CDU & Custom Manifolds, Engineer-to-Order
Send a drawing, get a DFM review within 48 hours, and hold one supplier from bar stock to tested assembly: bores DN03–DN10, UQD/UQDB port interfaces, and every batch leaving with helium and pressure records inside the carton.
From your drawing to a tested batch in six steps.
Each step states what we do and what we need from you — no silent hand-offs, no surprise gates.
Drawing intake
You send a PDF plus STEP/IGES with loop conditions: flow per branch, ΔP budget, coolant and temperature range. We confirm interface sizes and the port map in writing before anything is costed. Your part: the current-rev drawing and target quantities.
DFM review · 48 h
Within 48 hours you receive a written DFM report: bore sizing checked against your ΔP budget, wall thickness, seal choices and port interface verification. A 30-minute call walks through the markups. Your part: one call window with your hardware owner.
Prototype
First articles are machined on the same cells that will run the batch, then 100% pressure tested with results reported against the DFM notes. Your part: approve the sample, or mark it up and we cut again.
FAI / PPAP
A ballooned first-article inspection with CMM dimensions — PPAP-format documentation on request for OEM quality gates. Your part: your quality template, so the file lands in your system in your format.
Batch + 100% test
Production runs with per-batch helium / vacuum-decay and pressure records; cleanliness targets the ISO 4406 18/16/13 code. Your part: a release schedule so batches land with your integration calendar.
Ship FOB · CIF · DDP
Packed foam-in-box — individual coupling cartons of 10×10×5 cm at 0.2 kg, manifolds trayed — with the full document set enclosed. Your part: consignee details and preferred terms, quoted FOB, CIF or DDP.
The manifold sits where the pressure budget is tightest.
In-rack CDUs span 15 to 125 kW of cooling, and measured high-density racks put about 56% of total pressure drop inside the server modules themselves. The manifold is the part you can still shape — every bore diameter chosen correctly and every elbow removed buys margin back for the pumps instead of starving the far trays.
- 15 – 125 kW — in-rack CDU range the manifold must follow
- ≈ 56% — share of rack ΔP consumed by server modules in measured racks
- DN03 – DN10 — bore range machined in-house
What engineer-to-order covers.
If your build sits outside a row, send it anyway — the DFM review is where exceptions get priced, not guessed.
