HAIHUI · REBAR PROCESSING GUIDE
A flat steel hoop forming machine can combine strip feeding, punching, bending and cutting. For a finished clamp or bracket, the important inspection is often the relationship between holes and bends after forming. Haihui’s HH100-20 should therefore be reviewed using the final component drawing, not only a flat-strip sketch.
What the HH100-20 reference sheet lists
The current page gives a 3–10 mm processing thickness, a 50–500 mm listed side-length range, 55 m/min maximum feeding speed and 800°/s maximum bending speed. The feeding servo is listed as 7.5 kW and the hydraulic station motor as 11 kW. Strip width, material strength and the complete geometry still require confirmation.
Dimension the component in its assembled condition
Show strip width and thickness, hole diameter, hole-to-hole distance, bend radii and the final profile. Identify whether critical dimensions are taken from a centreline, inner surface or mounting face. A hole position that is correct on a flat blank can give the wrong fit if the bend geometry or dimension reference is misunderstood.
Review punching and forming as one sequence
The offered tooling must match hole shapes, spacing, edge distances and the forming sequence. Discuss whether holes near a bend could distort and how the proposed setup will be checked. Do not assume every sample shape can be made with one die set. Ask the quotation to identify tooling included for each approved drawing.
Agree a finished-part inspection
Check hole position and profile after forming, then verify fit against the approved mating dimensions or agreed fixture. Include the first sample after a changeover and representative pieces from a batch. Record material grade, thickness, surface condition and tooling so repeat work has a traceable setup. Project acceptance limits should be agreed before production.
Compare completed clamps per shift
Nominal feed and bending speeds do not equal finished output. Hole count, hydraulic operations, forming sequence and handling all affect cycle time. Confirm inclusion of the listed electric payoff rack, consumables and optional tools. Coated strip or stainless steel needs its own application review rather than assuming the carbon-steel thickness rating applies unchanged.

Frequently asked questions
Can I buy only by strip thickness?
No. Width, material grade, holes and bend geometry affect the required configuration and tooling.
Are all sample shapes included with the machine?
Confirm individual tools and approved drawings in the quotation; sample photographs do not define the delivered die package.
