Sekiguchi Sangyou Co., Ltd.

Our company manufactures shaft valves (power steering components), worm shafts, pinions, pistons, cored bars, and other engine and transmission parts that are mostly used in automobiles (for private and commercial use). We have established an integrated production system that can deal with all precision manufacturing processes from cold forging to machining with NC/MC lathes. We also process suspension parts, and stainless parts for medical uses. In our cold forging services we particularly excel at deep-hole boring up to 200 mm.
