Production Capacity & Dimensional Range
Heavy Industrial Range: Processes M12 to M48 standard and high-tensile nuts (19 mm–75 mm AF across flats).
High-Volume Output: Reaches 20 to 45 pcs/min depending on workpiece mass, metal displacement, and station count.
Extended Forming Stroke: 170 mm to 300 mm stroke lengths enable deep-cavity forming and reliable part clearance.
Precision Thickness Tuning: The 0–20 mm height-adjustment mechanism allows rapid adjustment for varying blank sizes with ±0.05 mm repeatability.
Forming Capability
Heavy Structural Hex Nuts: High-speed cold/warm forming for DIN 934 and ASTM A194 heavy hex profiles with precise face geometry.
Flange & Wheel Fasteners: 3-station and 4-station sequences form integral washers and wheel nuts in a single pass without secondary machining.
Specialty Geometries: Produces asymmetrical structural nuts, threaded collars, and custom locknuts with zero material scrap loss.
Progressive Multi-Station Forming: 3 and 4-stage transfer options distribute forging tonnage evenly to minimize stress concentration and double die life.
Near-Net-Shape Accuracy: Holds tight dimensional tolerances, eliminating finish-grinding steps for high-volume fasteners.
Typical Applications
Automotive Fasteners
Forges suspension-grade high-tensile nuts to ISO 898-2 Classes 10 and 12 specifications.
Heavy Infrastructure
Forms structural tie-rod nuts and heavy anchor fasteners for bridges, mining equipment, and wind towers.
Energy Sector Fasteners
Produces hot-dip-galvanizing-ready nuts for extreme corrosion resistance and fatigue performance.
Custom Line Engineering
Custom-engineered automation platforms integrate seamlessly with client presses ranging from 125T to 3000T.

Installation & After-Sales Support
On-Site Integration: Field service engineers handle mechanical installation, sensor calibration, and production line integration at your facility.
Operator Certification: On-site technical training covers PLC troubleshooting, die setup, and preventive maintenance procedures.
Guaranteed Spare Parts: Stocked wear components and servo drives are dispatched within 48 hours.
FAQ
Q: What is the average service life of the forming dies used in this machine?
A: Under standard operating conditions with alloy tool steel dies, service life ranges between 80,000 and 120,000 strokes before die replacement is needed.
Q: What is the typical lead time for a custom nut former line?
A: Standard configurations ship within 45-60 days after order confirmation, while fully customized multi-station lines require 75-90 days.
Q: Do you provide any quality certifications for your machines?
A: Yes, all machines are manufactured under ISO 9001:2015 quality management systems and carry CE certification for export to the EU market.
Q: What warranty period is offered on the main press and control system?
A: We provide a 12-month warranty on the mechanical press structure and a 12-month warranty on the PLC control system, covering parts and technical support.
Q: Is there a minimum order quantity for spare parts or accessories?
A: No minimum order quantity applies to spare parts; single-unit orders for wear components like dies and knockout pins are accepted.
Q: What is the typical energy consumption of a mid-range nut former line?
A: A standard 4-station line rated for M20-M30 nuts consumes approximately 45-60 kW/h during full production, depending on stroke rate and workpiece mass.
