Spot Welding Machine nekonultrasonics.com

Ultrasonic spot welding machines​ redefine efficiency in joining flat or complex thermoplastic components without pre-molded weld preparations. Designed for seamless integration into diverse production environments, our ultrasonic welding machines deliver rapid, clean, and high-strength spot welds for applications ranging from zipper assembly to medical mask ear straps.

​How It Works​
Nekon's ultrasonic spot welding technology employs ​high-frequency vibrations​ to create localized bonds:

• ​Sonotrode Penetration: The horn tip penetrates the upper layer, generating friction at the contact surface.

• ​​Material Plasticization: Frictional heat melts the thermoplastic precisely at the weld point.

• ​​Bond Formation: Molten material solidifies into a durable, ring-shaped joint with minimal surface marks.

This process is ideal for materials up to ​8 mm thick​ and supports both stationary and handheld operations.
