Send us your drawing. We machine your round radial aluminum heatsink to print, verify every critical dimension, and ship only after inspection.
We are a precision manufacturing factory in Dongguan, China, with 20 years in CNC machining, metal stamping, springs, and heat sinks. One shop, one quality standard.
| Parameter | Value |
|---|---|
| Material | Aluminum 6063-T5, 6061-T6, or 5052 (per your spec) |
| Process | CNC turning, CNC milling, or die casting + CNC finishing |
| Diameter range | 20 mm to 300 mm |
| Fin height | 5 mm to 80 mm |
| Fin thickness | 1.0 mm to 5.0 mm (as drawn) |
| Tolerance | ±0.05 mm on critical features; ±0.1 mm general |
| Surface finish | Black anodize (MIL-A-8625 Type II), clear anodize, bead blast, or as drawn |
| Flatness | ≤0.1 mm on mounting surface |
| Batch size | 1 to 50,000+ pieces |
| Inspection | 100% critical dimension check per batch; CMM report on request |
We use CNC lathes with live tooling for complex radial fin geometries. For high-volume parts, we combine die casting with CNC finishing to cut cost without losing accuracy. Every batch is traceable to material lot and machine operator.
1. Batch-traceable quality Each order gets a unique batch number. We record material heat number, machine used, and inspector ID. If a problem appears in your assembly line, we trace it back in minutes — not days.
2. Inspection report per batch You get a dimensional report with every shipment. It lists fin height, fin pitch, mounting surface flatness, and surface finish. No surprises. No "we checked it, trust us." You see the numbers.
3. One factory for CNC + stamping + springs + heatsinks Your heatsink might need a stamped clip, a compression spring, or a CNC-machined base plate. We do all four in-house. You deal with one supplier, one invoice, one quality system. Fewer vendor audits, faster lead times, lower logistics cost.
Round radial aluminum heatsinks are built for confined spaces where airflow is axial or natural convection. Common applications:
If your application needs a custom hole pattern, threaded inserts, or a specific mounting boss, we machine it in the same setup. No extra handling, no tolerance stack-up.
Looking for a different part? We also machine Custom Round LED Bulb Heatsink | Precision CNC Machining, No MOQ in the same Dongguan factory.
Q: What is your MOQ? A: No MOQ. We make one prototype for your test, then scale to your volume. Tooling cost is quoted separately only for die-cast parts; CNC-machined parts have zero tooling charge.
Q: How do you control tolerance and quality? A: We use CNC machines with ±0.01 mm repeatability. For every batch, we measure fin pitch, height, and mounting flatness with a CMM. The inspection report is included in the shipment. If a dimension is out of spec, we rework or remake at no cost.
Q: What is your lead time? A: Prototypes in 7–12 days after drawing approval. Production runs in 15–20 days, depending on quantity and surface finish. For urgent orders, we can split the batch and ship partials.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for aluminum 6063-T5 or 6061-T6 with every production order. Certificates show chemical composition and mechanical properties. For anodized parts, we include a thickness test report.
