Your drawing defines the part. Our machines do the rest. We produce corrugated fin heat sinks exactly to your PDF or STEP file, with every critical dimension verified before shipment. No guesswork, no tolerance drift.
At a glance: ±0.05 mm machining tolerance on fin pitch and base flatness, 7-day standard lead time for prototypes, no MOQ for production orders, 100% dimensional inspection on request.

| Batch size | 1 piece to 100,000+ pieces |
| Lead time | 7 days for prototypes, 15-20 days for production |
All corrugated fin heat sinks are made from certified raw material. We keep mill test certificates for every coil and plate lot. If your drawing specifies a particular alloy temper, we match it.
1. Batch-traceable quality. Every heat sink gets a unique job number. That number links to material certs, machine operator logs, and inspection results. If a problem appears in your field, we trace it to the exact batch in minutes. This is precision manufacturing, not job-shop guessing.
2. Inspection report per batch. You get a PDF with CMM points, fin density counts, and surface finish readings. We measure what matters: fin-to-base bond integrity, flatness, and hole positions. For high-volume orders, we use statistical process control on critical features. No extra charge for standard reports.
3. One factory for CNC + stamping + spring + heat sink. Your assembly may need a stamped mounting bracket, a compression spring for retention, and a CNC-machined base plate. We make all of it under one roof. You avoid the headache of coordinating three suppliers across time zones. One purchase order, one quality standard, one shipping date.
Corrugated fin heat sinks appear wherever air moves and heat must leave. Common applications include:
If your application needs forced convection, natural convection, or liquid cooling, send the drawing. We will recommend the right fin pitch and base thickness.

Q: Do you really have no MOQ? A: Yes. We run one prototype or one million pieces. The unit price for a single piece is higher, but the tooling cost is zero for most corrugated designs. You pay only for material and machine time.
Q: How do you guarantee tolerance and quality? A: We use CNC machines with ±0.01 mm positioning accuracy. For fin pitch and flatness, we inspect with a CMM and a surface plate. Every batch gets a report. If a dimension fails, we rework or scrap at our cost, not yours.
Q: What is the typical lead time? A: Prototypes ship in 7 days after drawing approval. Production runs take 15-20 days, depending on quantity and surface treatment. For urgent orders, we can split shipments—first 20% by air, the rest by sea.
Q: Can you provide material certificates? A: Yes. We supply EN 10204 3.1 mill certificates for aluminum and copper. For medical or automotive applications, we also provide RoHS and REACH declarations.
