Ultrasonic Welding

Ultrasonic Welding for Films and Non-Wovens

Midwest Engineered Systems designs and integrates ultrasonic plastics welding systems engineered for consistent, high-quality welds across a range of thermoplastic materials. Using high-frequency ultrasonic vibrations, our equipment joins, seals, or cuts materials without adhesives, solvents, or excessive heat—making it ideal for nonwoven, film, and flexible plastic web applications. MWES solutions deliver repeatable performance, clean weld seams, and faster cycle times for both continuous and intermittent production processes.

High-Precision Welding for Web and Part Applications

Ultrasonic welding offers a clean, efficient alternative to traditional bonding methods by creating molecular-level joins through vibration and pressure. MWES engineers systems for a wide range of applications, from web-based sealing and fabric bonding to part joining and assembly. Each system is tuned for your specific material thickness, geometry, and production speed—ensuring consistent results and minimal material stress.

Benefits of Ultrasonic Welding Technology

  • Clean and Precise Welds: No adhesives, consumables, or contamination
  • Fast Cycle Times: Instant bond formation for high-throughput operations
  • Energy Efficient: Uses focused vibration energy only where needed
  • Strong, Repeatable Bonds: Consistent weld quality across production runs
  • Low Maintenance: Minimal tooling wear and fast setup changes
