This HH4-12S CNC rebar bending machine case record summarizes the Zhejiang Zhengchi project and the information available on the published page.
Case summary: Haihui’s case archive records an order for one CNC steel bar bending machine, model HH4-12S, for a Zhejiang Zhengchi construction project. The archived product entry includes machine parameters, but specifications can change by configuration and revision. Buyers should use a current signed technical offer to confirm operating limits and included equipment.
Recorded project information
The archived case names the Zhejiang Zhengchi Construction Project and identifies the ordered machine as an HH4-12S CNC steel bar bending machine. The public page lists a single-machine order. It does not describe the project’s final installation date, production volume, or field results.
Archived machine data
The old case page includes power figures for the straightening, изгиб, flying-knife cutting, and air-pump motors, as well as separate processing ranges for round and threaded bar in single- and double-line modes. Because legacy listings can reflect a particular configuration, those figures should not be treated as a universal HH4-12S specification. Ask Haihui to confirm the latest model designation, wire range, output assumptions, and electrical supply for your own order.
How to compare this model for a new project
For a construction or rebar fabrication project, prepare the dimensions and bend details of your regular stirrups, the bar diameters and grades, the expected output per shift, and the factory voltage, phase, and frequency. Ask for a drawing-based cycle estimate and a written list of accessories, training, ввод в эксплуатацию, warranty, and spare-parts arrangements. If comparing the HH4-12S with a current model such as HH4-14S, compare each model against the same bars and drawings.
The public Zhengchi case establishes the order and model name; it does not publish a verified production outcome. This article does not infer one.
