Your drawing defines the part. Our job is to make it exactly to that drawing—no interpretation, no shortcuts. Every custom heat sink we ship is verified against your CAD file before leaving the factory.
We are a precision manufacturing factory in Dongguan, China, with 20 years of experience across CNC machining, metal stamping, springs, and heat sinks. You send the drawing. We handle the rest.
All values below are standard for our heat sink line. If your drawing calls for something tighter, we can usually hold it—just note it on the RFQ.
| Parameter | Value |
|---|---|
| Materials | Aluminum 6063-T5, 6061-T6, 1050, 1100; copper C1100 for high-conductivity inserts |
| Base thickness | 3 mm to 40 mm, depending on drawing |
| Fin height | Up to 120 mm |
| Fin thickness | 0.8 mm minimum for extruded, 0.5 mm for stamped |
| Fin pitch | 3 mm to 15 mm |
| CNC machining | 3-axis and 4-axis, ±0.05 mm positional accuracy |
| Surface finish | Black anodized (18–25 µm), clear anodized, or as-drawn |
| Flatness | 0.1 mm over 300 mm length on mounting face |
| Roughness | Ra 1.6 µm on base, Ra 3.2 µm on fins |
| Batch size | 1 to 100,000+ pieces |
| Inspection | CMM report per batch, material certs on request |
We use CNC machining for drilled holes, tapped threads, and milled pockets. For high-volume parts, we switch to stamping or extrusion, then finish with CNC for precision features. One factory, one quality standard.
2. Inspection report per batch. You get a dimensional report with every shipment. It lists critical features—hole positions, flatness, surface finish—measured on a CMM. You do not have to trust us. You can verify.
3. One factory for CNC + stamping + springs + heat sinks. Your assembly might need a heat sink, a stamped bracket, and a compression spring. We make all three under one roof. That means one purchase order, one shipping date, and one quality contact. Fewer suppliers, fewer delays, fewer excuses.
Our custom heat sinks go into equipment where thermal management is not optional. Typical applications:
If your part moves current and generates heat, we can cool it.
Q: How do you control tolerance and quality? A: We start with a DFM review of your drawing. Then we machine, anodize, and measure. Every critical dimension is checked on a CMM. The inspection report is included with the shipment. If a part is out of spec, we replace it at no cost.
Q: What is your lead time? A: Prototypes: 7–12 days after drawing approval. Production: 15–20 days, depending on batch size and anodizing schedule. We can expedite for an additional fee if your line is down.
Q: Can you provide material certificates? A: Yes. We provide mill certificates for aluminum and copper, plus anodizing thickness reports. Certificates are included free with production orders. For prototypes, we can provide them on request.
Stop guessing. Send us your heat sink drawing and get a firm quote within 12 hours. We will review the geometry, suggest cost reductions if possible, and confirm lead time. No obligation, no pressure.
