CNC Five-Head Stirrup Bending Machine

Overview

The ZD-6M-25 CNC Five-Head Stirrup Bending Machine is a high-output rebar processing solution engineered for factories that need to turn out finished stirrups at volume. Built by Gongda in Hefei, Anhui, China, the machine combines CNC control with a five-head bending platform, allowing multiple stirrups to be produced per cycle. Pneumatic automatic locking secures the machine head during bending, which keeps the work steady and repeatable across long production runs. With a total installed power of 7.5KW and a compact footprint of 6000×1200×950mm, it fits into most rebar fabrication lines without demanding a full plant rebuild.

Key Specifications Explained

• Installed power: 7.5KW total — sized for continuous workshop operation.
• Hydraulic pressure: 5–16Mpa max; pneumatic pressure: 0.4–0.6Mpa max — the two systems work together to drive bending force and head locking.
• Head locking: pneumatic automatic locking, reducing manual intervention per cycle.
• Side length tolerance: ±2mm — a tight, consistent tolerance for stirrup geometry.
• Working temperature: -5 to 50℃ — suitable for a wide range of climates and unheated workshops.
• Bending capacity per cycle: Ø8:10 · Ø10:7 · Ø12:5 · Ø14:3 · Ø16:2 · Ø18:1 · Ø20:1 · Ø22:1 · Ø25:1 — the machine handles small diameters in multi-strand batches and larger bars one at a time.
• Minimum stirrup side length (inner diameter): 130×140mm — defines the smallest stirrup the machine can form.

Applications

The ZD-6M-25 is aimed at rebar fabrication plants, precast concrete producers, and construction supply businesses that cut and bend stirrups in-house. It suits production of column ties, beam stirrups, and similar closed-shape reinforcement where consistent side lengths and square corners matter. Because it processes bars from Ø8 up to Ø25, one machine can cover light- to heavy-duty stirrup work, reducing the need for multiple dedicated benders. The five-head configuration is particularly useful when a project calls for high daily stirrup counts rather than one-off custom bends.

Why Buy This Model from Gongda

Gongda is rooted in the electromechanical works of Hefei University of Technology, giving the brand a technical and engineering background rather than a pure trading profile. The company exports rebar processing machines worldwide, with active markets in Russia, Spain, Latin America, the Middle East, Southeast Asia, and Africa. That export experience matters for buyers who need documentation, voltage compatibility discussions, and after-sales communication in their own language. The ZD-6M-25 pairs a five-head CNC platform with pneumatic locking and a ±2mm tolerance — a practical combination for buyers who want throughput without sacrificing dimensional control.
