Founded in 1941 in Niigata, Tsubame-Sanjō, Sōei Sangyō specializes in metal pressing processing for automotive parts in Asia and Indonesia.

Soei Sangyo Co., Ltd. was founded in 1941. Initially, it started as a manufacturer of aircraft sheet metal parts under the name Sanjo Aviation. After the war, it re-established itself as a factory for automobile parts manufacturing and actively expanded its business as a partner to automobile parts manufacturers from an early stage. Leveraging its capability for integrated production from mold design and manufacturing to pressing, welding, assembly, and painting, the company has achieved a track record in metal processing of all parts excluding the body for automobile components. With pride in being part of "Monozukuri Town, Tsubame-Sanjo," we will continue to focus on technological development that meets the times and aim to respond to the needs of customers not only in Japan but around the world. The first step in this direction is the "Indonesia Project."
