CNC Rebar Stirrup Machine for Sale: What to Look For Before You Buy

CNC Rebar Stirrup Machine for Sale: Key Differences Between Single-Head and Five-Head Models

When you search for a cnc rebar stirrup machine for sale, the first major decision is between a single-head and a five-head machine. A single-head machine (like the Gongda GW25) bends one stirrup at a time, which is ideal for small workshops or projects with varied stirrup sizes. In contrast, a five-head machine (such as the ZD-6M-25 or ZD-6M-20) bends multiple stirrups in one cycle, dramatically increasing productivity for high-volume production. For a rebar fabrication plant or precast facility, a five-head model can reduce labor and cycle time, but it requires more floor space and a higher initial investment. Assess your daily output needs: if you produce thousands of identical stirrups, a five-head machine pays off; if you handle many custom shapes, a single-head offers flexibility.

Stirrup Bending Machine Price: What Drives the Cost?

The stirrup bending machine price depends on several factors, not just the number of heads. Key cost drivers include bending diameter capacity, automation level, and locking mechanism. For example, the ZD-6M-20 features hydraulic automatic locking and an 8 kW installed power, while the ZD-6M-25 uses pneumatic locking. Hydraulic systems typically cost more but provide stronger clamping for larger bars. Also, consider the maximum bending diameter: the GW25 handles round steel up to 25 mm, while the five-head models may have different limits. Higher automation (e.g., CNC controls, automatic feeding) raises the price but reduces operator skill requirements. Instead of asking for a fixed price, request a quote based on your specific rebar sizes and production volume. Many suppliers, including Gongda, offer tailored packages.

Buying Checklist: What to Verify Before You Buy

Before you commit to a buy stirrup bender, use this checklist:

• Bending diameter range – Ensure the machine covers your rebar sizes (e.g., up to 25 mm for GW25).
• Number of heads – Match it to your required output per cycle.
• Locking system – Pneumatic (ZD-6M-25) vs. hydraulic (ZD-6M-20) – choose based on bar rigidity and speed.
• Power and energy consumption – Check installed power (e.g., 8 kW for ZD-6M-20) to plan electrical setup.
• CNC control – Look for user-friendly programming and memory for multiple stirrup shapes.
• After-sales support – Verify spare parts availability and technical support from the exporter (Gongda, based in Hefei, Anhui, China).

Also, ask for a video demonstration and a detailed spec sheet. Compare the footprint and maintenance requirements. For high-volume production, a five-head machine like the ZD-6M-25 or ZD-6M-20 is a solid investment, but for small batches, the GW25 offers precision and speed.
