A rebar threading machine should be ordered with tooling matched to the bar and coupler specification. Haihui lists HGS40 and HGS50 models with different published bar ranges. A complete tooling list makes the enquiry more useful than selecting by motor power or model number alone.
Start from the coupler specification
Provide the coupler drawing, nominal bar diameter, thread pitch, thread length and required engagement. Identify each connection system that the workshop intends to process. The same bar diameter does not by itself establish that two couplers need identical thread preparation or inspection.
Shortlist the published machine range
Haihui lists HGS40 for 16–28 mm bar with a 4 kW motor. HGS50 is listed for 16–40 mm bar with a 7.5 kW motor and an 80 mm processing length. For bars above 28 mm, discuss HGS50 rather than inferring a larger HGS40 range from its name. Material grade and tooling still need confirmation.
List included and additional items
Ask the supplier to identify rollers, related preparation tools, gauges, spare wear parts and any couplers separately. State which items are included for each approved thread size. Confirm how a changeover is performed and what setup guidance will accompany the machine.
Approve a representative thread sample
Use the intended material, tooling and coupler specification in the trial. Inspect the finished thread using the agreed method and record the setup. Machine operation alone does not certify a structural connection: any connection tests and project approval requirements remain separate. Include bar handling and inspection when reviewing workshop output.
Frequently asked questions
Is HGS40 listed for 16–40 mm rebar?
The current Haihui HGS40 sheet states 16–28 mm. The HGS50 sheet states 16–40 mm, subject to configuration and application review.
How can I request a factory quotation?
Send dimensioned drawings, material grade and sizes, required quantities, local power supply and the destination country. Ask Haihui to confirm configuration, accessories, inspection requirements and delivery terms in writing.
