The Inner Ball Joint (IBJ) Housing is a safety-critical component of the axial joint that transmits steering loads through the tie rod and the outer joint to the front wheels. It is a cold extrusion product. Material is S25C. It is an automotive steering link part. The products we are producing which diameter are ∮35, ∮38 and ∮41.

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
