Haihui HH4-14S CNC rebar stirrup bending machine — Haihui HH4-14S machine illustration. Final configuration is subject to the agreed quotation.

Diameter is only one selection input

Two coils with the same nominal diameter can behave differently during straightening and bending. A CNC stirrup bender quotation should therefore identify more than the largest advertised bar size. Tell the manufacturer which material grades you buy and provide available mill information, along with the diameter range.

Describe the incoming coil

Include whether the material is round or deformed, its coil dimensions and weight, and how it will be handled in your workshop. Surface condition and variation in the incoming material can affect setup and finished results. A machine demonstration should use material representative of the stock you plan to process.

Separate single-wire and double-wire requirements

Do not apply a single-wire capacity statement automatically to double-wire work. Ask the factory to confirm the proposed configuration for both modes and for your actual grade. If double-wire production is important, include matching-coil handling, sample shapes and measurement of both finished pieces in the trial plan.

Agree on a material-based trial

Xingtai Haihui Machine Tool Co., Ltd. can discuss model selection from your stated production requirements. Send photos, material details and drawings together. Ask the factory which information remains unconfirmed before accepting an offer. This makes the final technical scope easier for your operator and purchasing team to understand.
