4000 Ton CNC Tube Hydroforming Press
Automatic high-pressure hydraulic hydroforming equipment for the production of automotive components and other industrial metal tubular parts
These 4000-ton CNC tube hydroforming presses are used for manufacturing lightweight, high-strength tubular structural parts, mainly for automotive and industrial applications. Their design focuses on meeting current production demands for weight reduction, improved part quality, and higher efficiency. As tube hydroforming moves toward larger, more flexible, and more automated production lines, precise ultra-high-pressure control and servo-hydraulic systems play a key role in overall performance. The main features of CNC tube hydroforming presses include the following:
Energy Consumption
Servo motor drives are used across the CNC hydroforming press, resulting in lower power consumption and reduced operating noise
Cost Efficiency
Unmanned production with integrated processing steps improves material utilization and helps control overall production costs
Production Efficiency
The hydroforming press uses a dual-die setup, producing two parts per cycle to increase output efficiency
Intelligent Control
A servo control system based on the Beckhoff EtherCAT bus is used, providing fast communication and efficient data processing throughout the production process
Precision Control
A high-precision servo-hydraulic system is applied, with control accuracy maintained within ±0.1 mm to support stable and consistent forming results
