TYC (Tien Yuen Machinery Mfg. Co. Ltd.) was established 60 years ago, from the former "Tong-Yan Iron Works Kabushiki Kaisha" in the Japanese-Occupation period.

After Restoration of Taiwan in 1945, the government took over the company and made it private. At beginning the company was producing steel spades and steel barrels.

In 1955 the company was reorganized and became Tien Yuen Machinery Mfg. Co. Ltd. A whole set of chain production machines was imported from Germany and the company started the production of bicycle chains.

TYC concentrates on manufacturing and developing industrial chains for power transmission and conveyance. We continuously dedicate ourselves to new product development, quality improvement, technology advancement and efficiency enhancement. Through years of hard work the company has grown and become the largest industrial chain maker in Taiwan with complete product lines.
