Product Performance Characteristics
Stable Mechanical Properties
It can improve internal structural defects such as porosity, enhance material density and uniformity, and help optimize mechanical properties including tensile strength, toughness, hardness and fatigue strength.
Controllable Dimensional Accuracy
With reasonable forming allowance, it can reduce subsequent machining workload and improve material utilization efficiency.
Good Material Utilization
The forming contour of the forging process is close to the finished shape, which can reduce material loss compared with traditional processes such as casting.
Reliable Service Performance
Under repeated loads and complex working conditions, the service life of forged lifting lugs is usually longer than that of castings or ordinary machined parts.
Strong Customization Adaptability
Products meeting specific performance and structural requirements can be produced by adjusting tooling and process parameters.
Controllable Machining Cost
Forged products usually only require a small amount of subsequent machining, such as cutting and drilling, which helps save machining time and comprehensive costs.
Core Technical Parameters
