SLS
Single-head CNC welder for PVC thresholds and special profiles
V-Perfect welding on any type of coating, without cleaning or reworking
Perfect if:
- You need to weld visible thresholds or corners where aesthetics are essential.
- Use film-coated or painted profiles that cannot be reworked.
- Do you want to completely eliminate the post-welding cleaning phase?
- You work with non-weldable materials inside the profiles (fibre, metal).
- You need a compact solution, perfect for small spaces as well.
- Do you want to maximise automation while maintaining flexibility in your components?

V-Perfect welding on any type of coating, without cleaning or reworking
SLS is the world’s first single-head CNC welder specifically designed for the perfect junction of thresholds between walls and frames. Thanks to the exclusive V-Perfect technology, patented by Graf Synergy, it completely eliminates the welding bead, achieving flat and uniform surfaces without the need for finishing. The machine is ideal for working with complex profiles, whether painted or laminated, featuring non-weldable internal inserts (fibreglass, aluminium, resin), offering maximum production flexibility with just one operator.
5 reasons to choose SLS
- Perfect welding, without seams or touch-ups. Thanks to V-Perfect technology, the welded angle is clean, uniform, and free of visible joints, even on decorative or coated profiles.
- Compatible with all types of coatings. Anodised aluminium, painted PVC, natural wood, acrylic: SLS guarantees the same precision and finish on every material.
- Significant reduction in production time and costs. No rework, no cleaning, no parts rotation table: a complete cycle every 140 seconds with just one operator.
- Compact size, maximum efficiency. Just 3×3.5 metres: the machine is ideal for compact production layouts, without compromising on performance and quality.
- Automatically compensates for tolerances. An intelligent automatic calibration system that adjusts the cycle to the dimensional differences between profiles, maintaining impeccable aesthetics.
Product Details
SLS was created to meet the needs of those who produce high-quality aesthetic windows. Every weld is perfectly integrated into the profile, even when dealing with complex materials and delicate coatings. The result: designer windows ready without any additional steps.
