Cost reduction case through cold forging: AT clutch piston
By converting the product that was drilled for 5 minutes into cold forging, the processing time has been reduced to 4 seconds, achieving cost reduction! Basic knowledge materials on cold forging are currently being offered!
We would like to introduce our examples of cold forging and shaping. The "piston for AT clutches" is a piston used to switch the clutch ON/OFF via hydraulic pressure. It is the spring seat required to release the piston when it is in the OFF position. Our spring seat shaping process involves arranging the press molds according to the number of spring seat holes and performing the shaping in one stroke with a single punch. 【Product Specifications】 ■ Material: SAE1020 steel plate (equivalent to S25C) ■ SIZE: Outer diameter Φ130 × L25mm *For more details, please refer to the PDF document or feel free to contact us.
