FAQ

What is the specific size range for this automatic equipment?
This model series is optimized for M12 to M48 fasteners. It handles clamp diameters from 12mm to 48mm and billet lengths up to 150mm, covering the highest volume segment of the fastener market.

How does the changeover process work for different sizes?
The system uses digital servo presets. Operators select the product recipe on the HMI, and the machine automatically adjusts stroke length, grip width, and timing. Mechanical gripper changes take less than 90 minutes total.

Can this equipment integrate with our existing induction heater?
Yes, provided the heater supports external PLC signaling. However, we recommend our integrated turnkey package (Heater + Manipulator + Press) to guarantee perfect synchronization and maximize the 30% energy saving claim.

Does the system support data collection for Industry 4.0?
Absolutely. Our PLC system includes native Ethernet/IP and Modbus TCP ports, allowing seamless connection to your factory's MES or ERP system for real-time monitoring of output, downtime, and energy usage.

What kind of maintenance is required?
Daily checks involve lubrication of linear guides and inspection of gripper pads. The servo system is maintenance-free for over 20,000 operating hours. We provide a detailed preventive maintenance schedule upon delivery.
