  • Three Head UPVC Seamless Welding Machine for PVC Window and Door

    Three Head UPVC Seamless Welding Machine for PVC Window and Door

    The 3-Head Seamless Welding Machine for PVC / UPVC Doors and Windows​ is designed for one-cycle welding of three corners (e.g. "┌┬┐" shape) on vinyl window and door frames. Each head integrates heating, pressing, fixing and automatic seam-cutting, so the welded corner is smooth on both surfaces without secondary cleaning—especially suited for co-extruded colored profiles. Three heads can work independently or in combination; one head supports variable-angle (30°–180°) welding for arch windows. Controlled by PLC with touch screen for heating/pressing/cooling time setting, pneumatic clamping ensures repeatable ±0.2mm seam accuracy.
