Your drawing is the starting point. We machine the rest.
Every heat sink in this collection starts as a raw aluminum block or extrusion. We cut, mill, and finish it to your exact print. Before any part leaves our floor, it goes through a full dimensional check on a CMM. You get verified geometry, not a promise.
We are a precision manufacturing factory in Dongguan, China, with 20 years in CNC machining, metal stamping, springs, and heat sinks. One supplier for your thermal and mechanical parts.
| Parameter | Value |
|---|---|
| Material | 6061-T6, 6063-T5, 1050, 1100 aluminum |
| Process | CNC milling, CNC turning, extrusion, skiving, stamping |
| Tolerance | ±0.05 mm standard, ±0.02 mm on request |
| Surface finish | Black anodized (Type II 8–12 µm, Type III 25–50 µm) |
| Flatness | 0.1 mm over 100 mm length |
| Thermal conductivity | 167–201 W/m·K (depending on alloy) |
| Max part size | 600 mm x 400 mm x 150 mm |
| Min fin thickness | 0.8 mm (CNC), 0.3 mm (skived) |
| Fin height | Up to 80 mm |
| Batch size | 1 to 50,000+ |
| Inspection | CMM, 2.5D vision, surface roughness tester |
| Lead time | 7 days for prototype, 15–20 days for production |
All machining is done in-house. We control the process from raw bar to anodized finish. No middlemen, no quality gaps.
2. Inspection report per batch You get a dimensional report with every shipment. Critical features are measured and recorded. The report shows actual values, not just pass/fail. For heat sinks, we include flatness, fin spacing, and anodizing thickness. This saves your incoming QC time and avoids surprises.
3. One factory for CNC + stamping + springs + heat sinks Your heat sink often needs a stamped clip, a spring, or a CNC-machined base plate. We make all of them under one roof. That means one purchase order, one quality standard, and one shipping date. You reduce supplier management and freight costs.
Custom heat sinks from this line go into electronics that generate real heat.
If your part has a thermal problem, we have a geometry for it.
Q: How do you guarantee tolerance and quality? A: We machine to ±0.05 mm as standard. Every batch is inspected on a CMM, and we send you the report. If a part is out of spec, we remake it at our cost.
Q: What is your lead time for custom heat sinks? A: Prototypes in 7–12 days after drawing approval. Production runs in 15–20 days. For urgent orders, we can split the batch and air-ship the first 100 pieces.
Q: Can you provide material certificates? A: Yes. We supply mill test certificates for aluminum, anodizing thickness reports, and RoHS/REACH compliance documents. All are included with the batch inspection report.
Stop guessing if a supplier can hold your tolerances. Send us your PDF or STEP file, and we will confirm machinability within 4 hours.
You get a firm quote in 12 hours—price, lead time, and suggested design changes if we see a way to cut cost. No vague estimates.
