Information for Buyers
China cold forging brake piston which cold extrusion parts manufacturer and supplier
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
