Ultrasonic welding means joining without adhesives, screws or heat from an outside source. During this process, plastics are strategically melted by means of ultrasonic vibrations so that a cohesive or form-fit joint is produced. As economic production method with short cycle times, ultrasonic welding ensures a large degree of process control and repeatable quality results.
Ultrasonic welding uses high-frequency ultrasonic acoustic vibrations which are applied to materials that are being held together under pressure to create a solid-state weld. This method is most commonly used to join thermoplastics and in joining materials that arenâ€™t similar and does not require any bolts, nails, soldering material or adhesives that are needed to join the materials together. Although ultrasonic welding uses vibration to create a weld, ultrasonic welding is a different method from “vibration welding” (also known as friction [...]
