The steering ball joint blank is used for automobile steering and suspension system. It is made by high quality carbon steel (material S45C), through cold forging(cold extrusion) processes, we can supply blank and finished product.
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:
· high dimensional stability
· excellent surface finish
· continuous fiber flow line thanks to forming
· efficient process for mass production
