As industrial manufacturing moves towards high-end, precision production, off-the-shelf equipment is no longer sufficient to cater for increasingly complex and diverse production scenarios. When faced with irregularly shaped workpieces, specialised materials or complex processes, standard hydraulic presses often fall short—moulds cannot be fitted, parameters do not match, and production ultimately has to be carried out as a ‘make-do’ solution. Shandong Zhongyou Heavy Industry Machinery Co., Ltd. fully understands this challenge. For the past 20 years since its establishment, the company has consistently prioritised ‘non-standard customisation’ as its core competence. By providing bespoke four-column hydraulic presses precisely tailored to the specific requirements of specialised processes—such as composite material forming and metal hot forging—it delivers reliable equipment support to cutting-edge sectors including aerospace, automotive lightweighting and rail transport.
Precise Adaptation to Composite Material Moulding Processes
The moulding of composite materials—particularly high-performance materials such as carbon fibre and glass fibre—places extremely high demands on equipment. Zhongyou Heavy Industry’s large-scale, non-standard servo four-column hydraulic presses have been specifically optimised to address the process characteristics of composite materials. The equipment utilises a fully closed-loop servo control system, enabling high-precision dynamic control of pressure, speed and position. The ram motion curve is flexibly programmable, supporting multi-stage speed and pressure settings, and is capable of precisely adapting to complex processes such as hot and cold pressing of SMC/BMC fibreglass and carbon fibre products.
In terms of temperature control, the equipment utilises an advanced multi-point closed-loop temperature control system, combined with highly uniform heating plates, to ensure an even temperature distribution across the working area, effectively preventing product deformation or poor bonding caused by uneven heating. With smooth pressure output and rapid response, it enables precise programming and displacement control during the pressurisation, pressure holding and depressurisation processes, ensuring that the material is subjected to uniform and consistent forces throughout the moulding process. This technical solution has been widely applied in cutting-edge fields such as aerospace composite moulding, the manufacture of lightweight automotive components, and structural components for rail transport.
Empowering Precision Machining in Metal Hot Forging
In the field of metal hot forging, the forming of complex forgings has always presented a core technical challenge—geometric features such as thin walls, deep cavities, asymmetry and multiple steps place almost exacting demands on the equipment. Zhongyou Heavy Industry’s large-scale, custom-built servo-driven four-column hydraulic press also demonstrates outstanding performance. The equipment utilises a high-strength, prestressed frame structure and a long-guide ram guidance system, ensuring excellent verticality and rigidity even under eccentric loads or asymmetric forging conditions. All welded components of the machine body are fabricated from high-quality steel plates and undergo comprehensive annealing treatment to eliminate internal stresses, enabling the equipment to maintain exceptionally high rigidity and stability when subjected to high-temperature, high-pressure impacts.
The combination of advanced hydraulic transmission and intelligent control systems enables precise closed-loop control of ram speed, pressure and position, endowing the equipment with exceptional process flexibility and allowing it to perfectly adapt to forging requirements for different materials and process curves. The equipment maintains stable operation even under demanding conditions such as high temperatures, heavy loads and continuous operation, providing reliable equipment support for the production of high-end components such as aircraft landing gear and engine turbine discs.
Intelligent Capabilities and Comprehensive Service Support
In terms of intelligent capabilities, Zhongyou Heavy Industry’s equipment deeply integrates the principles of Industry 4.0. Equipped with a large-format human-machine interface, process parameters can be easily set, stored and retrieved. Standard communication interfaces allow integration with factory MES/ERP systems, enabling equipment status monitoring, production data collection and remote management, thereby laying a solid foundation for the development of digital workshops.
From in-depth pre-sales research and solution validation, through rigorous quality control during the manufacturing process, to rapid post-sales response and preventive maintenance, Zhongyou Heavy Industry provides customers with service support covering the entire lifecycle of the equipment. With twenty years of technical expertise, Zhengxi Intelligent, guided by its mission to ‘manufacture intelligent equipment and liberate manual labour’, continues to provide safer, more stable, more efficient and smarter customised solutions for specialised process fields such as composite materials and hot forging.
