Automatic Spiral Bending Machine Manufacturer in India
Dhanshree Engineering designs and manufactures high-precision automatic spiral bending machines for rebar rings, helical spirals, and circular stirrups used in RCC columns, piles, tunnels, and precast elements. Built for continuous production and dimensional accuracy, our machines combine servo/CNC control, robust gear trains, and operator-friendly HMI to deliver repeatable results with minimal scrap and low maintenance.
Working Principle and Process Flow
Coils or cut bars are fed to the straightening and guiding unit, then driven by synchronized rollers toward a programmable mandrel. The bending head forms spirals or rings to the target diameter, pitch, and turn count. Closed-loop encoders monitor length and angle in real time, while auto-cutting shears complete each cycle. The integrated control stores multiple recipes, enabling quick changeovers across diameters and grades.
Machine Range
- Automatic spiral bender with programmable pitch and diameter memory.
- CNC ring making machine for rebars and mild steel rounds.
- Dual-drive spiral bender for heavy sections and larger diameters.
- Compact ring former for precast plants and on-site fabrication.
- Custom mandrel systems for special radii and thin-wall rods.
Key Features and Specifications
