01 / What We Fabricate
Cold Plates Built Around Real Thermal Interfaces
Cooling-plate buyers need controlled channels, port geometry, flatness and leak-test evidence for the heat-transfer plate itself, separate from the manifold or surrounding enclosure.
Internal Flow Paths
Channel geometry, cover plates and joined seams follow the released thermal design and approved manufacturing route.
Ports and Connections
Inlet and outlet bosses, fittings and tube interfaces are located and inspected against assembly datums.
Leak-Tested Delivery
Pressure or leak testing, drying, cleanliness protection and revision records are supplied to the agreed RFQ scope.
Our scope: build-to-print cold plate manufacturing and inspection
The OEM owns channel design, thermal simulation, coolant selection, flow and pressure targets, battery or electronics safety, and final system validation. DRAmetal manufactures the released cold plate assembly to the agreed material, joining, inspection, test and cleanliness requirements.

04 / Manufacturing Process
From Released Thermal Design to Leak-Tested Plate
01
Drawing and Duty Review
Confirm plate envelope, coolant, pressure, ports, mounting datums, flatness, cleanliness and required records.
02
DFM and Route Planning
Review channel access, braze lands, alloy compatibility, distortion risk, fixture strategy and test connections.
03
Plate and Port Fabrication
Machine or form channel features, prepare covers and fabricate bosses, tubes or port hardware to the released design.
04
Controlled Joining
Join the plate assembly with the approved vacuum-braze or drawing-defined process and controlled fixturing.
05
Dimensional and Leak Inspection
Verify contact geometry, mounting and port datums, then perform the specified pressure or leak-test sequence.
06
Clean, Seal and Pack
Dry internal paths, protect contact faces, seal ports and pack each plate by lot and drawing revision.
05 / Why It Matters
Controls That Protect Cooling Performance
A cold plate can look acceptable while still failing through distortion, port misalignment, internal contamination or a leak path. Manufacturing controls must follow the thermal and mechanical interfaces together.
Contact Flatness
Distortion at the battery or power-device face increases interface resistance and can create uneven temperatures.
Joined-Seam Integrity
Channel covers and port joints need a qualified route, controlled surfaces and an agreed leak-test method.
Flow-Path Cleanliness
Braze residue, chips or trapped moisture can contaminate pumps, valves and downstream system hardware.
Port and Mounting Datums
Coolant connections and mounting holes must align with the module without forcing hoses or distorting the plate.

09 / FAQ
Liquid Cooling Cold Plate FAQ
What cold plate applications can DRAmetal support?
Typical RFQs include BESS battery modules, EV module plates, robotics drives, power electronics and other industrial liquid-cooled hardware built to released drawings.
Can you vacuum-braze aluminum cold plates?
Vacuum-brazed construction can be supported when it matches the drawing, alloy system and qualified manufacturing route. Final process and test requirements are confirmed during RFQ review.
How are cold plates tested for leaks?
Testing may use pressure hold, air decay, water immersion or helium methods depending on the specified pressure, allowable leak rate and customer test standard.
Do you design the thermal channels?
We normally manufacture to the customer's released thermal design. DFM feedback can address manufacturability, joining access, distortion and testability, while thermal sizing and system validation remain with the OEM.
What information is needed for a cold plate quote?
Send 2D drawings, 3D models, alloy requirements, channel and port details, coolant, working and test pressure, leak-rate limit, flatness, cleanliness, finish, records and quantities.
