Prediction of the future development trend of forging process technology

The following is the forecast of the future development trend of forging process based on the analysis of industry technology evolution and market demand, covering process innovation, material application and intelligent upgrading:

1. Process integration: breakthrough in multi-station integration and labor-saving forming technology
The multi-station servo forging hydraulic press will accelerate the popularization and realize the one-time forging of long shaft and gear parts through the combination of forward/reverse/composite forging processes. This technology can increase material utilization to more than 95% while reducing the equipment footprint by 30%-50%.
The labor-saving forming process reduces the peak deformation force by 15%-204 by optimizing the stress state coefficient (K value) and flow stress (ReL value), combined with the split storage design (such as the gear precision forging annular blank scheme).

2. Material innovation: lightweight and domestic substitution of two-wheel drive
The transformation of forging raw materials to light alloys is accelerating, and the proportion of aluminum alloy and magnesium alloy forgings is expected to increase from 18% in 2022 to 35% in 2025. TC4 titanium alloy forgings have been mass-produced in scenarios such as battery brackets for new energy vehicles, with a density 60% lower than that of traditional steel, and a tensile strength of 900-1100MPa.
The localization rate of key forgings continues to rise, and more than 90% of core components such as engine crankshafts and steering knuckles have been supplied locally.

3. Intelligent upgrading: deep penetration of digital twins and flexible production lines
The digital design system based on CAD 3D modeling and finite element simulation can shorten the forging process development cycle by more than 40%, and at the same time realize the forging tolerance control within ±0.2mm.
The flexible forging production line supports small-batch and multi-variety production through modular mold combination and intelligent temperature control system, and the time to switch product models is compressed to 15 minutes.

Fourth, precision development: net shape forging and energy consumption optimization
The breakthrough in net forging technology has made the proportion of forgings close to net shape reach 70%, and the machining allowance has been reduced from 2-3mm in the traditional process to 0.1-0.5mm, significantly reducing the subsequent machining cost.
The hot and cold forging composite process combined with liquid die forging technology can reduce the energy consumption per unit of forging by 28%-35%, and the average energy consumption of the industry is expected to drop to 1.2 tons of standard coal per ton of forgings in 2025.

5. Industry Ecology: Vertical Integration and Global Layout
Leading enterprises have accelerated the construction of an integrated industrial chain of "smelting-forging-finishing", and aluminum giants such as Weiqiao Group have reduced the cost of forged aluminum parts by 18% through the direct supply mode of molten aluminum.
Overseas production capacity expansion has accelerated, and domestic forging companies have built more than 20 intelligent production lines in North America and Southeast Asia, focusing on covering the new energy vehicle chassis and power system forging market.

Conclusion: The forging process is iterating in the direction of "high efficiency-precision-low carbon", and process integration innovation (such as multi-station servo forging), lightweight material application (titanium/aluminum/magnesium alloy) and digital penetration improvement (digital twin flexible production line) will become the three core growth poles. It is estimated that by 2028, the scale of the global forging industry will exceed 280 billion US dollars, of which new energy vehicle forgings account for more than 40%.
