Cold forging
Hydraulic upsetting
The bar end is enlarged so the section after threading is not less than the parent bar. Single pass — double forging is not permitted by the standard.
Machine Services
WE MAKE BOTH HALVES OF THE CONNECTION
Most suppliers sell the coupler and leave the bar end to whoever the contractor hires. AGBA deploys the cold forging and threading machines, the tooling, the gauges and the technicians — so one quality system covers the whole connection.
What We Deploy
MACHINES, TOOLING, AND THE PEOPLE TO RUN THEM
Threading
Parallel thread
Cut into the upset region only, to the designed length and depth for the size, using AGBA tooling matched to the coupler.
Technicians
Trained to the process
Operators who know the clause, not just the machine. Gauging and proof loading are part of the job, not an extra.
Service Models
THREE WAYS TO WORK WITH US
Which one suits depends on the size of the contract, the duration, and whether the bar is being processed in a yard or at the face.
On-site deployment
Machines stationed at your site for the duration of the contract, with our technician.
- Machines and tooling supplied
- Technician deployed
- Monthly basis
- Suits sustained volume
Mobile van service
A van with the machines mounted, visiting on a scheduled day to process what is ready.
- No machine on your site
- Booked by the day
- Suits intermittent volume
- Vidarbha and nearby
Machine rental
Machines and tooling on rent where you have your own trained operator.
- Monthly rental
- Tooling supplied and consumed
- Servicing by AGBA
- Operator training available
Cold forging and threading are quoted as one combined rate per joint. Rates depend on bar size, volume and location — tell us the contract and we will quote it.
On Site
WHAT HAPPENS TO EVERY BAR END
The five steps of IS 16172:2023 Annex G-2, carried out and recorded. A manufacturer may add to them; nobody may subtract.
01
Sawn cut
Square to the axis. Disc cutting and gas cutting are named and excluded by the standard.
02
Cold forge
Hydraulically upset so the section after threading is not less than the parent bar.
03
Thread
Parallel thread cut into the upset region only, to the designed length and depth.
04
Gauge
GO and NO-GO on every end. A failed thread is cut off and the bar reprocessed.
05
Proof load
Loaded to 80% of specified yield and machine punched on passing.
Threads are capped and protected until the next bar is offered up. A signed service slip is raised for every visit, with quantities by size, for your records and ours.
