King Slide, a Taiwanese maker of kitchen drawer slides, controls 70-90% of the high-end AI server rail market and on Oct 30 approved over $600M for what it plans as the world's largest rail factory.
- Server rails work like drawer slides: three steel strips on steel balls, 6.1mm thick, holding 40kg+ chassis with 100+ parts per rail at 0.02mm tolerances
- Moat: you can buy the steel and balls, but must build your own molds, stamping/plating lines and assembly machines, plus design around 3,750 patents
- Nvidia's next racks are heavier while rails must get thinner to make room for liquid-cooling pipes
