SL8 FF TR
8-Head CNC Welder for Seamless PVC Windows
The world’s first 8-head welding machine that combines production power with a perfect finish.
Perfect if you want:
- Automating the complete welding of frames with 2 cross members.
- Remove any cleaning or touch-up operations on the corners.
- Working with coated profiles using all types of films, acrylic, wood, or aluminium.
- Automatically compensate for the dimensional tolerances of profiles.
- Reduce production times and operational staff.

Perfect horizontal welding without a bead, even on complex profiles.
The SL8 FF TR is the world’s first CNC welder with 8 heads capable of performing simultaneous welding of the 4 corners at 45° and the 2 cross members at 90° in a single cycle, completely eliminating the weld seam.
The result? PVC frames with an impeccable aesthetic finish, perfectly flat and uniform, even on profiles with non-weldable inserts such as fiberglass, aluminium, or resin.
The automated evolution of the SL4 FF EVO, the SL8 FF TR incorporates the patented V-Perfect technology, allowing for a drastic reduction in cycle times, labour, and footprint. It is ideal for high-productivity companies looking to eliminate any post-welding rework and automate the entire process.
5 reasons to choose SL8 FF TR
- One cycle for the complete frame. Simultaneous welding of the 4 corners and the 2 cross members at 90° in less than 140 seconds with just one operator.
- No rework. The Patented Seamless Welding technology eliminates the need for seams: no cleaners, touch-ups, or rotating tables are required.
- Compatible with all coatings. Painted PVC, acrylic films, wood or aluminium laminates: a perfect finish on every surface.
- Automatic Tolerance Compensation. An intelligent system automatically corrects variations in cutting, geometry, and profile height.
- Maximum automation, minimal labour. The entire process is managed by CNC and proprietary software: you upload the profile, and the machine takes care of the rest.
