[Press Processing Example] Automotive / Precision Fitting Parts (4×12)

Manufacturing technology for precision fitting parts consisting of 4 types and 12 components! Proven track record of delivery to major automotive parts manufacturers!

This is a complex shaped stamping product used for male-female fitting. To ensure that customers can assemble it smoothly and that it does not leak during use, optimal clearance is required, achieving a face clearance of 0.16 mm during fitting. It balances leak prevention with workability during fitting and has been adopted by major Tier 1 companies. The outer part is made of stainless steel with significant springback, requiring contour accuracy in the hundredths for both male and female components, which we address with our unique press forming technology developed over many years in fuel supply unit processing. This product also accommodates barrelling processing, which is said to be very difficult due to the tight bending edge. The inner part is processed in a progressive manner with groove and drawn shapes, and we conduct precision management of individual parts to ensure that five stacked sets can fit together with the outer part at the required precision.
