Your drawing. Our machines. A heatsink that fits the first time.
We machine black anodized aluminum heatsinks to your exact print. Tolerances hold at ±0.05 mm on critical mounting surfaces. Every part is verified before shipment—no guesswork, no rework on your line.
At a glance: ±0.05 mm machining tolerance, 7–10 day lead time for prototypes, no MOQ, batch-traceable from raw bar to anodized finish.
| Parameter | Value |
|---|---|
| Material | Aluminum 6061-T6 or 6063-T5 (per your spec) |
| Machining tolerance | ±0.05 mm on critical features; ±0.1 mm general |
| Surface finish | Black anodize (Type II, 18–25 microns) or hard anodize (Type III, 40–50 microns) |
| Flatness | 0.05 mm over 100 mm length |
| Fin options | CNC milled pin fins, extruded + cut, stamped fins, skived |
| Threads/inserts | Rolled threads, heli-coil inserts, press-fit nuts |
| Inspection | CMM report per batch, surface roughness Ra 1.6 µm on mating faces |
| Lead time | 7–10 days prototype, 15–20 days production |
| MOQ | No MOQ—1 piece or 10,000 pieces |
| Certifications | Material certs (EN 10204 3.1), RoHS, REACH |
Processes used: 3-axis and 4-axis CNC milling, CNC turning, precision stamping for fin assemblies, and wire EDM for complex geometries. We control the full chain—machining, deburring, cleaning, anodizing—in one factory.
1. Batch-traceable quality. Each heatsink gets a unique batch number. We track the aluminum lot, machine operator, tool path version, and anodize bath records. If a problem appears in your field, we trace it to the source in minutes, not weeks.
2. Inspection report per batch. You get a CMM dimensional report, surface finish readings, and anodize thickness verification with every shipment. No extra charge. No asking. It’s standard.
3. One factory for CNC + stamping + springs + heatsink. Your assembly might need a stamped bracket, a compression spring, and a machined heatsink. We make all of them under one roof. Fewer vendors, fewer tolerances stacking up between parts, one shipping address. That cuts your procurement time and your risk.
Our black anodized heatsinks go into equipment where thermal management is non-negotiable.
If your part moves heat, we can machine it.

Q: Is there really no MOQ? A: Correct. We run one prototype or a full production batch. For small quantities, we use standard 6061-T6 bar stock to keep costs fair. For large runs, we can switch to 6063-T5 extrusions to reduce material waste.
Q: How do you guarantee tolerance and quality? A: First article inspection on every new drawing—full CMM report. During production, we check critical dimensions every 50 pieces. Final inspection covers 100% of parts for visual defects and a statistical sample for dimensional verification. All reports are sent with the shipment.
Q: What is the actual lead time? A: Prototypes: 7–10 days after drawing approval. Production: 15–20 days, depending on quantity and anodize line schedule. We quote a firm date with your price—no vague promises.
Q: Can you provide material certificates? A: Yes. Every batch comes with EN 10204 3.1 material certificates, plus RoHS and REACH declarations. If your customer requires a specific mill or alloy, tell us and we’ll source it.
