You send the drawing. We build the heat sink.
Your custom extruded heat sink with spring clip is machined to your exact dimensions, then verified before shipment. No surprises. No rework on your line.
We are a precision manufacturing factory in Dongguan, China, with 20 years on CNC machining, metal stamping, springs, and heat sinks. One factory. One responsible team.
| Parameter | Value |
|---|---|
| Material | Aluminum 6063-T5 (standard), 6061-T6 (higher strength) |
| Extrusion profile | Custom die, max width 300 mm, max length 3000 mm |
| Spring clip material | Stainless steel 301 or 302, full hard |
| Clip finish | Passivated or nickel-plated |
| Tolerance | ±0.05 mm on machined faces, ±0.1 mm on extrusion |
| Surface finish | Ra 1.6 µm on mating surfaces, Ra 3.2 µm elsewhere |
| Anodize thickness | Class II, 18–25 microns (clear or black) |
| Machining | CNC milling, drilling, tapping, countersinking |
| Secondary ops | Deburring, chamfering, thermal interface material (TIM) application |
| Inspection | 100% dimensional check on critical features, CMM report per batch |
| Batch size | No MOQ — prototype to high volume |
| Lead time | 10–15 days prototype, 20–25 days production |
| Packaging | Anti-static foam, individual slots, export carton |
1. Batch-traceable quality Every heat sink gets a unique batch number. We track material lot, machine operator, and inspection results. If a problem shows up on your line, we trace it in minutes, not days.
2. Inspection report per batch You get a full dimensional report with every shipment. Critical features — clip slot width, mounting hole position, flatness — are measured and recorded. You do not need to re-inspect on arrival. Trust, but verified.
3. One factory for CNC + stamping + spring + heat sink Your heat sink has a spring clip. The clip is stamped. The spring is formed. The base is extruded and machined. Most suppliers outsource two or three of these steps. We do all of them in-house. That means fewer handoffs, tighter tolerances, and one point of contact for quality.
Extruded heat sinks with spring clips are standard in power electronics.
If your application runs hot and needs repeatable mounting pressure, this is the part.
Looking for a different part? We also machine Custom Aluminum Extrusion Heat Sink Profiles | Precision Manufacturing No MOQ in the same Dongguan factory.
Q: What is your MOQ? A: No MOQ. We make 1 prototype for your test, or 10,000 for production. Same quality system, same inspection.
Q: What tolerance can you hold on the clip slot? A: ±0.05 mm on the slot width and depth. The clip is stamped to ±0.03 mm. We verify both with a go/no-go gauge before packing.
Q: What is your lead time for a production order? A: 20–25 working days after drawing approval. Prototypes in 10–15 days. If you need faster, tell us — we can split the batch and ship partials.
Q: Do you provide material certificates? A: Yes. Mill certificates for aluminum and stainless steel come with every batch. Anodize thickness reports are included on request.
