This fully automatic rebar bundling machine delivers fast, consistent ties and simple operation for construction, metal processing, and packaging tasks. Its portable, battery powered design and adjustable controls make it suitable for a wide range of bundle sizes and materials. Key benefits Fast and consistent tying: completes a knot in 0.8 seconds for productivity on repetitive tasks. Long runtime per charge: two 5000mAh batteries provide extended use; a single full charge can tie approximately 3500 rebars. Precise tension and turn control: an upgraded LED screen shows digital settings from 1 to 10 so you can set both the number of turns and tightness from loose to tight. Versatile clamping and compatibility: designed clamping force and structure easily clamp and bundle rebars, aluminum ingots, and various packaging materials. Portable and easy to use: lightweight, compact body with a simple outlet switch to pull out wire and set the required tension and turns. Key specifications Bundling range: 4 to 45 mm / 0.16 to 1.77 in Wire diameter: 0.8 mm / 0.03 in Knot speed: 0.8 seconds per knot Batteries: 2 x 5000 mAh Runtime estimate: about 3500 rebar ties per full charge Charging time: 50 to 80 minutes Wire roll length: 95 m / 3740 in Ties per wire roll: about 180 knots Adjustment: LED screen with digital 1 to 10 gear selection for tightness and number of turns How it solves common problems Reduces manual labor and fatigue by automating the tying motion and delivering rapid, repeatable knots. Improves quality and consistency of bundles through adjustable tension and turn settings shown on the LED screen. Minimizes downtime with fast charging and long battery life for continuous work onsite. Fits a wide range of bar diameters and other materials thanks to the broad bundling range and robust clamping design. Typical applications Construction sites: tying rebar for foundations, columns, beams, and prefabricated cages. Metal processing and foundries: bundling aluminum ingots and metal stock for handling and transport. Packaging and logistics: securing grouped materials for storage and shipment. Operation notes Press the outlet switch to extend the wire, select the desired gear setting on the LED screen for tightness and turns, then position the tool and activate the knot cycle. the wire roll when the 95 m spool is depleted; each roll yields about 180 knots. Charge both batteries fully in 50 to 80 minutes to restore full runtime. This rebar bundling machine offers a balance of speed, adjustability, and portability for professionals who need reliable, repeatable ties across a range of materials and bundle sizes.
