MCC Multi-directional Die Forging Line: A “Smart Factory” for Forgings

MCC Heavy Industry has built three multi-directional die forging production lines, creating a “smart factory” for producing complex forgings for high-end equipment. Through “intelligent linkage + precision control,” they have overcome the challenges of producing complex forgings. For example, the 40-meganewton multi-directional die forging line features a fully automated production process. A robotic arm precisely feeds metal billets heated to 1100°C into the die. Three sets of punches then apply pressure simultaneously from different directions, forcing the metal to flow along the die cavity, forming the complex forgings in a single step. This eliminates the multiple forging presses and subsequent processing required by traditional forging. The line’s intelligent monitoring system monitors forging parameters such as pressure, temperature, and time in real time, automatically adjusting any deviations from set values ​​to ensure dimensional accuracy within 0.2 mm. The system also records production data for each forging, enabling full traceability and facilitating subsequent quality inspections. Compared to conventional forgings, the forgings produced by this production line are flash-free and resemble finished parts, reducing subsequent processing time by 60%. They also feature finer metal grains, triple fatigue life, and over 20% improved mechanical properties. Currently, the production line supplies key forgings for wind turbine spindles and nuclear power pressure vessels for wind power, nuclear power, and aviation, driving the intelligent and domestically produced manufacturing of high-end forgings in my country.
