Automatic Thread Rolling Machine: 4 Core Application Scenarios
Construction Engineering
Rebar connection processing in high-rises and residential projects, one-time forming without open flame.
Practical tip: Pair with rebar couplers for joint strength 20% higher than base metal.
Bridge & Tunnel Projects
Process large-diameter rebar (32-40mm), cold rolling boosts thread fatigue strength by 60%.
Practical tip: Activate the built-in cooling system to avoid precision loss from high temperatures.
Industrial Manufacturing
Produce mechanical parts and fasteners, supporting HRB335/HRB400 rebar with 6H thread precision.
Practical tip: Choose a hydraulic thread rolling machine for high-strength metal processing.
Prefabricated Component Factories
Bulk rebar processing for precast beams/walls, automatic feeding reduces manual intervention.
Practical tip: Enable auto-counting to simplify production capacity tracking.
YG Automatic Thread Rolling Machine: 4 Core Advantages

High Efficiency & Automation, Save Labour Costs
Integrated auto-feeding, rib stripping, and threading—operated by one person, 5x faster than manual.
Practical tip: Add an auto-loading rack for 24-hour continuous processing.
High Precision, Reliable Joint Quality
Thread precision error ≤0.05mm, consistent diameter, meeting US/EU construction standards.
Practical tip: Check rolling die wear regularly to maintain stable precision.
Durable Structure, 8+ Year Service Life
4kw motor-driven, high manganese steel body, 8-hour daily trouble-free operation.
Practical tip: Clean the cooling system monthly to extend core component life.
Flexible Adaptation, Multi-Spec Processing
Supports 16-40mm rebar, max processing length 80mm (custom 25cm extended version available).
Practical tip: Replace rolling dies to switch between rebar diameters quickly.
Success Stories: Efficiency Boost from US & Germany Clients

US: Mike’s Construction Project Cuts 40% Time
Mike, a Texas contractor, faced two issues with manual machines:
- 3 workers operated one machine, only 8pcs/hour, failing to meet deadlines;
- Unstable thread precision, 85% joint pass rate, frequent rework.
He chose YG’s automatic thread rolling machine with auto-feeding:
- 1 worker achieves 35pcs/hour, labour costs reduced by 67%;
- 99.8% thread pass rate, zero rework, project finished 20 days early.“This machine makes us stand out,” Mike said. “We use it for every project now.”
Germany: Thomas’s Prefab Factory Doubles Capacity
Thomas ran a precast factory, needing bulk processing of 32mm large-diameter rebar.
His old machine took 3 minutes per piece, with poor cooling causing thread deformation.
After adopting YG’s automatic thread rolling machine:
- Processing time down to 90 seconds per piece, daily capacity from 120 to 280pcs;
- Built-in cooling system controls temperature, thread deformation ≤0.03mm.“We found YG via a thread rolling machine for sale,” Thomas shared. “It meets EU standards perfectly.”
