Megawatt CDU Manifold Machining
CNC machining support for high-flow CDU manifold blocks where pressure integrity and distribution geometry affect deployment-critical uptime.
Core bottleneck: Megawatt-class liquid cooling rollouts require manifold capacity and precision faster than many standard supply channels can provide.
Manufacturable Scope
- Large-block manifold cavity and deep-feature machining
- Flow-path tolerance governance for distribution consistency
- Pilot-first execution for schedule-critical AI cooling projects
Representative Part Scope
- CDU supply/return distribution blocks
- High-flow branch manifold structures
- Sealing-face interfaces for modular assembly
- Inspection-ready tap and port geometry features
Proof Checkpoints
- Pressure-hold or leak test method can be configured per customer validation standard
- CMM checkpoints on branch spacing, port location, and sealing datums
- Visual and dimensional verification records released with each lot
Materials & Process Focus
- High-flow path machining stability on large blocks
- Port-to-port positional consistency across batches
- Interface flatness and sealing reliability under service pressure
Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Pressure integrity verification | RFQ-defined pressure-hold or leak test sequence | Large manifold leakage can create deployment delays and costly rework. |
| Critical port-position control | CMM-verified branch and interface coordinates | Port drift causes installation friction and unpredictable flow distribution. |
Risk Controls
- Flow-performance assumptions exceed part-level scope: Limit claims to machined geometry and validated inspection results; whole-loop CFD outcomes remain system integrator scope.
- Late interface conflicts at install stage: Lock mating standards and gasket stack details before prototype release.
Buyer FAQ
Can you certify full CDU system flow performance?
We verify machined geometry and agreed integrity tests. Full system flow behavior depends on pump, piping, and controls outside machining scope.
What is the fastest path for a first manifold sample?
Submit CAD with pressure/test criteria and interface standards so DFM closure and pilot scheduling can start immediately.

Upload CAD and drawings for a one-business-day first response when the RFQ package is complete. We review manufacturing risk before quote direction and partner-route planning, rather than issuing blind automated pricing.
Typical 5-9 working day CNC sample timing applies only after scope, material, inspection, partner route, and schedule are qualified. Pilot support is scoped separately after prototype assumptions are clear.
