OUR STORY
Built by people who make things.
Founder Shih-Tung Shen at the first plant, 1990.
Lien Ya Machinery was established in Tainan in 1988. What began as a small workshop has grown into a manufacturing business focused on fasteners and custom metal components.
Hands-on experience remains at the center of our work. We combine cold forming, turning, threading and secondary machining to meet the needs of each part, with inspection integrated into the production route.
Our role starts before a machine runs: understanding the drawing, discussing manufacturability and agreeing what needs to be verified. It continues through production and delivery.
In-house operations are complemented by manufacturing partners where a project needs additional capacity or a specialist process. The production route and responsibilities are reviewed for each project.
Experience makes amazing.
