1. Select the appropriate size of heat shrink tube (it is recommended to choose a size 5-10mm larger than the object’s diameter for easy installation).
2. Slide the heat shrink tube over the object to be packaged, ensuring full coverage of the area that needs protection.
3. Use a hair dryer, heat gun, or heat shrink machine to apply hot air evenly at 80°C. The tube will shrink quickly and tightly fit the object’s surface.
4. For uneven surfaces or corners, extend the heating time slightly to ensure no wrinkles or gaps, achieving a smooth and firm fit.
