When comparing automatic rebar stirrup bender manufacturers in China, buyers usually need to review the processing range, sistema de control, output measurement, and after-sales support together. This article uses Haihui Machinery’s HH4-14S as an example and summarizes its published specifications and selection considerations for rebar processing plants and equipment distributors.
Application needs: common stirrups and batch production
For work that includes square, rectangular, and common shaped stirrups, a machine needs to feed bar consistently and maintain stable bending angles and cut lengths. Antes de solicitar una cotización, list bar diameters, common leg lengths, target output per shift, frequency of size changes, and the type of raw material supply. Give this information to the manufacturer for a configuration review instead of choosing a model from an advertised speed figure alone.
HH4-14S specifications and processing range
Haihui product information lists the HH4-14S for 4–14 mm single-wire processing and 4–10 mm dual-wire processing. The listed configuration includes a 20 kW VEICHI feeding servo motor, a 7.5 kW VEICHI bending servo motor, a XINJE PLC control system, and C&U bearings. The machine weighs approximately 1,800 kilos, and reference packing dimensions are about 4,200 × 1,300 × 2,200 mm. Confirm the packing plan for the specific order before shipment.
The manufacturer lists a reference output of about 2,000 pieces per hour for a 20 × 20 mm working condition. Actual results depend on steel grade, diámetro, forma, program, operator, and loading or unloading cycle. This reference should not be treated as stable output for every product. Before purchase, provide representative drawings or samples and ask for a test using the same specifications. Confirm whether the output count includes feeding, corte, and material changes.
Checks before putting the machine into production
- Test common production sizes and check feed length, bending dimensions, and cutting results.
- Confirm the dual-wire diameter range, material requirements, and consistency between the two bars.
- Verify servo, SOCIEDAD ANÓNIMA, inverter, and other final brands and model numbers in the order or technical appendix.
- Arrange operator training and confirm wear parts, remote support, and warranty scope.
Why confirm details directly with the manufacturer?
Speaking directly with the manufacturer makes it easier to review drawings, materials, and target output together, and to confirm lead time, packing, spare parts, and service responsibilities. Haihui Machinery can review the buyer’s bar specifications and stirrup drawings to check whether the HH4-14S fits the application. Final parameters, configuración, and quotation are subject to written confirmation by both parties.
Frequently asked questions
Can the HH4-14S process two bars at once? The product information lists dual-wire processing from 4 a 10 mm. Confirm suitability for the steel grade and product drawing.
How do I decide whether this model suits my plant? Provide common bar sizes, target output per shift, material details, and representative stirrup drawings. Ask the manufacturer to document the test conditions, configuración, and acceptance criteria.
