Forging Force & Machine Performance
Forging Capacity: Delivers 35–45 strokes/min on 160-ton models and 20–30 strokes/min on heavy-duty 400-ton lines.
Thermal Protection: Water-cooled grippers and thermal barriers protect pneumatic and electronic sensors in forging environments exceeding 1000°C.
Continuous Stability: The heavy-duty cast-iron body dampens vibrations from continuous forging, maintaining precise alignment under maximum load.
Multi-Station Forming Configuration
Multi-Stage Transfers: Configurable for 3-station and 4-station sequences: Descaling/Upsetting → Forming/Hexing → Piercing/Punching.
Dynamic Clearance: Motorized beam lift ("G" series) offers 0–120 mm clearance for complex lower dies and raised ejector pins.
Tooling Stroke: Integrated 0–20 mm bolster adjustment accommodates thick custom die blocks without shimming.
Quick-Release Grippers: Mechanical quick-change gripper arms enable complete die set changes in under 30 minutes.


Customization Options
Geometry Tailoring: Custom station layouts engineered for specific cross-flat dimensions, flange diameters, and non-standard nut profiles.
Material: Machine power and induction heating systems configured for specific alloy grades, stainless steels, and billet sizes.
Process Flow Sequence: Custom station mapping for unique combinations of upsetting, piercing, expanding, and sizing.
Plant & Automation Integration: Customized machine footprint, material feed direction, utility connections, auto-feeders, billet elevators, and robotic bin-picking systems.
Quality Control
Transfer Repeatability: Servo-driven transfers hold multi-station positioning tolerances within ±0.15 mm across all passes.
Die Protection Interlocks: Thermal sensors and double-blank detectors stop the press instantly upon misfeed to prevent die crashes.
Standard Compliance: Maintains wall thickness and concentricity to meet ISO 4759-1 and DIN 934 fastener specifications.
In-Line Force Monitoring: Real-time tonnage sensors track forging load per station to detect worn tooling before defects occur.
Delivery Terms
Lead Time: Standard configurations ship in 80–120 calendar days following a mandatory 72-hour pre-shipment dry run.
Tooling Package: Includes Cr-Mo-V alloy initial dies and a 12-month wearable spares kit (grippers, punches, push rods).
Export Packaging: Sealed in VCI anti-rust film and packed in sea-worthy steel-framed wooden crates with full CE/ISO compliance files.
Commissioning & Support: Covers 10 days of on-site installation and operator training, backed by a 48-hour global field service response.
FAQ
Q: What warranty period applies to the main press frame and servo transfer system, separate from the wearable spares kit?
A: The main press body and servo-driven transfer system carry a 24-month structural warranty, distinct from the 12-month wearable spares package already included.
Q: What is the typical service life of the cast-iron press body before major overhaul is needed?
A: Under normal three-shift operation, the cast-iron body and main bearings typically run 12-15 years before requiring a major structural overhaul.
Q: Do you offer factory acceptance testing (FAT) before shipment?
A: Yes, we conduct FAT with live video streaming for overseas buyers who cannot travel, in addition to the standard 72-hour pre-shipment dry run already performed on-site.
Q: What payment terms are typically offered for a full nut former line?
A: Standard terms are 30% deposit, 60% before shipment, and 10% after commissioning acceptance, with T/T or L/C accepted.
Q: What is the average electricity consumption for a 400-ton heavy-duty line during full production?
A: A 400-ton configuration typically draws 75-90 kW/h under continuous multi-station operation, depending on billet size and stroke rate.
