JHAO SIN was established in 1981. Its precursor was a Wei-Cheng hardware manufacturer. Founded by Mr. Chen, the factory specialized in manufacturing screws and rivets. At the beginning, it was a small factory. In order to promote the factory's productivity and serve customers better, we moved to this new factory with an area of 400 square meters. In the past 3 decades, JHAO SIN has stood firm in business with its sincerity, management ideas, and excellent manufacturing technology. Now, it is operated by the second generation of the family. Inheriting the management idea of the first generation, it continues to supply high quality products at reasonable price as its ultimate goal. Modern management skills are used, with the hopes of laying a new milestone in the business.
