Your drawing. Our machines. A verified part before it ships.
We build custom heat sinks to your exact geometry—CNC machined, stamped, or assembled. Every batch is checked against your tolerances, and the inspection report travels with the shipment.
We are a precision manufacturing factory in Dongguan, China, with 20 years on CNC, stamping, springs, and heat sinks. You send the drawing. We do the rest.
| Parameter | Value | Notes |
|---|---|---|
| Materials | Al 6061, Al 6063, Cu C1100 | Other alloys on request |
| CNC machining | 3-axis, 4-axis, 5-axis | Max part size 800 × 600 × 300 mm |
| Stamping | Progressive die, 25–160 ton presses | For fin arrays, clips, mounting brackets |
| Tolerance | ±0.05 mm (CNC), ±0.1 mm (stamped) | Tighter on critical features |
| Surface roughness | Ra 1.6 µm (machined), Ra 3.2 µm (stamped) | As-drawn or improved |
| Surface treatment | Clear anodize, black anodize, Ni plating, passivation | MIL-A-8625, ASTM B117 salt spray on request |
| Fin thickness | 0.8 mm min (stamped), 1.5 mm min (CNC) | Thinner with special tooling |
| Thermal interface | Flatness 0.05 mm over 100 mm | Verified with CMM |
| Batch size | 1–100,000 pcs | No MOQ, tooling amortized per order |
| Inspection | 100% critical dimensions, AQL 2.5 for batch | Report included per batch |
Every heat sink is deburred, cleaned, and checked for burrs on fin edges. We do not ship parts we would not mount on our own equipment.
1. Batch-traceable quality. Each batch gets a unique job number. Material certs, process records, and inspection results are linked to that number. If a problem appears at your assembly line, we trace it to the exact heat treat lot and machine operator. No guesswork.
2. Inspection report per batch. You receive a dimensional report with CMM data, surface finish readings, and flatness measurements. For thermoelectric cooler heatsinks, we also verify the mounting surface flatness—critical for thermal contact. You do not have to re-inspect everything on arrival.
3. One factory for CNC + stamping + springs + heatsink. Your assembly may need a stamped clip, a spring for pressure mounting, and a machined base. We make all of them under one roof. Fewer suppliers, fewer tolerance mismatches, fewer shipping delays. You get one invoice, one quality standard, one responsible party.
Custom heat sinks from our shop cool real equipment:
If your part dissipates heat, we can machine or stamp it.

Q: Do you really have no MOQ? A: Yes. We run one prototype for a quote validation, or 50,000 pieces for production. Tooling costs are quoted separately for stamped parts, but CNC parts have no tooling charge.
Q: What tolerance can you hold on a heatsink? A: ±0.05 mm on CNC-machined features like mounting holes and base thickness. Fin pitch and height are typically ±0.1 mm. For TEC mounting surfaces, we hold flatness to 0.05 mm over 100 mm.
Q: What is your lead time? A: Prototypes ship in 7–15 days after drawing approval. Production runs take 15–25 days, depending on quantity and surface treatment. We quote exact dates when you send the drawing.
Q: Can you provide material certificates? A: Yes. Mill test certificates for aluminum and copper are included with every batch. Anodizing thickness and salt spray test reports are available on request.
Send us your 2D or 3D file. We reply with a firm quote in 12 hours—price, lead time, and tolerances we can hold.
