Your round LED bulb heatsink, made to your exact drawing. We machine it, verify it, and ship it with a full inspection report. No guesswork, no surprises.
At a glance: CNC machined tolerance ±0.05 mm, surface finish Ra 1.6, lead time 7–12 days, no MOQ. Aluminum 6061-T6 or 6063-T5, anodized black or clear. We make what you specify, and we prove it before the box leaves Dongguan.
| Parameter | Value |
|---|---|

| Process | 4-axis CNC machining, CNC turning, or die-casting + CNC finishing |
| Tolerance | ±0.05 mm on critical dimensions, ±0.1 mm general |
| Surface finish | Ra 1.6 machined, Ra 0.8 on sealing faces |
| Surface treatment | Clear anodize, black anodize, or hard anodize (per your spec) |
| Fin options | Straight fins, pin fins, or spiral fins (custom profile) |
| Max diameter | 300 mm (larger on request) |
| Max height | 150 mm |
| Thread options | E26, E27, GU10, or custom thread per drawing |
| Batch size | 1 piece to 100,000+ pieces |
| Lead time | 7 days for prototypes, 12 days for production batches |
| Inspection | CMM report, dimensional report, and surface finish check per batch |
| Certifications | Material certs (EN 10204 3.1), RoHS, REACH |
We run our own CNC line, so we control every cut. No outsourcing, no middlemen. If your drawing calls for a 0.05 mm tolerance on the mounting boss, that is what you get.
1. Batch-traceable quality. Every heatsink gets a unique batch number. We track material lot, machine, operator, and inspection results for that batch. If you need to trace a part back to its raw material, we give you the full chain in one PDF.
2. Inspection report per batch. You do not have to trust us. Each shipment includes a dimensional report, a CMM check on critical features, and a surface finish reading. We measure what matters to your thermal performance—flatness of the mounting face, fin height, and thread pitch.
3. One factory for CNC, stamping, springs, and heatsinks. Your LED bulb assembly might need a stamped reflector, a spring contact, and a machined heatsink. We make all three under one roof. That means one purchase order, one quality system, and one shipping date. Fewer suppliers, fewer delays, fewer arguments.
Round LED bulb heatsinks go into everyday lighting and demanding industrial fixtures. Common applications include:
If your product generates heat and uses a round LED source, we have machined a heatsink for something like it. Send us your drawing, and we will tell you if it is manufacturable—and how we would make it better.

Q: Is there really no MOQ? A: Yes, no MOQ. We machine one prototype for your thermal test, or we run 50,000 pieces for production. The unit price drops with quantity, but we never turn away a single-piece order.
Q: How do you guarantee tolerance and quality? A: We set up every job with in-process inspection. After machining, we run a CMM check on critical dimensions and a surface profile test. You get the report with the shipment. If anything is out of spec, we re-make it at our cost.
Q: What is your lead time for custom heat sinks made in China? A: Prototype parts ship in 7 days after drawing approval. Production batches ship in 12 days. For repeat orders, we hold your tooling and CNC programs, so lead time drops to 7 days.
Q: Can you provide material certificates? A: Yes. Every batch comes with a mill certificate for the aluminum or copper, plus RoHS and REACH declarations. If your customer requires EN 10204 3.1, we provide it.
Stop specifying from a catalog. Send us your round LED bulb heatsink drawing, and we will give you a firm quote in 12 hours. We will confirm material, tolerance, surface finish, and price—no vague estimates.
