Ultrasonic welding Plastics Packaging Nonwovens

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.

Overview of Ultrasonic Welding

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 aren’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 [...]
