Fully Automatic Rebar Bundling Machine Key benefits Speeds up tying tasks with automatic knotting in 0.8 seconds per knot, increasing productivity on site. Portable, battery powered operation removes the need for cords and enables use across multiple work areas. Adjustable tension and turn count let you tailor each bundle for rebar, aluminum ingots, and packaging materials to ensure secure fastening without damaging materials. Compact, easy to handle design reduces operator fatigue and simplifies operation for crews of any experience level. Main features and specifications Bundling range: 445 mm / 0.161.77 in, suitable for common rebar sizes and similar stock. Power: two 5000 mAh batteries for extended runtime. Battery performance: can bundle about 3500 rebars on a single charge; charging time 5080 minutes. Wire: diameter 0.8 mm / 0.03 in; wire roll total length 95 m / 3740 in; one roll can tie about 180 knots. Speed: 0.8 seconds per knot for fast, consistent tying. Clamping: strong clamping force and a specially designed structure enable reliable grip and alignment of rebars, aluminum ingots, and packaging bundles. Controls: upgraded LED screen with digital adjustment of 1 to 10 gears; tightness settings 1 to 10 from loose to tight for precise tension control. Operation: lightweight and compact; press the outlet switch to feed wire, then set tension and number of turns according to the application. How it solves common problems Eliminates repetitive manual tying, reducing labor time and physical strain. Provides consistent knot quality and tension, reducing rework from loose or uneven ties. Battery operation and fast knotting minimize downtime and keep workflow moving across different areas of a site or . Practical use scenarios Construction foundations and column reinforcement: quickly tie rebar intersections during formwork and reinforcement assembly. Metalworking and foundry handling: bundle aluminum ingots or stacked metal pieces for storage and transport. Warehouse and packaging operations: secure packaged materials and palletized goods where quick, repeatable ties are required. User tips Select an appropriate tightness gear based on material thickness and required hold. wire rolls before they run out to avoid interruptions; one roll yields about 180 knots. Keep batteries charged and follow the 50 to 80 minute charging time to maintain continuous operation. This fully automatic rebar bundling machine combines speed, adjustable control, and portability to handle rebar, aluminum ingots, and packaging materials efficiently and consistently.
