Ultrasonic welding has significant advantages in the packaging industry

Ultrasonic welding is widely used in our daily lives, especially in the packaging industry. To understand the application of ultrasonic welding in the packaging industry, it is necessary to first understand the working principle of ultrasonic welding machines:
The ultrasonic plastic welding machine transmits ultrasonic energy to the welding area through the upper weldment. Due to the high sound resistance at the interface between the two welding areas, local high temperatures will be generated. Due to the poor thermal conductivity of plastic, it cannot be released in a timely manner and accumulates in the welding area, causing the contact surface of the two plastics to quickly melt. After applying a certain amount of pressure, it merges into one. After the ultrasonic stops working, the pressure is allowed to continue for a certain amount of holding time to solidify and form a solid molecular chain, achieving the purpose of welding. The welding strength can be close to the strength of the raw material itself.
Therefore, the application of ultrasonic welding is very extensive. Today, we will introduce the significant advantages of ultrasonic welding in the packaging industry:
1. Greatly reducing processing time, the bonding between plastics can be completed within a few milliseconds;
2. Ultrasonic energy is only consumed in the precise area that needs to be welded, which is efficient and energy-saving;
3. Sealed welding can be carried out through dirt (such as liquid, grease, powder, etc.) without affecting the welding effect;
4. Ultrasonic equipment and its components are easy to use in automated environments and compatible with boring conveying systems;
5. The application of ultrasound for processing ensures a clean, stable and reliable process. And the energy consumption is low;
6. There is no need to use safe and easily polluting auxiliary products, such as adhesives, fasteners, or adhesives, and the processed packaging is environmentally friendly and renewable;
7. By utilizing welding units, non-standard equipment for welding different products can be designed according to customer requirements.
Not only in the packaging industry, but also in the electronics industry, ultrasonic welding is widely used, mainly in the following two categories:
Electronic products: computer keyboard, battery, computer casing, computer decorative strip, data cable, LCD display screen, mouse, MP3.
Communication equipment: mobile phone board, phone microphone, phone antenna, phone case, charger, power supply case.
