In 1996, Ningbo Yinzhou Chengyuan Electronic Components Factory was officially established in Jialin Village, Yunlong Town, Yinzhou District, focusing on the production and manufacturing of relays and electronic components. At the beginning of the factory's establishment, the enterprise firmly established the business philosophy of "honesty as the foundation and quality as the soul", and through exploration, accumulated valuable production experience, laying the foundation for subsequent development. 

Entering the new century, the enterprise completed the transformation from a start-up to professional production. It mastered mature processes in areas such as relays and hardware accessories. By forming an efficient and collaborative technical team, the quality of products steadily improved, and it began to build a reputation within the industry.
