Key Features:

  • Adaptable Design: The Double Pin can be equipped with a clearance hole, a threaded hole, or a metallic insert (ranging from M3 to M8), providing high versatility for various fastening needs in sandwich panel and honeycomb panel applications.
  • Rapid Installation: Boasting a quick installation process time of less than 0.7 seconds, it streamlines assembly processes, particularly in fast-paced environments such as tier 1 aerospace suppliers and aircraft interior manufacturing.
  • Exceptional Strength and Integration: Designed to create a form lock to the top layer and a conventional weld-connection to the bottom layer, the Double Pin achieves full integration in the substrate.
  • Metallic Insert Option: Offers the flexibility to include a metallic insert for strong, dismountable connections, ideal for applications where adjustability and serviceability are required, like HVAC fasteners or aerospace fastener companies.


Applications in Aerospace and Other Industries:

  • Aerospace Industry: The Double Pin is crafted with standard materials for aerospace, making it an ideal replacement for gluing in aircraft fastening, where material content can complicate the certification process.
  • Thermoplastic Sandwich Panels: Specifically designed to attach strongly to honeycomb panels, which often present challenges for standard connectors like screws due to their internal cavities.

Explore the potential of the LiteWWeight® Double Pin – a fastener that redefines the standards of strength and versatility for lightweight materials in aerospace and beyond, brought to you by MultiMaterial-Welding AG.

Simple and Efficient

The installation involves positioning the substrate material with a prepared hole, inserting the slide, and then the sleeve with or without an insert. The MM-Welding process using ultrasonic energy liquefies the polymer to create a strong connection to both layers.
