Features

High Output
20–45 pcs/min (size-dependent)

Precision
±0.05 mm positioning accuracy ensures perfect die alignment-reduces forging defects and extends tool life.

Fast Changeover
Quick-change tooling and digital presets allow switching between sizes (e.g., M20 → M36) in under 10 minutes.

After-Sales Service

On-Site Commissioning: Engineers install, calibrate servo parameters, synchronize heating cycles, and validate final part quality.

Operator Training: Hands-on programs for HMI operation, quick-change procedures, and preventive maintenance.

24/7 Remote Diagnostics: Secure remote access for instant troubleshooting-minimizes downtime without travel delays.

Spare Parts Guarantee: Critical components (servo drivers, grippers, sensors) stocked globally-dispatched within 48 hours.

Warranty: 12-month full coverage on core mechanical and electrical systems; extended service contracts available.

FAQ

What is the specific size range for this nut former?
This series is optimized for M12 to M48 nuts, handling clamp diameters from 12mm to 48mm and billet lengths up to 150mm, covering the highest volume market segment for hex and flange nuts.

How quickly can we change over to a different nut size?
Using digital servo presets, the machine automatically adjusts stroke and timing. Combined with modular grippers, a full changeover (e.g., M20 to M24) takes under 90 minutes, allowing efficient mixed-batch production.

Can this integrate with our existing induction heater?
Yes, if your heater supports external PLC signaling. However, our integrated turnkey package (Heater + Former + Press) is recommended to guarantee perfect synchronization and achieve the claimed 30% energy savings.

Does the system support Industry 4.0 data collection?
Yes. Our PLC includes native Ethernet/IP and Modbus TCP ports, enabling seamless connection to MES/ERP systems for real-time monitoring of output, downtime, and energy usage.

How does the equipment handle the extreme heat of the billets?
The manipulator arms are constructed with heat-resistant alloys and feature active cooling systems for critical components, ensuring stable operation in environments exceeding 1000°C without degradation in precision.
