Vacuum-Brazed Cold Plate
Internal fins and channels are enclosed through controlled brazing for high heat-transfer area and compact flow paths.
Custom Liquid Cooling Cold Plates
We engineer and manufacture liquid cooling cold plates around your heat load, flow target, pressure drop, envelope, mounting pattern, sealing method, and production volume. Our team connects thermal requirements with a practical machining, joining, finishing, inspection, and leak-testing route.
Custom Liquid Cooling Plates for Thermal Management
A cold plate is not only a machined block with channels. Channel geometry, contact flatness, coolant compatibility, port position, sealing, joining method, pressure capability, and installation load all influence performance. We review the full assembly before selecting the manufacturing route.
For prototypes, we help identify the fastest construction that can validate thermal and hydraulic behavior. For production, we focus on repeatable channel geometry, controlled joining, traceable leak testing, clean internal passages, and stable mounting interfaces.

Liquid Cooling Cold Plate Types
We select the construction method according to heat flux, pressure, channel complexity, cleanliness, material, joining risk, and expected production volume.
Friction-Stir-Welded Cold Plate
A machined channel cover is joined with low distortion and no filler metal, supporting strong aluminum thermal assemblies.
Tube-in-Plate Cold Plate
Copper or stainless tubing is embedded into a machined aluminum plate for practical routing and fluid isolation.
Deep-Hole-Drilled Cold Plate
Intersecting drilled passages create sealed internal circuits for robust blocks, manifolds, and compact tooling plates.
Liquid Cooling Cold Plate Design Review
We start with the heat source and assembly, then work inward toward the flow path. This keeps thermal performance, pressure integrity, manufacturability, and inspection connected.
Heat Source and Contact Area
We review heat flux, component footprint, thermal interface material, mounting load, and allowable temperature rise.
Channel and Pressure Drop
Channel width, depth, turns, fins, inlet distribution, and coolant viscosity are balanced against pump capability.
Sealing and Joining
O-ring grooves, cover plates, brazed joints, weld paths, ports, and pressure boundaries are reviewed together.
Flatness and Installation
Machining sequence, joining heat, finishing thickness, mounting pattern, and final inspection affect contact flatness.
Materials and Surface Finishes for Liquid Cooling Plates
We match thermal conductivity, corrosion behavior, coolant chemistry, weight, joining compatibility, and finish requirements to the operating environment.
6061 Aluminum
Our common choice for machinability, low mass, thermal performance, anodizing response, and broad material availability.
Copper C110
Selected where very high thermal conductivity justifies additional weight, cost, and surface-protection considerations.
Stainless Steel
Used for corrosion resistance, pressure hardware, fittings, and applications where coolant compatibility is critical.
Protective Finishes
Anodizing, electroless nickel plating, passivation, conversion coating, and selective masking are reviewed against the coolant loop.
Liquid Cooling Cold Plate Manufacturing and Quality Control
We define inspection and testing before production so critical thermal, hydraulic, and assembly features remain connected to the drawing.
- CMM inspection for mounting patterns, ports, datums, profile, and sealing geometry
- Flatness and surface-finish verification on thermal contact faces
- Pressure decay, hydrostatic, or helium leak testing according to project risk
- Internal cleaning, drying, protection, and packaging for fluid circuits
- Material certificates, finishing records, first-article and dimensional reports
