■ Designed for seamless welding of rectangular frames (or sashes) and mid-rails of plastic doors and windows.

■ After welding, this machine completes the cleaning of welding beads in one go, allowing strict control of welding gap size. The welded joints of colored profiles are aesthetically pleasing and high-end, with welding strength higher than that of the original profile angles.

■ Through control and pneumatic systems, this machine enhances welding strength by addressing modes such as melting, gap filling, and software processing during the welding process, ensuring optimal welding strength in different environmental conditions and enabling quantitative adjustments through digital parameters.
