Coupling shafts with cold extruded process from cold extrusion supplier

The coupling is used for connection between electric machine and axle, or connection between engine and axle.

Cold extrusion features a massive forming process to produce both hollow and solid blanks in a multistage production process (multistage pressing).Presses with a very high closing force carry out cold forming of the material under a high pressure until the desired shape is achieved.

The material is extruded there by application of a high pressure. An upper die presses the blank through a forming and cross-section-reduced die orifice - the mold.

Longkou Dayuan, is able to make products with complicated geometry and a high forming degree.

Advantages of cold extrusion process:

1. high dimensional stability
2. excellent surface finish
3. continuous fiber flow line thanks to forming
4. efficient process for mass production
