Manufacturing diesel injection pump parts, precision parts, and molds with short delivery times and low costs!

At Sankyo Co., Ltd., we provide diesel injection pump parts, precision parts, and molds through a series of cold forging and machining processes. We have established a comprehensive production system that covers everything from mold and jig manufacturing to cold forging, heat treatment, bonding processing, and machining. In the future, we will focus particularly on reducing machining and achieving non-machining by leveraging cold forging, and we aim to continue meeting the demand for "good products, at low cost, and quickly."
