Company Information Image

Our precision metal parts processing technology is centered on the manufacturing of parts through cutting, a technique cultivated in the processing of watch components. In addition, we provide comprehensive part supply through secondary processing methods such as electrical discharge machining and grinding, as well as various surface treatments, heat treatments, assembly, and functional testing.

These technologies contribute to society in the brake parts field, which forms the heart of stability control and braking control units that are highly demanded for "safety" and "environmental" aspects in the automotive industry. Additionally, they play a role in the engine parts sector by contributing to fuel efficiency through solenoids in fuel supply systems.

Moving forward, we aim to become the best supplier capable of meeting the needs of a wide range of industries by continuing to focus on these core technologies and quality.
