YANGLI Group Celebrates the Official Launch of the 3,750T Ultra-Large Intelligent Multi-Station Press Line

A Milestone in Metal Forming

YANGLI Group is proud to announce the successful launch of the TL4-3750T ultra-large offset-resistant multi-link multi-station press line —the latest generation of independently developed intelligent stamping equipment. With a press capacity of 3,750 tons, this system represents the largest-tonnage multi-station press line in China and sets a new benchmark for the domestic metal forming industry.

Overview of the Production Line

The TL4-3750T is a fully automated, intelligent stamping solution designed for high-efficiency, flexible production of medium-to-large parts. The complete line integrates the following advanced systems:

• Dual-station automatic blank de-stacking system – ensures continuous material supply with minimal downtime
• 37,500 kN multi-link multi-station press – the core unit, offering outstanding offset resistance and precision
• Servo three-dimensional multi-station transfer system – enables precise and fast part handling between stations
• Automatic quick die change system – drastically reduces setup time for different part runs
• Automatic end-of-line belt conveying system – ensures smooth and efficient part output
• Intelligent visual recognition and tracking system – monitors part quality and position in real time
• Adaptive servo control system – dynamically adjusts parameters for optimal performance

Key Advantages

🏆 Unmatched Tonnage and Capacity

As the largest single-unit multi-station press line in China, the TL4-3750T offers exceptional capacity for processing large and complex workpieces. Its extra-large worktable easily accommodates a wide variety of part sizes and geometries.

🎯 Superior Offset Resistance

The press is engineered with a high-strength offset-resistant structure, allowing it to handle asymmetric loads with stability and precision—a critical capability for complex stamping operations.

🌍 World-Class Accuracy

The entire line is built to the highest international standards, delivering precision and repeatability that meet the most demanding manufacturing requirements.

⚡ Fully Automatic and Intelligent

With integrated automation and adaptive controls, the TL4-3750T supports fully automatic, intelligent flexible stamping, minimizing manual intervention while maximizing productivity and quality consistency.

From Contract to Reality

In April 2025, YANGLI Group formally signed the “3,750T Intelligent Multi-Station Press Line” project with Harbin Institute of Technology Yongxing (哈工永兴) at an industry exhibition in Beijing.

Just one year later, the production line has been successfully completed and officially launched—a testament to YANGLI’s engineering excellence and project execution capability.

The Spirit of YANGLI Manufacturing

This achievement reflects the core values that drive YANGLI:

“Striving for excellence, pursuing perfection”

Through relentless innovation and dedication, YANGLI has overcome a series of core technical challenges to bring this project to life. The successful launch of the TL4-3750T exemplifies the strength of “YANGLI Intelligent Manufacturing” —a commitment to delivering world-class solutions that compete on the global stage.
