Our Automatic Stirrup Bending Machine is controlled by CNC with Automatic Wire Feeding System. Split, Multi Blade Design (Patented) to reduce consumption costs. Our One single machine contains straightening, stirrup bending & cutting. It can automatically straighten, bend and cut bar wire instead of 20~30 workers & it reduces too much cost. It can produce 1200~1300 Rings in a hour in comparison to traditional method to make bar ring where you can only make 1200~1300 rings in 12 hour shift also compromising the accuracy and consistency. Our Automatic Stirrup Production Capacity 230-320 Tons 10 Hour per Day x 2 shift for 26 Days in a month. In today's world where projects are time bound. Our Automatic Stirrup Machine is right Choice for them.  Our Stirrup Bender can edit any 2D Shapes with Max. 50 Angles, the data base can store more than 500 shapes. Different shapes can be processed continuously without stop, furthermore no need to stop the processing while adjusting the bending angle.
