Your drawing defines the part. Our job is to make it exactly that. We machine, stamp, and assemble heat sinks to your print—tolerance held, surface finished, and dimensions verified before the box leaves our floor.
We are a precision manufacturing factory in Dongguan, China, with 20 years on CNC, stamping, springs, and heat sinks. You send the drawing. We send a quote. Then we make the part.
| Parameter | Value |
|---|---|
| Materials | Aluminum 6063-T5, 6061-T6, 5052, copper C1100, or per your spec |
| Processes | CNC milling, CNC turning, die casting, extrusion, stamping, skiving |
| Tolerance | ±0.05 mm (CNC), ±0.1 mm (stamping), flatness 0.1 mm per 100 mm |
| Surface finish | Black anodize (8–12 µm), clear anodize, nickel plating, powder coat, or bare |
| Fin height | 3 mm to 80 mm, aspect ratio up to 15:1 for skived fins |
| Base thickness | 2 mm to 25 mm, optional heat pipe or vapor chamber slots |
| Thermal performance | Verified by CFD simulation on request, or by your test data |
| Batch size | 1 to 100,000+ pieces, no MOQ |
| Inspection | CMM report, 2D profile check, hardness test, anodize thickness gauge |
| Packaging | Anti-static foam, individual slots for fragile fins, export carton |
We run 3-axis and 4-axis CNC mills, plus stamping presses up to 250 tons. For high power LED heatsinks, we often combine extrusion with CNC finishing to keep cost low and fins straight.
2. Inspection report per batch. You get a dimensional report, material cert, and surface finish reading with every shipment. Not a generic PDF—actual measured values from our CMM and profilometer. We keep records for 5 years.
3. One factory for CNC + stamping + spring + heatsink. Your LED assembly might need a stamped bracket, a spring clip for the lens, and a machined heatsink. We make all three under one roof. Fewer suppliers, fewer tolerance mismatches, one shipping address.
In each case, the heatsink is the reliability bottleneck. If it runs 10°C hotter than the design, LED life drops by half. We machine to the thermal spec, not just the dimensional one.
Q: How do you control tolerance and quality? A: First article inspection on every new drawing, then in-process checks every 2 hours on critical dimensions. Final CMM report on 5% of the batch, or 100% if you request it. We hold ±0.05 mm on CNC features and ±0.1 mm on stamped parts.
Q: What is your lead time? A: Prototypes ship in 7–15 days from drawing approval. Production runs ship in 15–25 days, depending on surface treatment. Anodize adds 3–5 days. We confirm a firm date in the quote.
Q: Do you provide material certificates? A: Yes. Mill test reports from the aluminum supplier are included with every batch, free. If you need third-party testing (SGS, TÜV), we arrange it at cost.

Your drawing is safe with us. We sign NDAs on request, and we never share your design with third parties. Precision manufacturing, custom heat sinks, made in China—with the paperwork to prove it.
