AI infrastructure
Manufacturing for the AI Infrastructure Era
As compute grows, two physical limits appear: how AI hardware is made, and how its heat is removed. Both come down to machining the hardest materials precisely.
- 01
AI Hardware Manufacturing
Precision machining for:
- Advanced ceramics
- SiC
- Diamond-related materials
- Precision thermal components
- 02
Thermal Management Manufacturing
Precision shaping of:
- Hard and brittle thermal substrates
- Micro-channel structures
- Diamond-related thermal materials
As AI pushes compute higher, Leidao drives manufacturing cost lower.
