01 / What We Fabricate
Robot-Specific Cold Plates Within Tight Envelopes
A robot-arm cooling plate is more than a general liquid cold plate in a smaller outline. Its mass, mounting face, port direction, hose sweep and service access must fit a moving joint or compact controller without changing the OEM's released interface.
Controller and Servo Plates
Flat, sealed plates for drives, power electronics and control enclosures with defined device contact areas.
Mobile Robot Thermal Plates
Cold plates for batteries, inverters and compute modules inside AMRs, AGVs and compact autonomous platforms.
Custom Channel Hardware
Machined-channel plates, covers, ports and mounting features manufactured to a released thermal and hydraulic design.
Our scope: manufacture the released robot cold plate
The robot OEM or thermal-system designer owns heat load, fluid selection, flow and pressure targets, hose design, condensation control, joint dynamics and full-system validation. DRAmetal manufactures and inspects the released cooling plate to the agreed material, interface, joining and test requirements.
02 / Robotics Cooling Plate Types
Precision Cooling Plates for Robotic Arms and Controllers
The construction, port layout and inspection route are matched to the robot module, sealing method and released test requirements.

04 / Manufacturing Process
From Released Robot Interface to Tested Cooling Plate
01
System Input Review
Confirm the released envelope, mass target, mounting faces, ports, hose zones, fluid compatibility and test plan.
02
Interface and DFM Map
Map device contact areas, joint or controller datums, fastener access, channel walls and sealing lands.
03
Manufacturing Route
Define machining, deburring, cleaning, joining, finishing and inspection sequence for the specified construction.
04
Controlled Fabrication
Machine channels and interfaces, install ports and join the cover while protecting critical faces and internal cleanliness.
05
Dimensional and Leak Test
Inspect released CTQs and complete the specified pressure or leak test with traceable acceptance records.
06
Protected Packout
Cap ports, protect contact faces and keep plate identity, drawings and test records tied to the correct robot revision.
05 / Why It Matters
What Makes a Robotic-Arm Cold Plate Different
A compact plate can pass a basic leak check yet still be unsuitable for a moving robot module. The manufacturing plan must preserve the complete mechanical interface defined by the system designer.
Mass and Envelope
Extra material, protruding fittings or a shifted outline can affect packaging and moving-axis inertia.
Hose Routing
Port position and clocking must respect released bend radius, joint travel and service-removal zones.
Contact-Face Flatness
Cover joining and finish can move a device or joint mounting surface unless flatness is checked at the final state.
Leakage and Cleanliness
Internal debris, damaged threads or an unverified joint can compromise the wider liquid loop after assembly.

Why Robotics OEMs Use DRAmetal for Cooling Plates
01
Integrated metalwork
Channel machining, cover joining, ports, inserts, finishing and inspection are coordinated in one released route.
02
Robot-interface focus
The control plan follows moving-envelope, mounting-face and hose-routing features instead of treating the plate as a generic heat sink.
03
Test-linked records
Part identity can be connected to drawing-defined dimensional, pressure and leak evidence for first article and repeat supply.
04
Variant control
Similar joint, controller and platform plates remain separated by current model, revision, port layout and packout.

09 / FAQ
Robot Arm Cooling Plates FAQ
How is this different from a general liquid cooling cold plate?
This scope focuses on robot-specific compact mass and envelope, joint or controller mounting faces, port direction, hose-motion keep-outs, service access and platform variants. The general cold-plate page covers broader industrial and electronics applications.
Can you design the thermal and hydraulic system?
We support build-to-print manufacturability review, but the robot OEM or thermal-system designer must release and validate heat load, channel performance, fluid, flow, pressure, hose design, condensation controls and system acceptance criteria.
Which cooling plate constructions can be manufactured?
Released designs may use machined-channel plates with sealed covers, brazed or welded construction, threaded or welded ports, inserts and drawing-defined finishes. Material and joining compatibility are reviewed for each RFQ.
How are flatness and leakage controlled?
The route can include datum-based machining and inspection, protected contact faces, controlled cover joining, final flatness checks, internal cleaning and drawing-specified pressure or leak testing.
What should a robot cooling plate RFQ include?
Send 3D models, 2D drawings, material, channel and cover definition, joint or controller interfaces, mass and envelope limits, port and hose zones, fluid compatibility, finish, CTQs, test plan, revisions and quantities.
