SL5 UNI

Universal 5-Head CNC Welder for Variable Angles and Multiple Joints

Maximum flexibility: one machine for all window frame welding configurations

Perfect if:

Produce complex frames with multiple welded crossbars at the same time.
You need variable configurations (angles, crosses, “T”, “H”) with a single machine.
Do you want to reduce cycle times with combined multi-welding?
Are you looking for a modular and reconfigurable welder depending on the job?
You work with film-coated or painted profiles, even with irregular tolerances.
Do you want to automate the process without sacrificing operational flexibility?

Maximum flexibility: a single machine for all window frame welding configurations

The SL5 UNI is an extremely versatile 5-head CNC welder designed for complex machining and special configurations. It can simultaneously weld 90° angles, T-joints, cross joints, or H-joints, as well as variable angles between 35° and 180°. A dedicated selector allows it to be used as two distinct machines: a dual-head and an independent triple-head, optimising combined cycles. The cycle is fully automated, and the management technology ensures precision, stability, and repeatable quality across all types of profiles.
