Fast Size Changeover
Modular tooling and quick-clamp dies enable switching between sizes (e.g., M8 to M12) in under 20 minutes.

After-Sales Service

Installation & Training: On-site commissioning and hands-on operator training included. Remote support available anytime.

Warranty: 2-year warranty on mechanical and electrical core systems (servo motors, PLC, main drive).

Remote Diagnostics: Secure IoT connection allows our engineers to monitor performance, adjust parameters, and troubleshoot in real time.

Preventive Maintenance Plans: Optional annual service contracts include alignment checks, lubrication system audit, and performance optimization reports.

FAQ

What is the maximum diameter your machine line can handle?
Our standard lineup covers 55mm to 100mm max clamp diameter. The 160K/200K models handle up to 60mm, the 250K/315K up to 85mm, and the 400K series handles up to 100mm. Custom solutions for larger diameters are available upon request.

How fast can we switch between different nut sizes?
Thanks to the servo-driven adjustments and modular tooling, a standard size changeover (e.g., M60 to M70) can be completed in under 2 hours, minimizing downtime for multi-spec production runs.

Does the price include the heating furnace and press?
We offer both standalone manipulator units and complete turnkey lines. The full package includes the automatic feeder, induction heating furnace, manipulator, and hydraulic press, all synchronized via a central PLC.

What is the power consumption for the servo system?
Servo motor power ranges from 3kW to 4.5kW depending on the model (e.g., 3kW for 160K, 4.5kW for 400K). The total line energy saving comes primarily from the high-efficiency induction heating system, which reduces overall energy costs by 30–40% compared to traditional methods.

Can the system integrate with our existing ERP software?
Yes. Our control system supports standard communication protocols (e.g., OPC UA, Modbus) to exchange real-time data on production counts, fault logs, and inventory status with major ERP platforms.
