Product Description

The piston is used for automobile braking and chassis system, Through cold forging cold extrusion process, machining, E-plating, accurate grinding, polishing etc. to be a finished product, the piston is made by high quality carbon steel material S10C and S20C . We currently produce piston which diameter from ∮34 to ∮75. We are supplying it for Korean Sang-Shin Brake,etc.

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
