Your drawing. Our machines. A heatsink that fits exactly where it must.
We machine and stamp aluminum heatsinks with mounting bases to your print. Every unit is checked before shipment—dimensions, flatness, hole positions. No surprises on your assembly line.
| Parameter | Value |
|---|---|
| Material | Aluminum 6063-T5, 6061-T6, 5052, or per your spec |
| Manufacturing process | CNC machining, CNC milling, stamping, skiving, extrusion |
| Tolerance | ±0.05 mm (machined), ±0.10 mm (stamped) |
| Surface roughness | Ra 0.8–1.6 µm on mating surfaces |
| Surface treatment | Anodizing (black, clear), powder coating, nickel plating, passivation |
| Mounting base | Integrated or press-fit, hole pattern per drawing |
| Fin options | Extruded, stamped, or folded fins; fin pitch 2.5–10 mm |
| Maximum size | 600 mm × 400 mm × 150 mm (CNC), 300 mm × 200 mm (stamping) |
| Inspection equipment | CMM, optical comparator, surface profilometer |
| Batch traceability | Full lot code, material heat number, process records |
| Lead time | Prototype 7–12 days, production 15–20 days |
| MOQ | No MOQ—prototype to mass production |
| Country of origin | Made in China, Dongguan factory |
1. Batch-traceable quality. Every heatsink gets a lot code. We record the material heat number, machine settings, and inspection results for that lot. If a problem appears in your field, we trace it back in hours, not weeks.
2. Inspection report per batch. You get a dimensional report with each batch—flatness, hole positions, surface finish, and material hardness. We measure with a CMM and surface profilometer. The report is signed by our QC lead. No vague "passed" stamps.
3. One factory for CNC + stamping + springs + heatsink. Your heatsink may need a stamped mounting bracket. Or a spring clip to hold the fan. Or a machined base plate. We do all four lines under one roof. You send one drawing package, get one quote, one shipment, one responsible supplier. No coordinating multiple vendors.
Our heatsinks with mounting bases go into equipment that runs hot and runs long.
If your application is different, send the drawing. We will tell you if we can make it—and how.

Q: Do you really have no MOQ? A: Yes. We run prototype quantities of 1–5 pieces for fit testing. Production runs start at 100 pieces. The unit price drops with volume, but the quality process is identical.
Q: What tolerance can you hold on the mounting base? A: Machined surfaces hold ±0.05 mm. Stamped features hold ±0.10 mm. If you need tighter, we can grind the base face to ±0.02 mm—but that adds cost and lead time.
Q: What is the typical lead time? A: Prototypes ship in 7–12 days after drawing approval. Production orders take 15–20 days. We can rush prototypes in 5 days for an expedite fee.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for the aluminum alloy and heat treatment. For medical or aerospace, we add full traceability documentation at no extra cost.
Email your PDF or STEP file. We will check the geometry, suggest improvements if needed, and send a firm quote within 12 hours.
No MOQ. No hidden tooling costs. No vague promises.
