Thermal Management Components

CNC Machining for AI Server Liquid Cooling Components

Drawing-based manufacturing support for custom cold plates, liquid cooling manifolds, distribution blocks, connector bodies, and precision sealing interfaces.

Custom Liquid Cooling Components

We review the complete part definition—material, channels, datums, sealing features, joining route, finish, cleanliness, inspection, and test requirements—before confirming manufacturability.

CNC Machined Cold Plates

Base plates and covers with processor contact faces, internal channels, O-ring grooves, ports, fastener patterns, and joining interfaces.

Explore cold plate machining

Liquid Cooling Manifolds

Distribution blocks with intersecting passages, threaded ports, sealing lands, mounting datums, plugs, and internal deburring requirements.

Explore manifold machining

Connectors and Housings

Connector bodies, quick-disconnect interfaces, pump housings, valve bodies, brackets, and related precision fluid hardware.

Material and Process Planning

DecisionManufacturing consideration
Aluminum or copperBalance thermal conductivity, mass, corrosion strategy, strength, joining, finishing, machining time, and cost.
Channel geometryConfirm cutter access, corner radii, floor condition, burr control, pressure drop, and cleaning verification.
Sealing strategyDefine O-ring groove standard, surface condition, fastener pattern, gasket compression, and post-finish dimensions.
Joining routeAccount for brazing, welding, bonding, soldering, or mechanical closure in the datum and tolerance plan.
Inspection and testingAgree dimensional reporting, leak method, test medium, pressure, hold time, flow criteria, cleanliness, and traceability.

Manufacturing Workflow

01

Engineering Review

Review CAD, drawing, datums, material, finish, joining, quantity, inspection, and functional test inputs.

02

Process Development

Plan stock, setups, fixtures, tools, channel strategy, thermal control, cleaning, and measurement methods.

03

First Article

Validate dimensions, surface condition, internal passages, assembly interfaces, and agreed functional tests.

04

Controlled Production

Apply revision control, in-process checks, tool-life rules, final inspection, documentation, and protected packing.

Characteristics Commonly Reviewed

Thermal Interface

  • Contact-face flatness or profile
  • Surface roughness and damage limits
  • Wall thickness and material condition
  • Coating or plating buildup

Fluid Circuit

  • Channel width, depth, and intersections
  • Port and thread location
  • Burr and particle control
  • Flow and pressure-drop criteria

Sealing and Assembly

  • Groove geometry and sealing lands
  • Cover and manifold alignment
  • Fastener pattern and thread quality
  • Leak and proof-pressure tests

Quality and Test Planning

Inspection is tailored to the drawing and risk. CMM, optical measurement, gauges, roughness measurement, visual verification, leak testing, pressure testing, and flow testing may be used where specified and technically appropriate.
