1. High welding quality:
High strength: ultrasonic welding can make fabric materials fuse with each other at the molecular level to form a strong connection, the welding strength is close to the strength of the raw material body, the connection is firm and reliable, not easy to break, and can withstand large tensile and shear forces.
Good sealing performance: the fabric after welding has excellent sealing performance, which can effectively prevent the penetration of liquids, gases, etc., which is of great significance for some industrial fabric products with high sealing requirements, such as waterproof fabrics and air filtration materials.
High dimensional accuracy: the heat affected area of the fabric is small during the welding process, which will not cause obvious deformation or contraction of the fabric, and can maintain the original size and shape accuracy of the fabric to ensure the consistency of the product.
2. High welding efficiency:
Fast: Ultrasonic welding is a high-speed welding method, the welding time is short, usually in a few seconds or even shorter time to complete the welding, can greatly improve production efficiency, to meet the needs of large-scale industrial production.
Easy automation: Ultrasonic welding equipment is easy to integrate with automated production lines, which can achieve continuous and efficient production, reduce manual operation, reduce labor intensity and production costs.
3. Environmental protection and no pollution:
No need to add auxiliary materials: the welding process does not need to use glue, adhesives and other auxiliary materials, to avoid the environmental pollution caused by the use of these materials and the pollution of the fabric, but also reduce the consumption and waste of materials.
4. Energy saving: The energy consumption of ultrasonic welding equipment is relatively low, and only a small amount of electricity is consumed at the moment of welding, which can save a lot of energy compared with traditional thermal welding methods.
The development trend of ultrasonic welding in the field of industrial fabrics:
1. Intelligent equipment:
Improve the level of automatic control: the future ultrasonic welding equipment will have a higher level of automatic control, can realize the automatic adjustment and optimization of welding parameters, according to different fabric materials and welding requirements, automatically select the right welding parameters, improve welding quality and production efficiency. For example, the temperature, pressure, amplitude and other parameters in the welding process are monitored by the sensor in real time, and the working state of the equipment is automatically adjusted according to the feedback information.
2. Welding process innovation:
Multi-material composite welding: With the continuous development of industrial fabric materials, more and more composite materials will be applied in the industrial field. In the future, ultrasonic welding technology will continue to innovate, and can realize composite welding of a variety of different materials, such as fabric and metal, fabric and plastic, welding between different fiber materials, etc., to expand its application range.
Micro-nano welding technology development: In some areas with high requirements for welding accuracy, such as microelectronics, nanotechnology, etc., micro-nano welding technology will become the focus of development. Ultrasonic welding technology will continuously improve its welding accuracy and resolution to meet the needs of micro-nano scale welding.
Degradable materials welding: With the continuous improvement of environmental awareness, the application of degradable materials in the field of industrial fabrics will be more and more extensive. In the future, ultrasonic welding technology will develop corresponding welding processes and equipment for the characteristics of degradable materials, achieve efficient welding of degradable materials, and promote the green development of industrial fabrics.
