When a rebar-processing plant plans an equipment upgrade, common goals include reducing manual straightening, измерение, and bending steps and making stirrup production more continuous. This selection guide uses the HH4-14S product information to explain how a buyer can review order mix, bar range, workshop space, and acceptance criteria. It is a general planning example rather than a record of a specific customer’s purchase. Actual performance should be verified under the intended site conditions.
Identify the production bottleneck first
An upgrade decision should not rely on theoretical speed alone. Review recent orders and group them by bar diameter, stirrup shape, frequency of size changes, and causes of rework. Measure the time spent on existing cutting, изгиб, and material transfer. If the main problem is repeated handling or manual positioning, review the feeding, length setting, program change, and finished-product collection processes. If orders include sizes outside the machine’s range, confirm how those jobs will be handled before selecting equipment.
Check the HH4-14S model and configuration
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, а 7.5 kW VEICHI bending servo, a XINJE PLC control system, and C&U bearings. The machine weighs approximately 1,800 кг. Reference packing information is approximately 4,200 × 1,300 × 2,200 мм; confirm the actual packing dimensions and weight for the order before dispatch.
Product information gives a reference output of about 2,000 pieces per hour for a 20 × 20 mm working condition. Compare that reference with your own drawings and confirm the bar diameter, stirrup dimensions and shape, test duration, and acceptance criteria. Program complexity and loading arrangements affect actual output, so use a continuous sample test as the basis for production planning.
From installation planning to trial production
- Send representative drawings and bar specifications for written confirmation of the application range.
- Check machine dimensions, feeding direction, power supply, infeed and outfeed space, and safety access.
- Test common sizes and record accepted output, dimensional variation, rejects, and changeover time.
- Before acceptance, confirm the brands and configuration, included spare parts, обучение операторов, warranty scope, and service contacts.
How to evaluate the upgrade
If daily orders are mostly within the machine’s range and labor constraints come from repeated feeding and bending, an automatic CNC rebar stirrup bender may be worth comparing as an upgrade option. Calculate payback using shifts, staffing, material costs, workshop space, and order stability. A single speed figure should not be treated as a profit guarantee. When contacting a China automatic rebar stirrup bender manufacturer, request a demonstration or test record using bar and drawings that match your actual work.
Frequently asked questions
What information should we prepare before upgrading? Prepare bar diameters and grades, typical stirrup drawings, expected output, workshop layout, and power supply details.
Are the packing dimensions fixed? The approximately 4,200 × 1,300 × 2,200 mm figure is a reference. Use the packing list confirmed for the specific order.
