TheUPVC PVC Windows Double Head Seamless Welding Machine is a double head seamless welding machine designed for PVC, UPVC, plastic, and vinyl window and door profiles. It integrates welding and automatic bead cleaning into one operation, delivering a smooth, premium surface finish while achieving welding strength higher than traditional methods.

Key capabilities include:

Seamless welding & cleaning – Completes welding and bead removal in one step, strictly controlling seam size. Ideal for colorful section steels, producing a top-grade appearance.

Advanced pneumatic control – Enhances welding strength through software-processed melt-welding clearance and welding cycle. Parameters are digitally adjustable to maintain optimal strength across different environments.

Standardized, interchangeable cutter – Made of special material with heat treatment and precision finishing. Fully standardized for easy replacement without a professional technician.

Integrated window-support welding – Uses eight cutting tools to weld and clean corners and seams simultaneously. Supports low-seam clearing for standard and crossed window-support profiles, ensuring perfect surfaces and high strength.
