Ultrasonic welding is a proven and state-of-the-art technology for joining thermoplastic plastics. By using high-frequency mechanical vibrations, frictional heat is generated, which selectively melts the joining surfaces and bonds them reliably – without the use of adhesives, screws, or other fastening elements.

Advantages of ultrasonic welding

Fast cycle times

Ultrasonic welding enables extremely short welding times in the millisecond range. This significantly accelerates production processes and reduces costs.

Material and resource conservation

Since no additional joining materials such as adhesives or screws are required, material consumption and environmental impact are reduced.

High process reliability and repeatability

Thanks to precise control and modern sensor technology, consistently high quality and reliable weld joints are ensured.

Clean and visually appealing weld seams

The connection is made cleanly, without contamination from adhesives or mechanical fasteners – ideal for visible components and sensitive applications.

Energy-efficient and environmentally friendly

The targeted energy input minimizes power consumption and reduces emissions, making ultrasonic welding a sustainable alternative in plastic processing.

Conclusion

Ultrasonic welding of plastics offers an efficient, clean, and cost-saving joining technology for numerous industrial applications. With its high process reliability and environmental friendliness, it is the ideal solution for modern production requirements.

Applications - Ultrasonic welding is successfully used in various industries, including:

  • Medical Technology – sterile and precise connections
  • Electronics Industry – secure bonding of plastic housings
  • Packaging Technology – tight and fast sealing
  • Automotive Industry – for interior and exterior components

Sustainable solutions

Nolato in Switzerland relies on electrically driven welding presses with servo motors. Compared to conventional welding machines with pneumatic drives, the advantage lies in accuracy and, above all, sustainability. According to the manufacturer's measurements, energy savings of up to 78% are possible, depending on the application and the setting parameters.

Collaboration

The key to the successful implementation of an ultrasonic welding process is the upstream discussions and the appropriate design of the weld seam geometry. Appropriate preliminary tests or pre-holding masses can help to bring the process quickly and optimally to series maturity. With decades of experience, Nolato can support you and optimally develop your plastic parts for the successful production of assemblies using ultrasonic welding.
