The first and only 4-head CNC welding machine in the world that completely eliminates the welding seam from the corner and allows you to obtain PVC windows of uniform quality and superior aesthetics.

A unique machine of its kind, it ensures perfect and simultaneous welding of 2 angles, guaranteeing absolutely flat and homogenous surfaces also with profiles that, instead of reinforcing metal, have inside them non-weldable products such as fibreglass, aluminium or resin. The DIA version allows the welding of the 4 external corners even with a pre-assembled cross beam.

5 Reasons to choose SL4-FF EVO DIA

• Versatile – White and foiled seamless welding. Aluminium clad welding.
• Efficient – One operator required. The seamless welding eliminates the need for corner cleaning.
• Labour Reduction – Not having to finish the corners, only 1 operator is required to load the profiles.
• Space Saving – Extremely compact machine (starting from just 20m²)
• Concise Welding – All profile tolerances are measured prior to welding and re-calibrated prior to the welding process.
