CNC 4-head welding machine

4-head CNC welding machine with 3 controlled axes, designed for horizontal and simultaneous welding of the 4 corners of a Pvc frame; ensures the frame manufacturer with constant operating quality over time.

It automatically performs all the necessary operations, positioning at the welding positions, cyclical fusion, compression and cooling and, at the end of the process, it releases the frame on conveyor belts towards the cleaning area.


5 Reasons to choose the SL4-U

It divides the cutting offsets of the profiles on all 4 welding corners.

Electronic temperature control combined with the profile code.

High technology for maximum precision: Movements on linear guides and rack.

Quick replacement system for welding countershims.

User Friendly technology.
