DIN-KO’s flow forming machines can be integrated with different production processes such as casting or forging, maintaining flexibility in production. The wheel mold design compatible with the machines becomes simpler, reducing costs by approximately 10-15%. 

DIN-KO has developed an innovative flow forming process called "hub forming" using flow forming machines paired with support rollers. This provides high efficiency for mass production of planetary gears and enables the manufacturing of high-precision gears, ensuring that gear dimensions and shapes meet strict specifications. The flow forming process produces gears as a single piece, which helps reduce manufacturing errors and allows the production of various types and sizes of gears. Due to its high production efficiency and relatively simple process, Ding Kang’s hub forming technology offers excellent cost-effectiveness for customers.

The C3 and C4 gear hubs are specific types of hubs designed for automotive applications, particularly within the transmission systems of vehicles. These hubs are integral to the smooth transfer of torque between components, ensuring precise engagement and disengagement of gears during shifts.

Both C3 and C4 gear hubs benefit from advanced manufacturing processes, such as DIN-KO’S precision machining or hub forming, which ensure tight tolerances and high efficiency in power transmission.
