PRODUCT OVERVIEW

What Are CNC
Machined Cold Plates?

A CNC machined cold plate uses a metal base with precision-milled flow channels and functional features. Once enclosed, the channels circulate coolant beneath heat-generating components, carrying heat away in a compact assembly.

Precision-Machined Channels

Drawing-defined flow paths place coolant where your equipment needs heat removal.

Efficient Heat Transfer

Aluminum or copper conducts heat into the circulating fluid, supporting application-specific cooling targets.

Custom Mechanical Integration

Mounting holes, seal grooves and ports follow your design so the plate fits the surrounding assembly.

Match your thermal requirements to a manufacturable cold plate.

MATERIALS & FINISHING

Choose the Material.
Define the Finish.

Material choice affects heat spreading, weight and production cost. Specifying material and treatment together helps your machined cold plate meet both thermal and environmental requirements.

Aluminum Cold Plates

Typical option: Aluminum 6061. Low weight and good machinability support compact cooling assemblies where manufacturing cost and mechanical integration matter.

Copper Cold Plates

Typical options: Copper C110 / C101. Higher thermal conductivity supports heat spreading in demanding interfaces, with weight and machining requirements reviewed for your design.

Anodizing

Specify suitable aluminum surfaces and coating requirements to provide the intended protection while preserving contact and sealing features.

Nickel Plating

Review plating compatibility and coverage for the required surface properties and coolant environment.

Custom Surface Requirements

Define roughness, treatment exclusions and cleanliness on the drawing so finishing supports assembly and service requirements.

Coolant chemistry, galvanic compatibility, sealing surfaces and thermal contact areas must be considered before any finish is confirmed.

COLD PLATE CONSTRUCTION

Close the Channels.
Define the Sealing Strategy.

A CNC milled cold plate base needs a compatible enclosure to form a closed coolant path. Matching the cover, seal and joining method to operating conditions helps address leakage risks before assembly.

Machined Base & Cover Plate

A compatible cover encloses the milled channels, creating a compact flow path beneath your heat sources.

O-Ring & Gasket Sealing

Drawing-defined grooves locate elastomeric seals in suitable bolted designs, supporting serviceable assemblies where required.

Welded or Brazed Construction

Permanent joining may be evaluated for compatible materials and joint geometry. Confirmed process and test requirements define the production route.

Seal and joint selection must consider coolant chemistry, operating pressure, temperature cycling, assembly loads and required service life.

Define the enclosure and sealing method alongside the machined geometry.
