Reliable fastening of different materials using an ultrasonic process
Above all in lightweight structural engineering, innovative fastening solutions which offer the highest degree of reliability and efficiency are in great demand. Through the introduction of ultrasonic energy to fixing and fastening solutions, joining of element is accomplished safely and in many cases without much preparation. Ideally, the connecting element should become part of the carrier material.
The MM-W™ technology originated from the WoodWelding® technology, which has been in use for years not only in woodworking but also in surgery.
Now is the time to use the digitalization boost and optimize processes
MultiMaterial-Welding is revolutionizing joining technology with its technology platform to give you exactly the digital advantage. In our video, we would like to demonstrate how the complete automation of plant engineering is simplified and how the entire production chain can be digitized for faster and more economical production processes.

Johann Borgers GmbH uses the technology platform MultiMaterial-Welding
Johann Borgers GmbH develops custom damping, insulation and equipment solutions for a number of different passenger car and truck models. Different joining techniques are used depending on the installation location on the outer body as well as in the engine, passenger and trunk compartments. With the new MultiMaterial -Welding (MM-W) technology from KVT-Fastening, Borgers was able to implement a fastening variant for a trunk floor with a paper honeycomb core for a luxury SUV, which could not be realized from a technical point of view using conventional methods. > read moreMM-Welding® - Fastening Technology that pays off
Manufacturing companies do not only expect proven technologies, but also efficiency and low cost when selecting fastening solutions. But how do you find the optimal process among so many available options? Florian Beer, Managing Director of KVT-Fastening GmbH gives interesting insights into the topic of MM-Welding® in an interview.

MM-Welding® technology portfolio
LiteWWeight® Pin
This is a family of fasteners with easy one-sided access assembly process designed to realize fast and strong fixation on sandwich structures with internal honeycomb or similar patterns.
Application
- Fastening on foamed honeycomb structures and/or porous building components
- Typical application: Load floor, parcel shelf, roof panel
Features
- Full integration in substrate possible
- High strength: Pull-out forces of higher than 1000N can be achieved through deep integration into HCB material
- Very fast processing time of ~1 second
- No pre-drilling necessary in most cases
- Possible to pierce through thick decor materials
- Placement directly at the edge of the material possible
- The different fastener geometries enable different types of applications

LiteWWeight® Double Pin
This fastener is designed to realize fast and strong fixation that can be designed for plastic direct screws, with a metric internal thread or even with a through-hole. The fastener consists of a sleeve, as slide and optionally a metallic insert, which can be selected according to the application.
Application
- For connection into lightweight sandwich panels made of aramid, polypropylene, and more
- Nomex honeycomb panels for aerospace applications: In aerospace industry, certification is crucial for the acceptance of each part. The LiteWWeight® Double Pin includes standard materials for aerospace, and is an ideal replacement for gluing where material content complicates the certification process.
- Polypropylen honeycomb panels: Internal cavities of polypropylen honeycomb panels make it difficult to install standard connectors such as screws as they don’t have a structure to hold on to.
- The LiteWWeight Double Pin® is designed to attach strongly to this type of material, and if necessary allows the inclusion of a metallic thread.
Features
- High versatility: can contain a clearance hole, a threaded hole or a metallic insert (M3 to M8)
- Quick installation process time of < 0.7 seconds
- High strength due to creating form lock to top-layer and conventional weld-connection to bottom-layer
- Full integration in substrate possible
- Pull-out forces of higher around ~ 2000 N can be achieved through deep integration into HCB material
LiteWWeight® zEPP
LiteWWeight® zEPP is a fast and efficient fastening technology for all expaned polyproylene (EPP) materials based on the innovative MM-Welding® process.
Application
- Solution for fixation into expanded polypropylene (EPP) foam
- Dowel solution to create a durable threaded fixation point with or without metal insert
Features
- Very fast cycle times (~1 second)
- High pull-out force due to optimal anchoring with the EPP material
- Very high torque transmission possible due to MM-Welding® specific "Anti-Turning" geometry
- Full integration into the substrate
- Placement directly at the edge of the material possible
- Low overall height of the fastener increases design freedom
- Applicable for all density ranges
- No pre-drilling necessary

- Suitable for decorative and structural parts within automotive, aviation or rail industry
Features
- Very fast processing time of only 1 second
- Suitable also for low wall-thicknesses
- No pre-hole or through-hole required
- Strong form locking due to innovative crater shaped design
InWWerse® Disc
Fastening solution for joining dissimilar thermoplastic as well as very thin materials (< 2.5 mm) without creating marks.

Features
- Very fast cycle times
- High strength due to intensive integration in the fibre matrix
- Simple and more complex 3-D geometries (due to direction of motion of the fastening element only being in the z-direction)
- Ideal integration into textile structures possible
