Advantages of FIP:

  • Geometrical freedom: No rotational symmetry required
  • Higher Strength: With less material, higher strength can be achieved
  • Reduced time and costs: Very fast process and less parts to manipulate which reduces costs

Key Features:

  • Advanced EPP Foam Fastening: Utilizes MM-Welding® process with ultrasonic vibration for fast and strong fixation in EPP foam, making it an ideal solution for HVAC fasteners and more.
  • Optimized for Various Densities: A standard solution for a wide range of particle foam densities, offering versatility in application.
  • Rapid and Effective Installation: Features a very fast processing time of less than 3 seconds, coupled with high pull-out strength and torque resistance, ensuring optimal integration with materials.
  • Seamless Integration: Allows for full integration into the substrate, with the capability of placement even close to the edges of EPP panels, providing greater design flexibility.
  • Compact Design: Designed with a low fastener height to minimize space constraints, making it suitable for use in tight spaces like HVAC systems.
