Advantages and disadvantages of ultrasonic welding

Ultrasonic welding is the most widely used plastic bonding technology in the industry. It is fast, economical and easy to integrate with automation. It is ideal for mass production operations, with production beats up to 60 pieces per minute. Good weld stability and high strength. The welding time is shorter than other welders and there is no need for complex ventilation systems to remove smoke and cooling systems to remove excess heat. High energy utilization. Compared with other plastic welding processes, the production efficiency is higher and the cost is lower. The mold design is relatively simple, can realize the rapid mold change, increase the utilization rate and versatility of equipment. Because there is no introduction of other auxiliary welding materials in the weld, so the weld is clean without impurities and does not affect the biocompatibility of the equipment. It is also widely used in the medical and health care industry with higher requirements. Limitations of ultrasonic welding. When the product size exceeds 250mmX300mm, the welding head design is difficult and cannot be completed in one welding. It is often necessary to use a plurality of welding joint synchronous welding, or a single welding joint for several times. The result of ultrasonic welding is closely related to weld structure design, dimension error and deformation of injection parts. Ultrasonic vibration can easily cause damage to sensitive electronic components, although higher frequencies and reduced amplitude can reduce such damage.

Application field

Ultrasonic welding is suitable for almost all major industries. Automobile: headlights, instrument panel, buttons and switches, fuel filters, liquid containers, seat belt locks, electronic key locks, lamp assemblies, air ducts. Electronics and electrical appliances: switches, sensors, actuators, etc. Medicine: filters, catheters, medical clothing, masks. Packaging: blister bags, bags, storage containers, nozzle.
