SL4FF WD
CNC 4-Head Welder for Wood Effect Profiles and Seamless Welding
The world’s first welder that combines a wood-effect aesthetic with seamless performance.
Perfect if:
- Remove the welding bead from the corners of the frames.
- Reproduce the wood effect accurately with 45°/90° joints.
- Working with profiles that have fiberglass, aluminum, or resin inserts.
- Reduce production time and labour costs
- Achieve flawless finishes without the need for cleaning or touch-ups.
- Integrate the welder into an Industry 4.0 line.

The world’s first welder that combines a wood-effect aesthetic with seamless performance.
SL4FF WD is the first CNC welder with 4 heads capable of completely eliminating the welding seam from corners, producing PVC frames with superior aesthetic quality, even on complex profiles like wood-effect designs. This revolutionary technology allows for welding on two sides with different geometries (45° + 90°) to faithfully replicate the appearance of wooden windows, without compromising on strength and precision.
Thanks to the patented V-Perfect technology, the machine processes coated, painted, and laminated profiles made of wood or aluminium without the need for post-processing touch-ups. All operations – milling, positioning, melting, compression, and cooling – are fully automated and ensure consistent results even on profiles with non-weldable internal materials.
5 Reasons to Choose SL4FF WD
- Unique wood effect welding. Achieve the ‘timber look’ with the double 45° and 90° joint geometry on opposite faces.
- Seamless welds with no rework. Eliminate the bead with V-Perfect technology: smooth surfaces, no manual cleaning required.
- Maximum compatibility with special materials. Works with profiles that have non-weldable cores such as fibre, aluminium, and resin.
- Active control of the final result. Active welding system with software adjustments for tailored results.
- One operator, maximum efficiency. No need for a cleaner or a rotating table: optimising time and resources.
