About Us

Sunyi Precision Engineering

Sunyi Precision Engineering was established in 1989 as a machine shop providing conventional turning services for the electronics industry in Singapore.

Fueled by growing demands for a wider range of services and a continuous increase in turnover, Sunyi Precision Engineering was privatized in 1995 to incorporate additional capital for the expansion of machining and quality assurance capabilities.

Through the constant upgrading of our manufacturing capabilities and our organizational culture for process efficiency and continuous improvement, Sunyi Precision Engineering is a reputable company in Singapore today for the provision of high-mix low-volume precision machining services.
