Overview

Build-to-Print Cold Plates for AI Racks.

We machine liquid cold plate bodies, lids and manifolds to your drawing: milled channels, CMM-verified dimensions, measured sealing faces, and leak testing. You own the thermal design; we own the metal. See the aluminium cold plates for AI-server cooling made this way.

Work is 3-, 4- and 5-axis CNC machining, finishing, and assembly and leak testing. Channel width, wall thickness, fin pitch and base flatness come from your drawing, reviewed in DFM before quoting. Parts are made at the Dongguan factory under ISO 9001 control. Send a STEP or IGES file plus a 2D GD&T drawing to request a quote for your cold plate. Smaller thermal parts follow the same route as consumer electronics CNC machining.

Questions.

Still looking for something? Our team answers within one business day.

Ask a Question
  • Which lid joining methods do you run on cold plates?

    Joining is set by your design. We machine the body and lid, including O-ring grooves, sealing faces and screw patterns, and we cover welding on sheet-metal parts plus assembly and testing. Name your joining route when you send the drawing and we confirm what fits before quoting.

  • Can you hold flatness on a large cold plate base?

    Flatness is a callout on your drawing, measured on a CMM in the first-article report. ±0.005 mm is our headline machining tolerance, feature-dependent, not a flatness promise. Large thin bases are reviewed in DFM, and the achievable value is confirmed before we quote.

  • How clean are machined cold plates when they ship?

    Ultrasonic cleaning, spray washing and deburring are available, so chips and burrs do not stay in the channels. Packing uses plastic trays and bags, and packaging can be tailored. State any cleanliness requirement on the drawing.

  • What files do I send for a cold plate quote?

    A STEP or IGES model plus a 2D drawing with GD&T is ideal. Other formats are accepted if they open in SolidWorks, ProE or AutoCAD. An NDA can be signed before any drawing is opened.

  • What are your lead times?

    Prototypes can ship in as little as 3 days, with 2–3 weeks typical. Production runs typically take 4–6 weeks. Rush options are available on many jobs and are confirmed per quote.

  • What tolerances and documents come with the parts?

    Tolerances to ±0.005 mm are achievable per feature, depending on the geometry. Each lot ships with a material certificate and inspection record, and a CMM first-article report is sent before the batch starts.
