Your drawing. Our machines. A heat sink that fits exactly where it must.
We machine and stamp custom heat sinks from raw billet or sheet. Every part is verified before shipment. No exceptions.
We run a 20-year-old factory in Dongguan with four dedicated lines. Heat sinks are not a side business. They are a core product.
| Parameter | Value |
|---|---|
| Materials | Aluminum 6061-T6, 6063-T5, 5052; Copper C1100; optional nickel or anodize finish |
| CNC machining | 3-axis and 4-axis mills; positional accuracy ±0.02 mm, repeatability ±0.01 mm |
| Stamping | Progressive dies up to 250 tons; thickness 0.5–6.0 mm; burr height < 0.05 mm |
| Surface finish | As-machined Ra 1.6 µm; anodized (clear, black, or custom color) up to 25 µm thickness |
| Tolerances | Hole positions ±0.05 mm; flatness 0.1 mm per 100 mm; mounting surfaces ground to 0.05 mm |
| Batch size | 1 to 100,000+ pieces; no MOQ for standard alloys |
| Inspection | CMM reports, surface profilometer readings, and material certs per batch |
We cut, mill, drill, tap, and deburr in-house. For stamped fins, we build the die and run it on our own presses. That keeps tolerances tight and lead times short.
1. Batch-traceable quality. Every heat sink gets a job number. That number follows the material from incoming billet to final inspection. If you need to know which batch a part came from, we can tell you in minutes.
2. Inspection report per batch. You do not have to ask. Each shipment includes a dimensional report, surface finish readings, and material certificates. Our QC team measures critical features on a CMM and records them. You get the data, not promises.
3. One factory for CNC, stamping, springs, and heat sinks. Many buyers need a bracket, a spring clip, and a heat sink for the same assembly. We make all of them under one roof. That means one purchase order, one quality standard, one shipping point. Fewer vendors, fewer headaches.
Our custom heat sinks go into equipment that runs hot and runs long.
If your application involves forced air, natural convection, or liquid cooling, we can machine the channels, fins, or mounting pockets to match your thermal model.

Q: What is your MOQ? A: No MOQ. We prototype one piece and scale to 100,000. Tooling costs are quoted separately for stamped parts, but CNC-machined heat sinks have no setup minimum.
Q: How do you control tolerance and quality? A: Every part is measured against your drawing. Critical dimensions go on a CMM. Surface finish is checked with a profilometer. We send the report with 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 10–15 working days. Production runs in 20–25 working days, depending on quantity and finish. We can expedite for an additional fee.
Q: Do you provide material certificates? A: Yes. Every batch includes a mill certificate for the aluminum or copper. For medical or aerospace applications, we can provide full traceability documentation.
