YG rebar thread rolling machine covers five standard models for processing steel bars ranging from 5mm to 80mm. Adopting cold extrusion forming technology instead of traditional cutting processing, it extrudes complete thread profiles by physical metal deformation without producing metal scraps, raising raw material utilization to nearly 100%. Equipped with stable hydraulic driving systems and high-hardness alloy rolling wheels, the equipment ensures uniform thread precision and higher tensile strength of finished workpieces. Adjustable spindle speed and tilt angle support metric, imperial, and special threads for rebars, anchor bolts, and auto fasteners. The whole unit runs steadily with low failure rates, and optional automatic feeding structures boost production efficiency greatly. Widely applied in construction, automobile, and hardware manufacturing industries, it effectively cuts production costs and improves finished product quality for global processing factories.

Case Study 1: Auto Fastener Manufacturing Factory, Central Mexico
Customer Background
This medium-sized manufacturing plant located outside Mexico City has 32 full-time production workers, supplying automotive bolts, suspension studs, and hydraulic pipe threaded connectors to local car assembly plants and auto repair wholesalers across central Mexico. Its core raw materials are medium carbon steel bars ranging 8–42mm in diameter, with a daily output target of 6,500 threaded workpieces. Before purchasing our equipment, the factory ran outdated lathe tapping machines and cheap low-pressure thread rolling machines from local suppliers, facing constant quality and output bottlenecks.
Original Difficulties
- Old low-pressure rolling equipment only reached a maximum 90KN pressure; thick 38–42mm steel bars produced incomplete, shallow threads, with reject rate hitting 14% and lots wasted every day.
- Lathe cutting technology generated massive steel scraps, wasting around 13% of raw steel monthly, raising material expenditure heavily.
- Slow spindle rotation limited hourly output to only 260 pieces; large OEM orders often extended delivery time by 7–10 days.
- Thin rolling wheels wore out within 10 working days; monthly spare part replacement cost reached 1,850 MXN.
- Unstable spindle angle caused inconsistent thread pitch, failing inspection standards of local auto OEM buyers and risking long-term supply contracts.
Customized Solution
We recommended a YG28-80 hydraulic thread rolling machine matching their 6–42mm processing range. Core parameters: max rolling pressure 150KN, processing diameter 6–42mm, rolling wheel diameter 120–170mm, 5.5kw main motor, spindle speed 36–78r/min, total weight 1700kg. We provided Spanish operation manuals, 3 days of online technical training, and a transparent thread rolling machine price without any hidden accessory fees.
Problems Encountered During Commissioning & Solutions
Challenge 1: The factory’s power supply had unstable voltage, leading to fluctuating hydraulic rolling pressure and uneven thread forming.
Solution: We sent matched voltage stabilizer accessories free of charge, stabilizing hydraulic power output and ensuring consistent rolling force.
Challenge 2: Local medium carbon steel contains minor impurities that scratched rolling wheel surfaces easily during continuous rolling.
Solution: Supplied customized high-hardness alloy rolling wheel coatings and guided workers to add full lubrication before each production shift.
Operation Improvements
- 150KN high stable rolling pressure eliminated shallow thread defects; reject rate dropped from 14% down to 0.7%, saving 2,400 MXN monthly on wasted steel blanks.
- Chipless cold rolling technology cut steel raw material waste from 13% to nearly zero, monthly material cost reduced by 7,200 MXN.
- 36–78 adjustable spindle speed lifted hourly output from 260 pieces to 510 pieces, production efficiency improved by 96%; large OEM order delivery cycle shortened by 8 days on average.
- Thickened standard rolling wheels extended service life from 10 days to over 90 days, monthly spare part expense cut by 1,620 MXN.
- ±5° adjustable spindle tilt angle guaranteed uniform thread pitch; all auto component batches fully passed OEM quality inspections, securing 3 long-term vehicle supply contracts.
Customer Feedback
“We compared multiple suppliers’ thread rolling machine prices and selected YG’s YG28-80 hydraulic thread rolling machine after checking full technical parameters. The 150KN rolling force perfectly handles our 42mm thick steel studs, solving our high reject rate and slow production troubles completely. Spanish remote technical support responds quickly whenever we have operation or die replacement questions. Higher daily output helped us deliver orders ahead of schedule and win more auto manufacturer cooperation. We plan to purchase one YG28-150 unit next quarter to expand our 48mm threaded rod production line.”
Case Study 2: Construction Rebar Processing Enterprise, Brisbane, Australia
Customer Background
A large construction material processing firm in Brisbane with 48 staff, specializing in rebar thread processing, rock anchor bolt and heavy foundation stud supply for highway, tunnel and high-rise building projects all over Queensland. The factory mainly processes thick steel bars 16–80mm for engineering connections, with a daily processing target of 9,000 rebar threads. Previously, they used two outdated low-pressure rolling machines unable to process 60–80mm thick rebar, losing many large infrastructure bidding projects.
Original Difficulties
- Old equipment maximum rolling pressure only 150KN, could not fully form deep threads on 65–80mm thick rebar; tensile strength failed Australian construction code standards.
- Narrow 110mm rolling wheel limited single processing length, requiring repeated rolling and cutting, wasting 3–4 hours daily extra labor.
- Low-power main motor caused frequent overheating during 10-hour continuous daily operation, with 2–3 unplanned shutdowns every workday.
- Fixed spindle center distance could not be adjusted for extra-thick bars, unable to meet the 70–80mm rebar project orders from local tunnel contractors.
- Slow after-sales spare parts delivery took over 25 days once rolling wheels broke, delaying the whole construction material supply chain.
Customized Solution
We supplied a YG28-200 heavy-duty rebar thread rolling machine tailored to their 14–80mm thick rebar processing demands. Key specs: max rolling pressure 200KN, processing range 14–80mm, 175–220mm rolling wheel, max wheel width 150mm, 11kw main motor, adjustable spindle center distance 150–300mm, total weight 2600kg. We provided English operation video tutorials, guaranteed spare parts delivery to the Australian warehouse within 10 days, and a clear thread rolling machine price including all standard rolling wheel sets.
Difficulties During Installation & Resolutions
Challenge 1: The factory workshop floor had uneven ground, causing machine vibration during heavy rebar rolling and slight thread pitch deviation.
Solution: Supplied thick steel leveling base plates free of charge to stabilize the whole machine and eliminate vibration.
Challenge 2: Local construction steel carries thick rust layers that accelerate rolling wheel abrasion during continuous mass production.
Solution: Taught workers pre-rust cleaning procedures before rolling and sent a full set of spare alloy rolling wheels as complimentary stock.
Project Benefits
- 200KN ultra-high rolling force produces standard deep threads on 80mm rebar, tensile strength fully meets Australian AS construction standards; the factory won 4 new tunnel project supply contracts after equipment upgrade.
- 150mm widened rolling wheel removes repeated rolling steps, daily extra rework labor time cut by 3.5 hours, monthly labor cost saved 5,800 AUD.
- 11kw high-power main motor eliminates overheating shutdowns; continuous daily production time extended from 7 hours to 10 hours, daily rebar output rose from 5,300 to 9,000 pieces (70% efficiency growth).
- Adjustable 150–300mm spindle center distance supports all 16–80mm rebar sizes, no need to switch separate machines for different bar diameters.
- Spare parts logistics only take 10 days, unplanned production downtime reduced by over 90%, material supply delays to construction sites eliminated.
