THE MOST ADVANCED EDGE FOLDING TECHNOLOGY
Flawless edges - guaranteed
We offer machine and tooling technology optimally matched to your project and material requirements. Volumes and cycle times determine whether single-station or in-line solutions will be the best fit. Our machines' high standards can be expanded with a variety of options. The process for edge folding with adhesives depends on the type of adhesive.
The processes differ depending on whether the adhesive needs to be activated or not. Parts with intricate geometries often contain complicated edge fold areas. Our edge fold slider designs, which we have perfected over the years, play a key role under these circumstances. FRIMO edge fold sliders close seamlessly and move independently, both vertically and horizontally.
FRIMO thermo-edge folding is a completely adhesive-free process. Heated sliders are used to melt pre-existing weld ribs on the back side of the substrate, creating a strong bond with the decor.
This adhesive-free process is used for back injected or back pressed parts with edges that are covered in a decor by edge folding. This process is great for textile decors and special material combinations, making it ideal for applications such as edge folding pillar trims.
ADHESIVE-BASED EDGE FOLDING
Advanced standard design with a variety of options
FRIMO edge folding systems with adhesive activation allow adhesives to be activated through heat, and come in the following technical configurations:
- Hot air channel system
for adhesive activation in the edge folding area and for decorative material heating - Heated sliders
for heating through the decorative material into the glue area - Infrared heating
via infrared flash emitters for heating the edge folding area
FRIMO edge folding systems without adhesive activation use either contact adhesives or hot-melt adhesives that are applied shortly before edge folding and are already activated. Temperature-controlled sliders are used to apply the adhesive.
FRIMO ADHESIVE-FREE EDGE FOLDING
Tooling and equipment from a single source
FRIMO edge fold systems that do not use adhesives are very efficient and allow short cycle times of under 35 seconds. Empty nest part loading and integration of punching, welding, clip assembly, or inspection are possible options.
- Hot air edge folding
Melting substrate material's surface with hot air, edge folding via temperature-controlled sliders; particularly well suited for processing thermoplastics such as PP, PE and PP natural fibers - Heated sliders
Melting the decorative material and substrate in the edge folding area (for thermoplastics and duroplastics)
