What are the main product types of our company?

Precision Manufacturing Processes: Advanced processes such as cold extrusion and precision forging are applied to improve the manufacturing accuracy and surface quality of the drive shaft. The cold extrusion process can make the material fiber flow lines continuous, improving the strength and toughness of the parts; precision forging can precisely control the size and shape of the parts, reducing subsequent machining allowances and improving production efficiency.

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.

Where are the main technologies of the drive shafts of our company?

• Heavy - duty drive shaft: Widely used in commercial vehicles, construction machinery and other fields, it is of vital importance to the safety performance of the main engine and is one of the company's main products.
