Dalian Tienyuen Industrial Co., Ltd. was established in 1998 by Taiwan’s TYC Group, which was founded in 1955 and has over seven decades of experience in manufacturing precision transmission roller chains. Renowned for its reputation and quality, TYC Group is a leading Taiwanese manufacturer of precision transmission chains. The company boasts a strong R&D team, advanced mold-making equipment, and several chain-production technologies that rank among the world’s best. It can produce more than 400 chain specifications conforming to both U.S. and European standards, with nearly 4,000 different product combinations including chains and accessories. The breaking strength and fatigue strength of its products both exceed international standards by more than 20%. Currently, the company operates a main plant in Dalian, a factory in Taiwan, and a plant in Thailand.

Dalian Tienyuen Industrial Co., Ltd. was established in 1998. Over 80% of the company’s main chain products are exported overseas, serving markets in Europe, the United States, Japan, Southeast Asia, and other regions. More than 98% of the company’s equipment is either imported or custom-made in-house. The design and production of molds are both supported by the parent company, ensuring that mold processing meets precision standards. High-precision production equipment, heat treatment facilities, and processes rigorously guarantee the stability and consistency of key component performance. Paired with the company’s own high-performance assembly machines, these chains exhibit exceptional structural integrity and significantly enhance overall chain quality and performance. Through specially developed process settings, we can meet customers’ specific requirements, such as high tensile strength, excellent fatigue resistance, and superior wear resistance. We are also capable of designing and manufacturing non-standard chains with various pitch sizes, materials, and accessories featuring specialized functions.

The application equipment and types include printing machinery, petroleum machinery, food machinery, construction machinery, packaging equipment, paper-making equipment, medical devices, three-dimensional parking equipment, conveying equipment, coating and tinplate canning equipment, automotive and motorcycle engines, chain drives for high-speed racing cars, pallet chains for forklifts, glass conveyor chains, elevator and escalator chains, as well as chains used in reservoirs and wastewater treatment systems.

The company has established a comprehensive quality management system, equipped with fully stocked inspection and testing facilities, and has obtained ISO9001:2015 certification for its quality management system. It has been rated as an A-class enterprise by the customs authorities and, following a successful assessment in 2003, was designated as an export-exemption enterprise by the Commodity Inspection Bureau. In 2007, it was recognized as a high-tech enterprise.
