DAYI Empowers Guangda-8,000Ton Forging Press Enters Production

Recently, the YD13F-8000-ton frame-type free-forging hydraulic press supplied by Dayi Heavy Forging Technology Co., Ltd. to Zhangjiagang Guangda Special Materials Co., Ltd. (Stock Code: 688186),has successfully completed its installation and commissioning phases and has officially entered production. With a rated pressure of 80,000 kN and an annual designed capacity of 60,000 tons, this equipment serves as a core asset for Guangda Special Materials in its efforts to optimize its special materials forging value chain and enhance its manufacturing capabilities for large-scale precision forgings. Leveraging its leading-edge technology and comprehensive end-to-end services, Dayi Heavy Forging has provided robust support for its client's strategic upgrading initiatives.

Project Background: Meeting the End-to-End Demand—From Material Smelting to Precision Forging

As a leading enterprise in China's high-end specialty materials sector, Guangda Special Materials specializes in the production of high-temperature alloys, titanium alloys, nickel-based alloys, and special steels. Its products are widely utilized in high-end equipment manufacturing fields such as wind power, aerospace, nuclear power, and rail transit. To further integrate the entire industrial chain—spanning both "material smelting" and "precision forging", Guangda Special Materials sought to acquire a large-tonnage, high-precision, and multi-functional free-forging hydraulic press to enable the independent and controllable production of large-scale forgings.

After comprehensively evaluating numerous domestic and international equipment suppliers, Guangda Special Materials ultimately selected DAYI as its partner. DAYI earned the client's complete trust by leveraging its extensive technical expertise accumulated over years in the heavy-duty hydraulic press sector, its mature design experience regarding frame-type forging presses, and its comprehensive after-sales service system.

DAYI Solution: 8,000-Ton Frame-Type Free Forging Hydraulic Press

1.Key Equipment Parameters

2. Technical Advantages

l High-rigidity frame structure: The entire machine adopts a pre-stressed frame design, offering excellent rigidity and strong resistance to eccentric loads, meeting high-precision forging requirements for large, complex-shaped forgings.

l Advanced hydraulic control system: Uses cartridge integrated valve blocks and large-flow high-speed forging integrated control, with step pressure regulation, fast pressure build-up and release, high forging frequency, and low impact.

l Four-corner, eight-face rail guidance: The slider is guided with high adjustment accuracy and smooth operation, effectively ensuring dimensional consistency of forgings.

l Intelligent control system: Supporting fully automatic forging cycles, real-time data monitoring, and storage/recall of process parameters.

l Reliable cooling and filtration system: Ensures thermal stability and cleanliness during long hours of continuous operation.

3. Delivery and Installation Services

DAYI provided full-process services from equipment design, manufacturing, transportation, installation and commissioning, to personnel training. Considering the site conditions at Guangda’s factory, we optimized the foundation design and equipment layout to ensure the fastest possible installation and trial production. Our project team stayed on site to assist the customer with the trial production of the first batch of high-temperature alloy forgings, achieving a 100% first-pass acceptance rate.

Customer Value: Forging Capability Leap and Enhanced Market Competitiveness

After commissioning, Guangda Special Materials has realized the following core values:

l Capacity increase: Annual output of 60,000 tons of large free forgings, enabling mass supply of high-end forgings such as wind power main shafts, gearbox structural parts, aero-engine disks, and nuclear flanges.

l Full process coverage: A single machine can perform multiple complex forging processes, reducing outsourcing dependence and shortening production cycles.

l Improved material utilization: High-precision forging control reduces machining allowances, lowering subsequent machining costs.

l Access to high-end markets: Capable of producing aerospace-grade titanium and high-temperature alloy forgings, expanding into higher value-added markets.

Cooperation Outlook: Continuous Empowerment, Building the Future of High-End Manufacturing Together

The successful commissioning of Guangda Special Materials’ 8,000-ton free forging hydraulic press is another benchmark case for DAYI in the field of large free forging hydraulic presses. As a long-term trusted partner, DAYI will continue to provide comprehensive support including equipment maintenance, spare parts supply, and process optimization.

Moving forward, DAYI Heavy Forging Technology Co., Ltd. remains committed to the R&D and innovation of metal forming equipment, delivering more efficient, intelligent, and reliable forging solutions to customers worldwide, and supporting the high-quality development of high-end manufacturing.
