Fly-free forging is the company's exclusive research and development of patented products, is the first in China to achieve mass factory, in line with the current automotive lightweight to reduce carbon emissions industry development trend. Although the product reduces the weight, it also increases the strength on the basis of the original.
At present, it has been put into the market for 5 years and has been well received by customers.

As an efficient and reliable metalworking process, closed forging is widely used in many fields because of its ability to produce complex parts with high strength and precision. With the continuous progress of technology, the closed forging process will be more widely used in the future, promoting the development of the manufacturing industry to a more efficient and higher quality direction.
Closed forging without flash
By cooperating with equipment manufacturers, we conducted research on the application of large-scale hydraulic presses in the forging industry, pioneered hydraulic flash-free hollow forging technology in China, and achieved leapfrog development in the lightweight design of commercial vehicle drive shaft assemblies.
Since it was put into operation in 2019, it has been verified by the market for 5 years and has been praised.
advantages of closed forging
1. High strength and durability: closed forging refines the internal grain structure of the metal through plastic deformation, eliminates the defects in the blank, and greatly improves the strength and durability of the forging.
2. High precision and complex shape: Due to the high precision of the mold, closed forging can produce parts with complex shapes and precise dimensions, reducing the subsequent processing amount and material waste.
3. High material utilization rate: compared with open forging, the material utilization rate of closed forging is higher, because it exerts a large pressure in the mold, and the volume of the metal blank changes little, thereby reducing the generation of flash and scrap.
What are the main product types of our company?
Advanced Connection Technologies: New types of spline connection and flange connection structures have been developed to improve the reliability of the connection and the transmission efficiency. For example, the involute spline connection has the advantages of large load-bearing capacity, high centering accuracy, and good guiding performance; in the optimized flange connection structure, by increasing the number of connecting bolts and improving the bolt arrangement method, the strength and stiffness of the connection are enhanced.
