SL4-FF EVO Wood – 4 Head CNC Welding Machine


The first and only 4-head CNC welding machine in the world that completely eliminates the welding bead from the corner and allows you to weld profiles with a joint that simulates the assembly angle of a wooden window frame on one of the faces. Unique machine of its kind, it performs both seamless welds with traditional angle joined at 45o and “Timber look” effect closures for which it welds one side at 45o and the opposite face at 90o while maintaining uniform quality and superior aesthetics.

The SL4-FF EVO Wood guarantees absolutely flat and homogenous surfaces even with profiles that, instead of reinforcing metal, have inside them non-weldable products such as fibreglass, aluminium or resin.

5 Reasons to choose SL4-FF EVO Wood

  • Flexible – The machine can weld seamless standard and Timber Effect windows.
  • Versatile – White and foiled seamless welding. Aluminium clad welding.
  • Efficient – One operator required. The seamless welding eliminates the need for corner cleaning.
  • Active Welding System – The operator is informed of all weld tolerances prior to welding.
  • Concise Welding – All profile tolerances are measured prior to welding and re-calibrated prior to the welding process.
