PVC Window Door Making Single Head Double Side Seamless Welding Machine
The PVC Window Door Making Single Head Double Side Seamless Welding Machine is a premium solution for manufacturing high-end white and colored UPVC doors and windows. Equipped with a single machine head that houses four precision cutters, it achieves flawless double-sided seamless cleaning on both top and bottom surfaces. Driven by a top-level Omron PLC and guided by precision square rails, this machine guarantees exceptional welding strength and a perfectly smooth finish. With versatile angle welding capability (30°–180°) and customizable features, it supports on-demand component matching and extended spare parts supply cycle, making it the ideal choice for producing standard, arc-shaped, and custom-designed PVC windows for global merchants.
Built by Lebulang Machine — a China-based manufacturer with close to 30 years of factory experience in window and door processing equipment — this single-head double-side seamless welding machine is CE and ISO certified. It is supplied factory-direct and can be configured to OEM and ODM requirements.
Instead of welding and cleaning in separate steps, the machine completes both actions in one automatic cycle. Four quenched alloy cutters trim the weld bead from both sides of the joint as the profile cools, leaving colored, co-extruded, and laminated UPVC/PVC surfaces smooth without visible weld lines. An Omron PLC manages heating time, pressing time, and cooling time through a color touchscreen, keeping joint size and strength consistent across production runs. After cleaning, an automatic blowing function removes the cut slag from the work area, cutting down on manual cleanup between cycles.
Square precision guide rails carry the welding head through its motion, and the head’s air pressure can be adjusted independently to suit different profile sections. Angle capability spans 30° to 180°, so the machine handles standard 90° corners as well as arcs, bays, and custom polygon frames. Quick-detachable molds reduce changeover time when switching profile types.
The machine accepts profile heights and widths from 20 to 120 mm and welding lengths from 450 to 3500 mm. It runs on a 220V single-phase supply, draws 1.5 kW, and needs 0.5–0.7 MPa working air pressure. Overall dimensions are 800 × 1100 × 1800 mm, and the unit weighs approximately 300 kg. Remote installation guidance is included at no additional charge.

FAQ
Q1: What types of profiles is this seamless welding machine suitable for?
A: The machine is specifically designed for high-end white and colored UPVC/PVC profiles. The double-side seamless cleaning ensures that colored or laminated surfaces remain perfectly smooth and aesthetically pleasing without visible weld lines.
Q2: How does the machine ensure the longevity of the cutting blades?
A: The machine utilizes four cutters made of high-quality alloy that have been precisely quenched. This advanced heat treatment significantly extends their service life, and their standardized size makes replacement quick and cost-effective.
Q3: Can this machine process arc-shaped or custom-angle windows?
A: Yes, absolutely. Unlike standard 90-degree welders, the machine can weld any angle between 30° and 180°, making it highly versatile for manufacturing arc-shaped doors, windows, and special architectural designs.
Q4: How is the welding quality and size controlled?
A: The machine adopts a top-level Omron PLC combined with a color touch screen. This allows operators to precisely set and monitor parameters such as heating time, pressing time, and cooling time, ensuring accurate weld size and consistent strength.
Q5: Does the machine require manual cleaning of the welding slag?
A: No, the machine features an automatic blowing function that effectively blows off the cut welding slag immediately after cutting. This reduces manual labor and speeds up the overall production process.
Q6: What is the maximum profile height this machine can handle?
A: The standard welding height range is 20 to 120mm. However, the machine can be customized to accommodate higher profiles based on your specific production requirements.
Q7: How precise is the movement of the welding head?
A: The entire motion structure adopts square precision guide rails. This advanced mechanical design ensures high-precision alignment and exceptionally smooth operation during the welding and cleaning cycles.
