The aesthetic revolution in PVC welding
The SL4FF EVO RS is the world’s first and only CNC welder with 4 heads that can completely eliminate the bead from the corner, achieving a perfect, flat, and uniform weld even on difficult or unsolderable profiles.
Equipped with patented V-Perfect technology and an advanced axis control system, it ensures precision, speed, and superior aesthetic quality, all without the need for cleaning or touch-ups. Everything is done automatically, all in a single cycle.
5 Reasons to Choose SL4FF EVO RS
- Perfect on every material. Painted, coated, acrylic, wood or aluminium laminates: it bonds everything without leaving a bead.
- Optimized cycle time. Up to 1 full frame every 80-140 seconds* without additional processing.
- Minimal Labour. Only 1 operator is needed: the welding process is fully automated.
- Compact structure. Reduced layout: starting from just 25 m², even for special configurations.
- Automatic Tolerance Compensation. Integrated system for correcting cutting errors of up to 2 mm and height misalignments of up to 0.5 mm. (*depending on the type of profiles and seals)
