4 HEAD WELDING MACHINE
4 HEAD WELDING MACHINE - AWGTECH - AT4K
4-Head CNC Welding Machine
Innovative TVF Technology · PVC & PVC-ALU Profiles
The AT4K is an innovative four-head welding machine designed for window and door profiles, incorporating four advanced industrial technologies. Built for full automation of the welding process, it delivers a significant step up in both production efficiency and joint quality. The proprietary TVF (Thermo-Vibro-Form) technology compacts the welded material during joining, eliminating gas bubbles from the PVC melt and producing welds up to 30% stronger than conventional machines.
