4-Corner Seamless Corner Rounding Welder with Adjustable Radius R1-R10mm for Stainless Steel Door & Window Frames Featuring Synchronous Welding and Seamless Joints

1. 4-Corner Synchronous Welding:Designed specifically for stainless steel door/window frames, it enables simultaneous seamless rounding of all 4 corners (R1-R10mm adjustable). This eliminates uneven joints, ensuring consistent aesthetics and structural integrity across the entire frame.
2. Seamless Joint Advantage:Adopts high-frequency pulse welding tech to create gap-free, burr-free welds. The seamless connections boost the frame’s water tightness and wind resistance, critical for outdoor or high-humidity applications like bathroom windows or balcony doors.
3. CNC Precision & Efficiency:Equipped with a CNC system and frame positioning clamps, it achieves ±0.04mm precision. Presets for 20+ common frame sizes (e.g., 800×2000mm doors, 1000×1400mm windows) cut setup time by 60%, ideal for batch production.
4. Stainless Steel Optimization:Tailored for 304/316 stainless steel, it prevents weld oxidation via inert gas protection. The machine’s anti-rust torch and steel frame ensure long-term use in busy door/window manufacturing workshops.
