Your drawing. Our machines. A heatsink that fits your enclosure, your airflow, and your thermal budget.
We machine, stamp, and assemble custom heat sinks to your exact print. Every unit is checked before shipment—dimensions, fin spacing, heat pipe placement, and surface finish. No surprises on your line.
| Parameter | Value | Notes |
|---|---|---|
| Base material | Aluminum 6061-T6, 6063-T5, Copper C1100 | Or customer-specified alloy |
| Heat pipe material | Copper, sintered wick, Ø4–Ø8 mm | Optional nickel or nickel-plated finish |
| Fin material | Aluminum 1050, 3003, or copper | Thickness 0.2–1.5 mm |
| Fin spacing | 1.5–8.0 mm | Tighter spacing for forced convection |
| Machining tolerance | ±0.05 mm | Critical mounting holes and base flatness |
| Flatness (base) | ≤0.1 mm over 100 mm | Ensures good TIM contact |
| Surface finish | Anodize (black, clear), Ni-plate, or bare | Anodize thickness 8–15 µm |
| Assembly method | Soldering, thermal epoxy, or mechanical clip | Heat pipes pressed or soldered into base |
| Machines | 3-axis & 4-axis CNC, stamping press, skiving machine | In-house, no outsourcing |
| Inspection | CMM, 2D projector, thermal resistance test | Report per batch |
| Batch size | 1–50,000 pcs | No MOQ, tooling amortized per order |
1. Batch-traceable quality Each batch gets a unique job number. We record material lot, machine operator, and inspection results. If a problem shows up at your incoming QC, we trace it to the exact pour and shift. You get a full traceability sheet with every shipment.
2. Inspection report per batch We don't just say "it's good." You receive a dimensional report, material cert, and surface finish measurement for each batch. For heat sinks, we also test thermal resistance on a sample unit—not a simulation, a real measurement with a thermocouple and heater block.
3. One factory for CNC + stamping + spring + heatsink Your heatsink might need a stamped clip, a spring-loaded fastener, or a CNC-machined base plate. Most suppliers send those out to three different shops. We don't. All four lines are under one roof in Dongguan. That means one purchase order, one quality system, and one shipping date. No coordination headaches.
Our heat pipe heatsinks go into electronics that generate serious heat in a small space.

Q: What is your MOQ? A: No MOQ. We make one prototype for your thermal test, or 10,000 units for production. Tooling costs are quoted separately and amortized over your order quantity.
Q: How do you control tolerance and quality? A: CNC-machined features hold ±0.05 mm. We inspect 100% of critical dimensions on the first article, then use SPC sampling during production. Every batch ships with a dimensional report and material cert.
Q: What is your lead time? A: Prototypes in 7–12 days after drawing approval. Production runs in 15–20 days. For repeat orders with no design change, we can hold safety stock and ship in 5 days.
Q: Do you provide material certificates? A: Yes. We provide mill certificates for aluminum and copper, plus RoHS and REACH declarations. If you need specific certifications (e.g., UL for plastic parts), tell us—we'll source and document accordingly.
Upload your PDF, STEP, or IGES file. We'll review the geometry, heat pipe layout, and tolerances. You get a firm quote in 12 hours—price, lead time, and tooling cost if applicable.
No MOQ, no minimum order quantity, no runaround. Just precision manufacturing from a factory that's been doing this for 20 years.
