Automatic Stirrup Bending Machine: Complete Price & Buying Guide (India)

What Is an Automatic Stirrup Bending Machine?

A PLC or CNC-controlled machine that converts coiled or straight rebar into finished stirrups — the reinforcement cages used inside beams, columns, and slabs. Used across construction sites, precast plants, and infrastructure projects to improve productivity, cut labour costs, and ensure uniform bending quality, from residential columns to bridges and metro flyovers.

How Does an Automatic Stirrup Machine Work?

1. Feeding — coiled rebar is pulled through a servo-driven traction system
2. Straightening — horizontal and vertical units remove the natural curl
3. Measuring — sensors track exact length to define cut and bend points
4. Bending — a servo-driven arm bends the bar to the programmed angle (up to 180°)
5. Cutting — a synchronized cutter trims the piece to length
6. Collection — finished stirrups drop onto a collector

On CNC machines, the operator enters stirrup dimensions via an HMI, and the machine handles the rest automatically — no manual measuring or repositioning.

Automatic Stirrup Machine Price in India

Real listings: basic automatic units start ₹18,803–₹30,000; a machine rated 1,800–2,200 pcs/hour on 8mm bar runs ~₹6,50,000; CNC benders with 0–50mm capability go around ₹13,50,000, with top-tier CNC lines reaching ₹22,31,000+.

Which Brands Sit in Each Tier

The price bands above span everything from small domestic workshop units to imported European precision lines — and that's really the main driver of cost, not just capacity numbers.

Rule of thumb: entry-level and most mid-range machines on the Indian market are domestic (Sona, TKD) or Chinese imports (TJK). The heavy-CNC tier is where European brands — MEP, Schnell, Pedax, Progress — dominate, and where spare-parts lead time and service network reach (often shipped from Europe) matter as much as the sticker price. Sona is the exception that spans the full range — its GW-series sits at entry-to-mid, while the D2N and D4 compete directly with the European heavy-CNC names.

Common Machines Available in India

Sona D2N

India's compact CNC stirrup bending machine, positioned at the heavy-duty end of the domestic lineup.

Sona D4

Sona's higher-capacity CNC model, built for larger fabrication and precast volumes.

TJK (India)

Chinese-made CNC stirrup benders sold through Indian import/trade dealers, spanning mid-range to heavy CNC.

MEP

Italian coil-processing and cut-and-bend machines, distributed in India through authorized dealers.

Schnell S.p.A.

Italian high-speed CNC stirrup benders, aimed at large precast and infrastructure contractors.

Progress Machine

Italian precast-line equipment supplier, typically part of a larger rebar-processing setup rather than sold as a standalone unit.

Production Capacity — Rings/Hour

• Entry-level: 300–500 rings/hour
• Mid-range: 500–800 rings/hour (some up to 1,800–2,200 on smaller diameters)
• High-end CNC: 2,300+ rings/hour, bending speeds up to 1,450°/sec

Always confirm rated output at your actual bar size — headline numbers are usually best-case, at the smallest diameter.

Wire Diameter & Material Compatibility

• Entry-level: 4–14mm
• Mid-range: 6–16mm
• Heavy CNC: up to 6–32mm

Most machines process both cold-drawn and hot-rolled stock, covering standard MS and TMT rebar. Check the range against your actual project mix — a 6–32mm machine is wasted spend if 90% of your work is 8–10mm.

Power Consumption

Average draw: 2–10 kWh depending on model; larger CNC motors are rated up to 25–26kW but draw less than peak during normal cycles.

Estimated cost at 5 kWh average and ₹8/unit: ₹40/hour → ₹320/day → ~₹8,000/month — a small fraction of labour savings, but worth budgeting.

Labour Requirement

• Manual: 2–4 workers per station
• Automatic (entry/mid): 1 operator, occasionally +1 helper
• High-end CNC: 1 operator can match 3–4 manual workers' output; large lines are marketed as replacing 20–30 workers in high-volume settings

Beyond wages: less recruitment overhead, lower injury risk, less dependence on scarce skilled labour.

Automatic vs Manual Stirrup Making

Manual bending still suits very small or occasional jobs — no electricity needed, fully portable, low learning curve. For regular volume, automation's consistency and labour savings typically win within a year.

ROI Calculation With Example

Mid-range ₹1,50,000 machine, replacing 2 workers (₹1,200/day) with 1 operator (₹600/day):

• Daily saving: ₹600 → Monthly: ₹15,000
• Payback: ~10 months

Add 3–5% material savings from reduced wastage, and realistic payback lands 8–14 months. High-volume CNC lines pay back relatively faster despite higher upfront cost, given the larger labour offset. Low, irregular volume breaks this math — an idle ₹1,50,000 machine won't pay for itself; a ₹20,000–40,000 entry unit fits better there.

Who Should Buy an Automatic Stirrup Machine?

• Precast plants with continuous high volume → heavy CNC tier (MEP, Schnell, Pedax, Progress, top-end TJK, Sona D2N/D4, TKD)
• Fabrication yards supplying multiple sites → mid-range tier (Sona GW-series, TJK)
• Mid-large contractors with steady in-house needs → mid-range, sized to typical bar diameter
• Small/occasional fabricators → entry-level unit (Sona GW-series) or manual bending

How to Choose the Right Machine

• Match bar diameter range to what you actually use most
• Confirm capacity at your bar size, not the headline number
• Match automation grade to labour availability and volume consistency
• Verify after-sales service reach before buying — especially critical for imported CNC brands (MEP, Schnell, Pedax, Progress) where spares may ship from Europe
• Get warranty terms in writing
• Budget installation and training into total cost, not just sticker price

Common Buying Mistakes

• Buying on price alone without checking diameter/volume fit
• Trusting best-case capacity figures
• Skipping after-sales support checks
• Oversizing the machine beyond actual production mix
• Deciding on specs before running the labour/ROI math
• Leaving installation and training costs out of the comparison

FAQs

Minimum price in India?

Entry-level units start ₹18,000–30,000 (see Price section for full breakdown).

Which brands are common in India?

Sona (GW-series through D2N/D4) and TKD dominate the domestic side; TJK covers mid-to-heavy CNC as a Chinese import; MEP, Schnell, Progress, and Pedax are the main European heavy-CNC brands for precast-scale operations.

How many workers does it save?

Typically 2–3 manual workers replaced by 1 operator; see Labour Requirement above for CNC-scale savings.

Payback period?

8–14 months for most mid-range machines — full calculation above.

Bar diameters supported?

4–32mm depending on tier — confirm against your project mix (see Wire Diameter section).

Worth it for small contractors?

Only with regular, reasonably high volume — otherwise an entry-level unit or manual bending is more cost-effective.

Electricity cost?

Roughly ₹8,000/month for a mid-range machine — small relative to labour savings.

Conclusion

The right machine matches your actual bar diameter, volume, and labour situation — not the biggest capacity number, and not just the cheapest brand. Domestic units (Sona's lower GW-series, TKD's entry range) suit small-to-mid needs; heavy CNC lines — whether domestic (Sona D2N/D4) or imported (MEP, Schnell, Pedax, Progress, TJK) — suit high-volume precast operations where speed, precision, and multi-shape flexibility justify the premium and, for imports, the longer parts-supply chain. Get that fit right and the 8–14 month payback and ~₹8,000/month running cost hold up in practice.
