Your drawing defines the part. We build it.
We machine custom heat sinks and vapor chamber assemblies to your exact geometry—hole patterns, fin pitch, base flatness, and mounting features. Every unit is verified before shipment.
We are a precision manufacturing factory in Dongguan, China, with 20 years of experience across CNC machining, metal stamping, springs, and heat sink production. One shop, full control.
| Parameter | Value | Notes |
|---|---|---|
| Materials | Aluminum 6061-T6, 6063-T5, C1100 copper, C1020 OFHC | Vapor chamber: copper base + sintered wick |
| CNC machines | 3-axis, 4-axis, 5-axis vertical machining centers | Up to 1200 × 800 mm work area |
| Finishing processes | CNC milling, skiving, stamping, brazing, vapor chamber bonding | Skived fin height up to 80 mm, pitch 1.5 mm min |
| Tolerance | ±0.05 mm (machined), ±0.1 mm (stamped) | Flatness ≤0.05 mm on base |
| Surface treatment | Clear anodize, black anodize, Ni plating, passivation | Thickness 8–25 µm per spec |
| Vapor chamber specs | Thickness 1.5–5.0 mm, effective area up to 300 × 300 mm | Leak rate <1×10⁻⁸ Pa·m³/s |
| Inspection | CMM, 2D profilometer, helium leak test, thermal resistance test | Report per batch included |
| Batch size | 1–50,000 pcs | No MOQ, tooling amortized per order |
All raw materials are sourced with mill certificates. Heat treatment and aging per ASTM B221 or your specified standard.
1. Batch-traceable quality. Every batch gets a unique lot number. We track material heat number, machine operator, and inspection data for each lot. If a problem appears in your field, we trace it back to the exact pour and shift. No guesswork.
2. Inspection report per batch. You receive a full dimensional report (CMM data), surface finish readings, and leak test results for vapor chambers—all before we ship. No surprise rejects at your incoming QC. We also keep samples for 12 months.
3. One factory for CNC + stamping + springs + heat sinks. Your heat sink often needs a stamped clip, a spring-loaded fastener, or a machined mounting plate. We do all of it under one roof. Fewer suppliers, shorter lead times, and one accountable partner. That is precision manufacturing without the runaround.
Custom heat sinks and vapor chambers go into equipment where thermal management is non-negotiable.
If your application generates more than 10 W/cm² at the source, a vapor chamber design is worth evaluating. We can help you decide with a quick thermal simulation based on your drawing.

Q: What is your MOQ? A: No MOQ. We run one-off prototypes at standard pricing. For production, we offer tiered pricing—1–100, 101–1000, 1000+ pcs. Tooling (if any) is quoted separately and amortized over your first order.
Q: How do you guarantee tolerance and quality? A: We machine to ±0.05 mm on critical features. Every batch is inspected with CMM and profilometer. You get the inspection report with the shipment. If a part fails your incoming check, we replace it at no cost—including freight.
Q: What is your lead time for custom heat sinks? A: Prototypes: 7–12 days after drawing approval. Production: 15–20 days. For vapor chamber assemblies, add 3–5 days for bonding and leak testing. We quote exact dates when you send your drawing.
Q: Can you provide material certificates? A: Yes. We supply mill certificates for aluminum and copper, plus RoHS and REACH compliance documents. For vapor chambers, we include leak test and thermal resistance test data per unit.
