A heat sink for M.2 SSD is pressed in one piece from copper-alloy CuZn37 on 25 T tooling, holding ±0.03 mm repeatability and 0.10 mm flatness over 100 mm. It delivers 1.10 K/W at ΔT = 60 K with clear anodize Type II, 5-10 µm, and supports 300,000 pcs programs at an 18 s cycle. Weight starts from 280 g depending on envelope.

Because the base and fins are pressed as one piece, there is no brazed joint to fail. 0.10 mm over 100 mm flatness on the mounting face is held directly from the tool, which keeps thermal interface contact uniform.
A single 25 T stroke forms the whole heat sink for m.2 ssd, so part cost stops scaling with complexity. Tooling runs ±0.03 mm, and the 18 s cycle feeds a 300,000 pcs line.
One supplier now covers 1.0 mm to 1.0 mm fin gauges from the same 25 T press family, so a thermal redesign is a tooling change rather than a new vendor.
Pressing copper-alloy CuZn37 keeps the heat sink for m.2 ssd light, from 280 g depending on envelope, without sacrificing fin density, which matters where airflow path length is already fixed by the enclosure.

Every stroke is dimensionally identical, so ±0.10 mm hole position carries across the batch. That is what makes industrial PLC and control cabinet volume programs repeatable.
The standard material is copper-alloy CuZn37, supplied with clear anodize Type II, 5-10 µm. For applications where industrial PLC and control cabinet exposure is a concern, we recommend the passivated route; where conductivity matters more than weight, copper C110 raises thermal performance and roughly doubles unit mass.

General dimensions run to ±0.15 mm, with critical features such as ±0.05 mm on mounting hole position held separately. Formed geometry inherits tooling repeatability of ±0.03 mm, and hole position is held to ±0.10 mm. Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.
Incoming copper-alloy CuZn37 is checked for thickness and hardness before it enters the press. After forming, CMM plus 100% hydraulic press leak test confirms 0.10 mm over 100 mm and 1.5 mm against the drawing.

Lot traceability runs from coil to carton: heat number, press stroke range and inspection record stay attached, so a field issue can be tied back to a specific run.
Flatness is measured on granite rather than on cast iron, because 0.10 mm over 100 mm at 200 x 100 x 80 mm reads differently on a plate that has not been lapped. Records keep both readings.

Final containment is Anti-static bag + wooden crate over 50 kg. Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.
industrial PLC and control cabinet customers typically specify copper-alloy CuZn37 for corrosion reasons and then hold the drawing to ±0.15 mm. The 300,000 pcs line absorbs the volume without a second source.
Where a heat sink for m.2 ssd runs at industrial PLC and control cabinet volumes, part-to-part consistency decides field returns. ±0.03 mm on a 300,000 pcs run keeps the thermal curve inside one band.
Designers working on industrial PLC and control cabinet ask for flatness before they ask for thermal data, because industrial PLC and control cabinet assembly is automated and a non-flat base stops the line.
For industrial PLC and control cabinet prototypes, 72 hours covers drawing review and first article. Production lots move to 15 working days once the ±0.03 mm capability is signed off.

Every lot is inspected with CMM plus 100% hydraulic press leak test, and the report is included in the shipment. We check 0.10 mm over 100 mm, 1.5 mm, 3.0 mm and hole position against ±0.15 mm. Lot traceability from coil to carton is kept for 10 years.
Extrusion is cheaper above roughly 500,000 pieces per year and gives a smoother profile. Stamping wins below that and wherever fin gauge drops below 0.5 mm, because extrusion cannot hold 1.0 mm consistently. For industrial PLC and control cabinet prototypes, tooling cost usually decides it.
Yes. Standard is clear anodize Type II, 5-10 µm. Powder coating to RAL 9005 adds about 0.1 mm to the base; zinc-nickel is better for grounding. Note that any added coating sits between copper-alloy CuZn37 and the airflow, so we do not coat the fin roots.
We supply a 2D drawing with the CMM report, and 3D STEP on request. Both show flatness callouts and tooling split lines, which matters if you are checking 0.10 mm over 100 mm in your own assembly.

Skived fins are milled, so you get thin, tall fins and higher density in a given height, but the cost scales directly with fin area. Stamping gives the same result in one stroke at a much lower unit cost below 300,000 pcs. For industrial PLC and control cabinet in a fixed-height enclosure, stamped is normally the right answer.

Our industrial PLC and control cabinet experience runs back to the first tooling programme in 2015. That history is why the standard clear anodize Type II, 5-10 µm and ±0.15 mm are conservative rather than optimistic.
The factory holds ISO9001 and can ship RoHS and REACH documentation with the Anti-static bag + wooden crate over 50 kg. Third-party SGS inspection is arranged on request before the container is sealed.
Tooling is built in-house, which is how ±0.03 mm is held across a 300,000 pcs programme rather than drifting part by part.
