We provide "convenience" to everyone through NC processing and general-purpose machinery, responding flexibly to needs.

Seki Manufacturing Co., Ltd. is a machining company with a long history that was founded during the Taisho era. Since its establishment, we have been involved in the processing of various products such as automotive parts, low-voltage parts, and connector parts, adapting to the needs of the times. We handle cutting processing of magnesium, aluminum, and zinc using machining and general-purpose machines, accommodating a wide variety of products, small and large lots, and short delivery times. We specialize in the insertion of helicoils (e-serts) and also accept orders for e-sert insertion only. Although we are a small team on-site, we can respond flexibly, so please feel free to contact us if you have any requests.
