
To sum up, the editor of Cheapest high voltage heat shrink tube tells: about the precautions when the heat shrink tube shrinks.
