The versatile solution for out-of-square profiles, with precise welding from 35° to 180°.
The SL2V E is a dual-head welder – one fixed and one movable with variable angle – developed by GRAF Synergy to meet the most complex production needs in the PVC window and door sector.
It is capable of welding single angles from 35° to 180° or two 90° angles in a single cycle, providing versatility, robustness, and maximum geometric precision even on out-of-square or “C” shaped elements.
Equipped with electronic temperature control, digital controls, and quick replacement of templates, the SL2V E represents a strategic investment for those seeking reliability, operational flexibility, and consistent quality.
5 reasons to choose SL2V E
- Uncompromising versatility. It allows welding on non-orthogonal angles (from 35° to 180°), making it perfect for special frames.
- Precise and consistent edge. Adjustable limit knives from 0.2 to 2 mm: aesthetic quality even on complex profiles.
- Electronic temperature control. Intelligent temperature management for consistent results over time.
- Simple and intuitive operation. Digital controls and automatic cycle: a single operator can manage the entire process.
- 5. Quick Replacement of Counter Templates. Fast and error-free format change system.
