MM-Welding ultrasonic welding

The Evolution of Ultrasound application in Industrial Applications

Our innovative technology uses ultrasonic waves and friction to create strong, durable Form-fit connection into porous materials and/or geometrical undercuts. It allows the assembly combination of challenging materials such as metal to plastic and various thermoplastic composites.

LiteWWeight™ technology, a signature product of MM-Welding, exemplifies this innovation. It utilizes ultrasonic energy to bond thermoplastic fasteners into porous and lightweight materials efficiently, marking a significant leap in existing assembly capabilities. By eliminating the need for most pre-processing work and completing processes in under a second, MM-Welding offers a robust, reliable, and time-efficient solution.

Advancing Beyond Traditional Methods: MM-Welding's Innovative Approach

With the InWWerse™ technology,  MM-Welding's approach to joining transcends traditional methods, offering numerous advancements and benefits over traditional ultrasonic welding or adhesive bonding.

The "porosity" needed for the MM-Welding process is brought by the fastener itself and allows a rapid and efficient connection onto thermoplastic thin trim part. Removing the need for surface compatibility or manual preparation, the full assembly process becomes fast and precise.
