Description

CPU cold plates look simple until you measure one against a heat-load target. We machine copper and aluminium plates with milled or skived micro-channels, jet-plate impingement patterns or a plain serpentine channel, depending on what your pump can actually push. Flatness on the contact face is held to 0.01 mm and the mounting hole pattern is machined to your socket pitch, so the block seats evenly instead of rocking on one corner.

Frequently asked questions

How do you protect my design?

We sign an NDA before you send anything sensitive. Drawings are stored on an access-controlled server and only the programmers and operators assigned to your part can open them.

What file formats do you accept?

STEP (.stp/.step) or IGES (.igs) for 3D, PDF or DWG for 2D drawings with tolerances and surface finish. If you only have a physical sample, we can reverse-engineer it — and a photo with the key dimensions is enough for a budget estimate.

What tolerances can you hold?

Standard machining tolerance is ±0.05 mm, and ±0.01 mm on features you mark as critical. Locating bores can be held to H7. Tell us which dimensions actually matter — over-tolerancing is the fastest way to raise cost without improving the part.
