Lin Tsung-chih, the 85-year-old founder of Taiwanese company King Slide Works, just took the top spot as Taiwan's richest person thanks to a massive spike in demand for AI server components. According to the WSJ, King Slide’s stock has surged nearly 280% since the start of the year.

From Cabinet Hinges to Server Rails

King Slide made its name producing cabinet hinges and drawer slides, but it also manufactures rail systems for server racks. These rails support heavy-duty computing gear and let technicians slide equipment out for maintenance without messing up airflow or cooling.

Market Share and Stock Surge

The WSJ estimates King Slide controls about 80% of the global market for rails used in high-performance servers. The explosion in AI infrastructure has fueled demand for these parts, propelling Lin Tsung-chih to the top of Taiwan’s rich list.

Why Server Rails Matter for AI

Server rack rails are a critical piece of data center hardware—they allow easy access to servers for upgrades or repairs without disrupting cooling systems. As AI workloads ramp up and data centers expand, demand for reliable rails has shot up, boosting King Slide’s market position and stock price, as highlighted by the WSJ.
