Your drawing becomes a finished stamped zigzag heatsink in 15 days. We cut, form, and inspect every part to your print—not to a catalog standard. Before shipment, each batch gets a dimensional report and a surface finish check. If it doesn’t match your tolerance, it doesn’t leave Dongguan.
At a glance: ±0.05 mm stamping tolerance, 15-day lead time, no MOQ, batch-traceable from coil to carton.
We run stamped zigzag heatsinks on 25-ton to 160-ton high-speed presses. Material is aluminum 1050, 1060, 5052, or 6061—your call. For higher thermal conductivity, we use 1050 or 1060. For structural rigidity, 5052 or 6061. Fin thickness ranges from 0.3 mm to 2.0 mm. Fin height goes up to 60 mm.
| Parameter | Value |
|---|---|
| Material | Aluminum 1050, 1060, 5052, 6061 |
| Fin thickness | 0.3 – 2.0 mm |
| Fin height | Up to 60 mm |
| Stamping tolerance | ±0.05 mm |
| Flatness (base) | ≤ 0.1 mm over 100 mm |
| Surface finish | Bare, clear anodize, black anodize, or chromate |
| Max part size | 300 mm × 300 mm |
| Tooling | In-house, custom die from your 3D or 2D file |
| Lead time | 7 days for samples, 15 days for production |
| MOQ | No MOQ—order 10 or 10,000 pieces |
| Inspection | CMM + optical comparator, report per batch |
We also offer post-stamping options: deburring, tapping, riveting, or attaching a spring clip. All done in the same factory.
2. Inspection report per batch. You don’t take our word. After stamping, we measure critical dimensions on a CMM and check surface finish with a profilometer. You receive a PDF report with actual values, not just a pass/fail line. If you need first-article inspection (FAI) with PPAP documents, we do that too.
3. One factory for CNC + stamping + spring + heatsink. Your stamped heatsink might need a CNC-machined base, a spring clip, or a threaded insert. We do all four lines under one roof. No third-party handoffs, no miscommunication, no extra freight. You send one drawing set; we deliver a fully assembled part.
Stamped zigzag heatsinks are common in power electronics and LED lighting. You’ll find them in:
If your application needs natural convection cooling in a tight space, a stamped zigzag heatsink is often the cheapest, lightest option.
Q: How do you guarantee tolerance and quality? A: We use hard tooling (not soft dies) for repeatability. Every batch is checked on a CMM. We provide a dimensional report and material certificate with each shipment. If a part is out of spec, we replace it at no cost.
Q: What is your lead time? A: Samples in 7 days after tooling approval. Production in 15 days for standard sizes. For urgent orders, we can split shipments—send what’s ready first, then the rest.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for aluminum coils and any required RoHS or REACH declarations. For automotive or medical projects, we also provide full traceability documents.
